back-fire problem

[honda83]

My 185s back-fires a little when i give it full throttle real fast. The air filter is new. The carb looks clean. I checked the timing-clearance in CDI, it was good. i placed the mixture needle in the carb where it should be. It is not lean, but I can tell it is still running to rich. What could it be, should I rebuild carb or what?

thanks for the continued help.

Check your timing, take the check screw off of the flywheel casing(Large sloted screwdriver screw) Then look for the t and line it up with the notch. Then remove the cdi cover and line up the timming marks.

Do you have a manual?

I opened the flywheel casing and don't see any mark or anything.
I am confused, any help?
thanks

Weak igniiton. Hitting teh gas really hard dumps raw fuel in the cylinder, its not burning off and loading up in the engine. Check compression too, valve might be leaky.

If I have a weak ignition, what do i do to check or change it?

What collor is your spark? put the plug in the boot and let the plug rest on the just then pull it over and see what collor it is!

could be the rockers are adjusted to tight.

check spark plug gap could be getting blown out at wide open throttle
