Puch Maxi cutout

I have a 76 puch maxi s. The problem its started to have is when i hold it to wide open throttle it cuts out. I held it wide open and waited a few sec. till it cutout and had my friend spray some wd40 down the carb and once he did that it picked right back up again. I've taken the carb apart and cleaned it out really well, tried adjusting the float but nothing seems to fix it. Its running really well except for the WOT cutout.

Re: Puch Maxi cutout

sounds like your a little bit lean. did you take the airbox off?

Re: Puch Maxi cutout

Typical fuel delivery problem, jury rig a small can as gas tank directly onto the carburator, run it on the stand, you will at least illiminate the clogged tank filters and petcock. If it still acts up the problem is in the carburator, clogged jet pipe sounds like fuel starvation.
