1977 puch maxi will only idle with pipe off

I bought a puch maxi s about two weeks ago. Everything seems good, but I can't get it to idle. I just a performance pipe and it will not idle with it either. When the throttle is fully open, it boggs down. When I was switching pipes, I started it without a pipe and it idled fine with no problems. The jet is a 62. I'm not sure if that would have anything to do with it and I put a hi air flo filter on it. Thanks for any help or suggestions!!

You got to get a aftermarket pipe like a techno circuit .

Stock pipe is junk even unclogged . It's only there to make you go slow.

More air in = more air out . 2 stroke engines need a expandsion chamber pipe like aftermarket ones.

Don't waste your time trying to unclog it cause it's so restrictive you will never get it jetted correctly/run right

Oh ya it's hard go see all the print on this small screen

Anyway upjet to like 66# jet if you got a 2 hp cylinder, 12 mm carb with # 222 atomizer.

If you got a 1hp well you got to swap out your cylinder
