A completly noob question.
I instaled and billet flywheel and sparks plug get really dry dark after some laps engine bogs at low rpm until it fails.
What is normal degree timming on a gx390? i have a 6 degree key installed.
my engine has stock crank, modified cam, 30 mm carb with big air filter, harder springs, rpms are prob 6000.
The flywheel already has 24 degree with stock key, should i change key to stock or just change carb low jet to a smaller one.
Thanks alot.
