: oil keeps rising in pony engine
Reason: Gas on starting engine is getting past the shut off valve and needle and seat will let enough gas to get past to cyls, runs past the rings and into crankcase. Have had it happen numerous times and if gets deluted enough will stick the valves or even the pistons one time.
