Default Re: Infernal Machine - Help

excess smoke is usually due to fuel in bottom of motor, or sometimes collected in cap of muffler - one typically just runs it a while to blow it out

if muffler is clogged by burned oil, it can be loosened just a bit at cylinder and tested to see if power returns, if so replace or clean out muffler

check for oil residue around head gasket and case seams for compression loss - tighten as needed
Sometimes I sets and thinks, sometimes I jes sets.
