Re: jumped timming

You can check the timing, but it is doubtful......
Backfire through the carb is generally either a tuliped intake valve or a lean fuel condition.......
I vote lean fuel condition.....
A simple compression check will rule out a tuliped valve.....​

Re: jumped timming

It may have not started because it was not getting any fuel. I would check to make sure it is getting fuel.

Have a great day,

Rob.

Re: jumped timming

Points closed up.Bad points/cond.Water in the fuel.Bad coil.If it's just been rebuilt and you replaced the timing chain and gears(you did change them didn't you) Then it's probably something simple.Jerry

Re: jumped timming

Cause you drained the tank don't mean your out of the woods.

Keep cleaning the filters. About 3-4 tank fulls till they stay clean. Have a fuel water separator?

Oh don't forget about the fuel pickup tube in the tank. Has a screen on it.

Good luck !
