Hi guys Had some unexpected teething problems so far To start with, before first flight, the Rotec TBI gave nothing but trouble, running too lean and cutting out about 3/4 throttle. Modified a few times by Rotec, finally got to WOT , then cuts out, but they refused to test run it at WOT( see their web page, on how they test them , think very hard before buying a new one. They refused to refund my money, that wasted months.
So purchased and fitted the Correct 0200 carburettor,$$$$$ fixed the running problems. Then running hot, so, more time taken to modify cowl inlets from 3 inch to 5 inches. That was fun cutting up a beautifully finished cowl, but fixed the temps so far. But not summer yet??? Will Finishing off cowl painting after testing is finished. Then, the prop 60 x 70 was too much for the engine, low RPM. static 2100 , WOT 2400 , no were near the specifications of 2750. So flying has been a bit restricted. Unable to borrow a lower pitch prop to try. Waiting on a new prop 59 x 68 $$$$$$ Then after about 7 hours the left mag failed, so they had to be sent away. Found out both unserviceable, so had to order new ones. $$$$$ That fixed that problem, More lost flying time Now only have 11.5 hours on clock Next minor prop, when I built her I, placed two thin ply packing shims under rear HS rear spar ( -3 deg) as discussed on the KR net. Had to use too much forward trim, so removed one shim a few days ago, seems better , but weather has been so windy and rough, test flying is very difficult. Hope the new prop from Nee Zealand arrives soon, and proper testing can start, ( if weather allows) this is my first tailwheel aircraft. But it handles great on the ground, and still in one piece so far. Testing Can only get better. To be continued Phil matheson Australia VH PKR KR2Ss- continental 0200.
