84 200es, Doesn't want to idle. It has low compression could this be the problem? IT idles fine in the old 3 wheeler, but I swappedengines and it is in this new 3 wheeler and I"m thinking the carb isnt set up right. I can set the idle super high and it will stay running but its half throttle pretty much. When I put it lower it will slowly idle down untill it stalls. How do I set it up to idle? It runs fine, just wont idle. What about the mixture screw, and the rich/leab clip, can I chaneg anything to make it idle? or maybe there is soo little compression it just cant get enoughpower to keep running.
