I have a 1978 Puch Maxi Sport MKII. This past winter I completely disassembled it, polished the chrome and rebuilt the engine. I noticed when I was re-assembling the engine/carb that the gaskets were somewhat worn, but they didn't look cracked. Since I had to head back to college, I wasn't able to replace the gaskets. I took the moped for a quick test drive and it seemed fine. Quicker acceleration and higher top speed. A few weeks ago I went home to pack stuff up for my move to DC. The ped seemed fine until I took it downhill, it started to 4 stroke, then died. I was unable to get it started again, but it did turn over. I tested the spark, the plug is a nice toasty brown, checked the compression, I adjusted the idle and speed screws but I could never get it to start running. I sprayed carb cleaner in the head, and it would start, but then died. This leads me to think I need to replace the gaskets? Im headed home again in a few weeks and I would like to have the parts waiting for me at home. Since I dont have access to it at the moment, its hard to troubleshoot. I would like to bring it down to DC since it would be awesome in the city, but its too hard for me to try and repair it down here, so I need to fix it at home. Any help would be appreciated.
(sorry for the long post, wanted to give as many details as possible)
