I am having problems with my recon it is popping out of the exhaust at idle and then cuts off after idling a little bit.

How does it run above idle? And under load? Have you replaced the NGK spark plug yet?

 

[Samman]

It runs good but still has the popping sound and I have Changed the ngk spark plug.

Sounds like fuel line or carb passages clogged. Is fuel old? Empty tank, clean petcock, fresh fuel with Seafoam cleaner.

If still runs rough then clean the carb

 

[Samman]

It gets gas to the carburetor and it as fresh gas in it. And I have also cleaned the carb

Maybe ya got an exhaust leak somewhere. Or a leaky intake manifold. Do you still have the OEM carb and air filter, or china knockoffs? Also adjust the valves while you're poking around the carb, intake and exhaust system, make sure those are lashed right.

 

[Samman]

I have the own carb and air filter.

backfire is a lean condition. When you cleaned the carb how did you do it? Complete disassembly?

The jets may be clogged — i use pipe cleaners

The pilot screw may be assembled incorrectly or not set proper amount of turns. Mine had the tip of the old one broken off in the bore

The air cut valve may be involved
