[rebel-builders] Engine Running Rough
Posted: Sun Feb 19, 2012 11:42 am
Running car gas or 100LL ?
I'd suspect a slightly fouled lower plug before going chasing anything else.
With 30 hours and if you haven't been leaning religiously..it's time to
rotate the plugs in each cylinder with a good plug cleaning while you do.
Also check each lower plug for signs of oil as you go. May have one cylinder
with ring blow by or valve guide clearance that's letting oil into the lower
plug/cylinder during shut down.

Doing a few snags after putting 30 hrs on R776.My 0-320 160 hp is
really rough for 2 or 3 seconds when starting.The 0-320 150 hp in my
friends PA-12 is smooth running as soon as it starts.Are all the 160 hp
rough on startup.I have priming lines on only two cylinders,would this
cause the engine to be rough on startup.Do all you guys
prime four cylinders.
