I will look at the tube! thanks...no one has brought that up yet and I never thought of it..
I have been playing with the idle mix screw It does have an effect but I still can't seem to get it to idle low enough I'm kind of saving the timing for last. I'm assuming Moyer set that precisely before it left their shop and I really don't want to mess with it yet. The choke seems to want to be fully open. I have a spare carburetor I rebuilt last year sitting in my toolbox. I'm going to swap that out next. That "should" eliminate clogged jets as a possible problem. I just put the plugs in this season and gapped them to spec, They are all a nice golden brown color. Here is a link to the carb with the flame arrestor removed http://sdrv.ms/14SwiMr ...and here is one of a the #1 spark plug http://sdrv.ms/1eZpLVP You can probably scroll around and see other photos and a couple of videos of the engine running. ---------- Original Message ---------- From: "jtsails" <jtsai...@gmail.com> To: <md...@ca.inter.net>, <cnc-list@cnc-list.com> Subject: Re: Stus-List Atomic 4 Carb things to try.
