KR> Fuel Systems

Terry Chizdek, Thanks for grouping the fuel systems info together.I have been off the net for some time and picked up the tail end of the thread. Thanks Terry. Eric Evezard, South Africa.

KR> Fuel System

Dave, What sort of carb/carbs system do you have.Do you have the float chamber and needle valve shut off system such as a Zenith/Stromberg or do you have a throttle body type such as a Posa/Ellison.? Regards, Eric, South Africa

KR> Wing Pins

Hi Netters, My questions about wing pins could have caused concern.Using wing pins in a sailplane is a recognised standard practice.The weight/load of the wings whether parked or flying impose a terrific locking load on the pins with the WAFs They wont budge.For example removing the wings requi

KR> WAF

Hi Netters, Has anyone used wing pins to attach the wings ?My sailplane has wing pins with small handles and thumb push buttons one end with ball bearings at the other.One simply presses the thumb button,the ball bearings retract,and the pin slides through the WAFs,Let go and it is locked.It tak

KR> Dive Brakes

Hi Netters, Thanks Patrick and Robin for your input.A netter calculated the load on a typical KR dive brake as about 130 lbs,deployed.I tried my brake at 2600 rpm static and while the lever pull was firm it was quite comfortable,and gave me a ball park idea of what to expect. Best Regards, Eric,

KR> Dive Brakes

Hi Netters, Dive brakes have come up on the net again,mentioning dive bombers.The WW 11 Douglas Dauntless dive bomber had dive brakes that could be described as a whole lot of holes held together with very little material.This may suggest that the holes cause turblence and drag.The question aris

KR> HUB UNIT

Hi Neville, I will contact you off Kr net about hub units. Eric, S.Africa.

KR> 2nd ignition

James , Thanks for the tip but I am using two completely different and independant ignition systems.For example,I am not sharing the coils,from two identical systems.The one system uses one coil serving a distributor with four plug leads.The other system uses two coils each one serving two plug

KR> 2nd set plugs

Hi Dan, Thanks very much for your response.I have a 2 L type 4 VW engine that runs exceptionally well on a distributor similar to a Bosch type 009 distributor imported from Great Plains.and standard VW plugs.I have installed a backup system that will need an extra set of plugs.Thanks for clarifi

KR> 2nd set plugs

Hi Netters, Shortly I hope to have a second set of spark plugs installed for dual ignition.Are there any do's or dont's of note ? Should one have the helicoil steel inserts for example ? Best Regards, Eric, South Africa

KR> IGNITION

Hi Netters, Thanks Dean for the offer about "that" ignition.At present I have a Bosch 009 type imported from Great Plains Aircraft which is excellent.I do however wish to install a secondary system and I need a wiring diagram to make sure.Please contact me in SA Address: 24 Lotus Avenue,

KR> IGNITION

Hi Netters, Does anyone have a wiring diagram for the Honda m/cycle CDI ignition 1980 to 1983 CB series.4 cylinder motorcycle Ignition System ?..A number of KR s have used this system very successfully. Thanks, Eric, South Africa

KR> WHEEL SPATS

Hi Netters, Thanks Mark and Sid for the sound advice on wheel spats.Really makes sense and I am definitely going to go that way. Best Regards, Eric, South Africa

KR> WHEEL SPATS

Hi Netters, What would be a typical thickness to accept for fibreglass wheel spats ? Best Regards, Eric, S.Africa

KR> WICKS

Hi Netters, After going through WICKS catalogue on line I ordered a part which arrived here in S.Africa a few days later.All done on line,no fuss,no bother. Great !! Best Regards, Eric

KR> Thanks

Thanks netters for the addresses I will give it another try later. Best Regards, Eric, S.Africa

KR> Address

Hi Netters, I have had no luck in trying to contact Steve Glover on the addresses he gave on the net.I am interested in purchasing supplies but my attempts have been returned as undeliverable.Any suggestions ? Best regards, Eric, South Africa

KR> cooling

Hi Dene, In a motorglider one is caught between a stone and a hard place.Ample cooling,intakes,eyebrows, vertical gills, are fine to cool the engine but when you stand on the wingtip and corkscrew up in a thermal,engine off,the drag of this cooling will degrade the gliding performance and worse

KR> Dan

Dan, Glad to hear your are OK.Get well soon. Best Regards, Eric, S.Africa

KR> Timex fuel

Thanks Larry and Sallie for the info on timex fuel.I still have your video ---landing on grass and high speed fly past on my desktopinspiring !!! Regards, Eric, S.Africa.

