Just add another nut to the end of flywheel, then you can add a bolt that secures the degree wheel. Pointer must be secure (I use a clamped on scriber) & degree wheel should be as big as possible. Barrel must be bolted down well or gives incorrect readings, this can be a problem if engine has thru bolts & a few gaskets used. Use feeler gauge to determine if port is closed by piston, doing it by eye is imprecise.
When starting with another carb just pull the mainjet out, no point putting a big one in. If the engine doesn’t bog past ˝ way then the needle is too fat.
I've been told. Dreaming`s free.
Think I'll go, back to sleep.
Everybody listen, voices in my head
Everybody listen, do yours say, what mine says?
