I haven’t flown the rv in about 3 months, but today, I
Went to fly. However, after starting, the engine ran rough.
I shut it down and took the cowl off to try to find the
Problem. Cylinders 2,3 and 4 were very hot, but cylinder #1
Was not. I immediately thought stuck valve , so I removed
The #1 valve cover and all 4 top plugs. When turning the
Prop by hand, the valves seem to move normally. I put the
Valve cover and top spark plugs back on and Turned the prop
Though 4 blades. All compression strokes are about the same.
I’m not sure what else to check. Any help??
Carburetor and slick mags.
