Hi all, I've been reading the forums and I have a few questions before I rebuild my carbs. In my manual it shows two types of carbs. One has the low speed adjustment needle and the other has what looks like a fixed jet. I have the fixed jet carbs. My motor runs really rough at idle but when I give it WOT it takes right off and runs great. I throttle back and it gets really rough and sometimes stalls. In the rebuild kit it comes with these little caps for the top of the carb. Some say to drill a little hole in them to pop them out and install the new ones with some finger nail polish. Do I have to take them out or if they look of leave the old ones in. What is under these caps or do they just wear out. The other question I have is the fixed jets. They seem to be in there tight. Do I need a special screwdriver to remove them to clean this area or leave them in and run some carb cleaner through them with some compressed air. Any help would be greatly appreciated.