KR> Timex fuel

Hi Netters, Just been reading a lot about the evils of time expired fuel,yet theres nothing to state how long it takes for AVGAS to deteriorate.I have been given so many conflicting times by different sources that I thought I would consult the experts our netters. Furthermore,there seems to

KR> O 2

Hi Netters, It is surprising to see that some aviators are venturing above 10 000 ft without oxygen.The effects are insidious and that feel good feeling can lead to disaster.Reaction varies from day to day per person.I have an old WW 11 A8a constant flow system in my sailplane,with excellent res

KR> L/D

Hi Netters, It is,in my opinion,the terrible twins "lift and drag " are the ones to watch,in fuselage shape.or wheel spats.These twins are joined at the hip !! .If there lifting there dragging.Try for a streamlined fus.with good gap seals at the tail feathers.etc.taking care with the angle of in

KR> Trim Tab

Thanks Mark,my trim tab is right there.Some books say trailing edge freeplay on the elevator trim tab must not be more than 3% of the tab chord.I am ok there as well.However I am going to stiffen up the small pushrod to the trim tab crank.It just looks a bit flimsy . Best Regards, Eric, S.Africa

KR> Elev.Trim Tab

Hi Netters, The archives have much on elevator trim tabs,but as a short cut,how much up and down movement should there be on the elevator trim tab on a KR with good CG range as specified.? Regards, Eric, S.Africa

KR> Great Plains

Thanks Al for letting me know Steve Bennet of Great Plains sells instruments as well.Best news I have heard for a long time.Ordering,Payment and timeous delivery is excellent even to this side of the world. and hassle free.!!! Willie if you are going to use a Tiny Tach from a two stroke two cylin

KR> Tiny Tach

Hi Willie, The Tiny Tach tacheometer has worked very well for me.It also records hours.The end of a lead is simply wrapped around the nearest plug wire for about four turns.Some have had poor results but remember when ordering to state whether two stroke.four stroke.two,four or six cylinders.In

KR> O2 gauge

Hi Netters, Has anyone used the SKYHAWK fuel/air ratio gadget.? I bought mine at a garage sale and is normally used for auto tuning.It is about the size of a car battery with a very large dial and thin needle,giving clear readings.Of course I tune on the ground only but one simply clips onto a 1

KR> Foams

Hi Netters, Let us remember that some foams give off a very toxic gas when cut with the hot wire method. Regards , Eric

KR> float bowl

Mark and others.Thanks for drawing attention to the danger of carb float bowl air pressure.I have twin Stromberg (Zenith) carbs,with the float bowls each vented to the air intake,before the butterfly valves in the the carbs.Carb heat is collected with scoops on the left and right exhausts near

KR> Engine Run

Phil,I had a similar problem.It turned out to be a perforated diaphragm and the right carb vacuum could not lift the piston to lift the needle needed to increase fuel into the intake system.There were two invisible holes the size of match heads.Holding the diaphragms up to light to look for hole

KR> Pitch/Revs.

Hi Netters, I cant find a formula to calculate the prop pitch/rev relationship.For example if a certain engine gives 2000 rpm with 52d/48p at max .what reduction in pitch will give 3000 rpm. ? best regards, Eric, South Africa.

Netters, Please accept my condolences on the passing of Ron Freiburger.Many years ago I had the privilage of contacting Ron personally for his much valued advice. My sympathies to his friends and family. Eric Evezard, South Africa

KR> Oil Temp/pres.

Netters , My type 4 VW was remanufactured by a VW factory and I received it with an oil pressure switch mounted near the distributor hole.This switch was intended to operate a red oil pressure warning light.I replaced this with an oil pressure and red light sender to an oil pressure gauge and o

KR> RPM

Hi Netters, I am getting 2100 rpm with a 52/48 prop static.The engine runs very smoothly,and responds well but on increasing throttle at 2100 rpm the engine quietens and revs drop.On throttling back I can get 2100 again and very smooth running.The engine is a 2 l VW as new,running on twin Zenith

KR> Thanks

Thanks again netters for your information.It is really appreciated,believe me. Phil,I have seen the pics. of your mishap.Devastating !!! All of the best and lets see you back up in the saddle again ,soon. Best Regards, Eric, South Africa

KR> VW timing

Netters, I really appreciate your expertese and clarifying this timing thing.It is all so clear now. Many Thanks, Eric. ZU-BMP ZS-GML

KR> VW conversion

Hi, Can some netters kindly explain why VW manuals give 7 deg BTDC and aero conversions give 25 to 28 deg BTDC as the timing.?. How does one "tweak" the VW to use 25 to 28 deg BTDC.? Best Regards, Eric. ZU-BMP ZS-GML

Scott and Jane --correct 24kg/cu.m is the same as 1.5 lbs/cu ft. but 1.5 lbs is 24 ounces so back to square one 24 density.Strangely 24kg/cu.m is the same as 24ozs/cu ft. Best Regards Eric Evezard S.Africa
