Back in the fall I had my Puch Maxi Newport refurbished by the Detroit Moped Works. Then it managed to sit pretty much unused until spring. With the arrival of nice weather this Memorial Day Weekend I got it out, and checked the tires and sparkplug, put some new gas in it and sprayed down the chains with chain lube. Two days ago it started OK and I rode it about 100 miles in a day. Great.
Then the problem surfaced yesterday morning.
After I started the bike it acted "weak" If I opened up the throttle to full it would start to die. I had to run the motor at about 1/4 to 1/2 throttle to get the motor to run, and it would not power up the way it ought to and the motor was slow and weak. Then when I gave the motor some assist by pedaling, it decided to come to life and power up all the way. Very strange. When the folks at DMW rebuilt the bike they put a 70 cc "Top End Kit" on the bike, with a new carb, (15 mm dellorto) pipe, and cylinder head. (This has made it possible to actually keep up with urban 35 MPH traffic a lot better.) But after this strange start event yesterday I consulted my friend rebel moby about it and he recommended that I ask "One of the Puch Experts at Moped Army about it". So here I am and I am asking about it.
