OK... just got the moped bug, and have a PA50i and a PA50ii.
The PA50i is immaculate... 1979, 350 miles, the PA50ii is 1978, 4000 miles and has been sitting outside unused for quite a while!!
I worked on the i for a few days (carb and petcock cleaning primarily) and have that running pretty good, but it tops out @ 15MPH (I am 120lbs), won't idle and has a completely "wooly" throttle response.
I would like to swap the engine from the ii to the i, because the running gear on the i is so good and I would like to hit the magic 30MPH!!. The question is, is this a straight swap??
I have found the shop manual online, and removing the engine does not look to difficult... but, when I come to install it in the i chassis, will it bolt in the same way?? Will the belt be OK?? etc, etc.
I really would appreciate some assistance... y'all have been invaluable so far!!!
Thanks a ton,
