So I just bought a Newport off of a guy, and it drove like an absolute champ. I got it home, and the next day, same thing - running fast as hell.
The next morning I got up, put a little gas in it, and it's going like 25 tops ... and it's struggling to get that. So I figured I had my mixture wrong, so I called the guy that sold it to me, and I did the same mixture he did (original mixture: 2.5oz per gallon. New mixture: 3.5oz per gallon).
I drained my tank fully, ran all the gas out of the carb, and put my new 3.5 mixture in, along with my friends Pinto - still slow, but his is fast.
I pulled off the carb, completely cleaned it, cleaned the screen inside the banjo, and stared at it for about an hour. No luck.
What could this be?
Thanks so much
