--> KR-List message posted by: <[EMAIL PROTECTED]> My Great Plaines 2180 VW has a little miss at low RPM 1100 or less. What I might call a bit of a stumble miss but very slight. By 1500 RPM or better, everything seems fine. It seems to me that it has always done this but I will ask for advice giving you as much information as I can.
Running a single mag ignition, autolite automotive plugs ( they are the substitute for the Bosch WA 8 plugs GPAS calls for) narrow gap .028 per Steve Bennets book., Zenith Carb, K&N cone filter. As I mentioned, it seems to me it has always done this but I am wondering if some day on final , I go to pull the throttle back and it quits on me. So I will also mention that I am burning off some older Av gas, many months old as the plane has been under various stages of getting it back together. Also, just a little note of interest. I just had Jet Hot ceramic coat my 4 into one exhaust. They do it inside and out verses others who only do the outside of the exhaust. Anyway, since the exhaust coating, I can now peg the tach past 3500 RPM verses previously getting 3200 RPM and maybe on a rare perfect day getting around 3400 RPM. I mention the Jet Coating since that is the only thing I did to the engine and then getting a sudden increase in RPM. Yes the days right now are cooler but the engine has 56 hours and has run on many cool days before. Jeff York Lexington, KY.
