Well, I finally got my 77 Puch Maxi running pretty good.
The third piece of ultra thin stainless steel wire in the jet seems to have gotten it just right. I can hit 30-32 mph right now, and it accelerates quickly. Also, I took some of your suggestions and did the following 3 things to the airbox.
1. Cleaned with gas, and blew out with forced air.
2. Removed the snorkel.
3. Cut off the nub that the snorkel came out of (as if the snorkel was the nipple and the nub was the aeriola of a titty).
After riding over a mile or so however, the engine can be a little tough to turn over. I have to peddle down the street, then hit the starting clutch to get the engine to turn over. Then it runs great. I truly do not believe that the engine is siezing up because after it starts it runs free and easy, no lag or drag whatsoever. Any thoughts??
