02 CR 80 trouble

I have an 02 Cr80 that's having some trouble starting. The carb is cleaned, it gets spark, gas is good, and it has a brand new top end with about 2 hours on it. Sometimes it will start for about 30 seconds to a minute and bog out and die. Me and my friends are out of ideas as to whats wrong with it. Any suggestions?


You already posted pretty much this exact same post before not too long ago... You should use that thread instead of starting another duplicate one.

With that said, did you check all the items people suggested in that original thread?

reeds ? float level ? weird obstruction in air box or exhaust? carb settings , air screw idle screw ? .......you didn't put the piston in right ....
