Somebody recommending 5* of advance for this engine is somebody who does NOT understand combustion fundamentals....
What's wrong with you? Is English not your first Language?
Firstly; your "somebody" has a name;
they call me AJ.
Secondly, Did I tell Op to set his timing to 5 degrees?
Thirdly, did I even say I would set his timing to 5 degrees?
No, I did not, Go read my post.
What I said was ;
"I can make that thing idle at 550 in gear and pulling itself on flat level, hard ground with 5 measly degrees of Timing advance. Maybe even 500."
OP's combo will not be the first one, in the which, I have proved this to be true; which is why I can say that with confidence. Where I will actually set it to, well, I will let the engine tell me.
None of us need nor want your snide/underhanded, borderline cowardly, comments.
Listen; when you say stupid chit on the forum; I don't say nothing against you, I say my piece and let OP decide for himself. You would do well to do likewise.
I'll tell you what I'll do, just for you;
When OP gets here, well crank the Idle-timing to 25/30 degrees like you said in post 13, and report back. Let the truth come out.
