Dear Spridgetland,
Before I operate I wanted to throw this our for comment or ideas.
Dear old McGee, my 75 Midget now has dual 1.25 carbs and a manifold from a 1300 Spit. New carb needles have been installed and the motor runs well except..........it idles at 2000rpm!
I've sprayed down the intake connections to head and carbs with WD and couldn't detect a leak. Other info: The motor may have accidentally ingested foam air cleaner material( I wont say how but it was stupid). The motor idled at the proper rpm when I first got it going then it increased. Cylinders 3, 4 are running lean.
Operating hypothesis is to blow compressed air down the bore of the back carb and flush out any material messing with the carb function. In other words I think it's sticking from "stuff" in there. Any other possibilities will be happily considered.
