Can someone please help me?
Ive got a 36DCD Weber on my R10 1300, which was running fine. I removed and re-fitted the cylinder head to fix a top end rattle and after re-fitting every thing, the car will not run. It fires up o.k. but will only run for a few seconds before flooding and cutting out. After all the usual checks, jet cleaning (with compressor), etc.
I tried it with the air filter removed and then noticed that the main jet discharge nozzle (was pumping out a lot of fuel while cranking and when running (1000 to 2000 rpm). This is causing the engine to emitt black smoke and then cut out. The needle /seat is almost new and no leaks in floats.
Acording to my limited knowlege and experience, I'm sure the main jet should not be operating at such low revs with no load. Whats even more puzzling is that I have tried 2 different carbs(after transfering the jets and choke tubes) and the still the problem persists! I have tried lowering the float level to 6mm in lieu of the specified 5mm, but the problem remains. I've stripped the carb and cleaned jets and fuel ways/air ways a half a dozen times....no luck.
I need help, or a box of matches!
Cheers,
Henry
