So, I got the 1980 Puch started today after cleaning the gas tank over the past few days...thanks for all the advice on that.
The moped idles ok but doesn't have much power and bogs down when I try to get it going any faster than say 5 mph or so. Won't even get up the small incline on my driveway.
I cleaned the carb also. The ignition looks good to my eye - points have about a .018 gap or so (eyeballing it) and are open when the timing mark is about 4 o'clock. I also have a new spark plug.
Thanks for any ideas.
