I am looking for a couple of things. First, does anybody know where to find good schematics, diagrams, and tuning guides on the Net for Mikuni Carbs? And, does anybody have advise on the following?
I have a 250cc Elan. It has the Mikuni VM carb (round slide). Last year it ran strong. Ok guys, I can hear you muscle sled heads laughing. Careful now! This year, when I pinch off the throttle, and go just as absolutely frightening fast as an Elan will go, I lose power and it backfires.
I took the carb apart twice. I have soaked it in aerosol carb cleaner overnight and run wires through all the jets and orifices I can.
I have yet to check the tank and fuel line into the tank to be sure I don't have a vacuum or blockage. Pretty sure the vent line is clear, need to pull the fuel line and check it.
Any great ideas? Thanks.
