Upper distributo has Gear on upside down. Push roll pin out and flip it. Sound like a fuel pressure issue, not keeping up with demand or fuel quality?

Can you guys tell me why one gear is higher than the other because I don't have a clue.

LOL....reminds me of a conversation I heard at a homes for humanity site "the head of the nail is on the wrong end".... "ahh Its upside down"

That pic brings back bad memories... I put the new gear on my distributor backwards like that when getting ready to put my engine in my car. Took me about a week to figure out why the distributor wouldn't fully seat.

Was looking back through pictures i took as I pulled everything apart, saw a picture of the distributer before the gear change a BINGO...a light goes off in my head.

So the next million dollar question..........50cc accelerator pump or bigger jets.

I got a SWAG that won't waste any more of your money.

Pull your filter off and blow through it. If your ears pop, its 30% plugged. If an eye pops out then its 50%. If you crap your pants its just Miller 30. LOL

Hey, so news flash......was talking to Joe Pecavar about springs and bushings for the new dizzy and he says go with what you had because that's how we tuned it. He asks me what bushing the old dizzy had in it. I go to look and the mushroom cap that the weight rides on was gone. Guess what cracked my distributor cap and rotor and has been screwing up my timing?

Well, I was going to post up and say its an ignition issue, not a carb issue. But looks like you may have found the culprit!!

Yup....Definitely an ignition issue. Come to think of it.........if your plugs are a medium charcoal color that right there tells you your getting motr than enough fuel

Not unless you shut it down at wot. You are looking at the idle burn.

Your total timing should still be fine without the bushing. That effects how much initial timing you have. Now, I can see the bushing bouncing around in there causing the misfire.
