NO fuel left side gl1100 - 80

[zajt@hotmail.com]

Hi. I have som issue with the fuel in cyl 2 and 4. Ive checked so i have spark... Changed coil from left to right side just to test. Cyl 1 and 3 goes fine. Have cleanded and rebuilt carburators( by my self with help from Youtube and randakk). Checking fuelmix with Colortune and there is spark and only a slight blue spark if i give nearly full throttle. With Idle there is only spark. New plugs. When i open drain plug on 2 and 4 carburator there comes fuel. There is also vaccum, checked with indicator, on all four cylinders. Heaters on left side is nearly warm, no problem to hold my hand there, when i warm up The bike. Checked timing and valves so they are correct. Air/fuel screw doesnt change anything when adjusted. 1 1/2 turn from start. Have checked floaters probably three Times so i think i got them right. Any suggestion that i might have missed? Oh...Also checked Compression... 10 on all 4 cyl. Any ideas and tip...i'd be very glad to here.

I'd suspect plugged idle jets, I had same thing happen on my '80 1100 on the right side.

The jets on 1980 are removable, look for you tube videos for "How To".

Many thanks. Idle jet was the problem!
