Hey all,
I'm trying to tune a potentially messed up pair of carbs and here's where i'm at:
Before, each float was way below 15.5mm and the engine was getting flooded with gas. It would start and run on 2 cylinders (2 & 3 would fire)...cylinder 4 would fire every other time...and carb 1 didnt fire at all.
Each time I would pull the carbs there would be little puddles of fuel on the intake boots. Also...there were droplets of fuel coming OUT of the engine exhaust!! (i don't have the pipes on there..so i could observe the drops right out of the engine body)
I went back and ajusted float heights to 15.5mm above the bowl lips...this was a little tricky. They didn't want to go up that high. Got it with a little tinkering though.
Went back out...same issues.
Too much fuel. Already my fuel screws were maybe 1 turn...maybe 1 1/4 out. So i decided to just close them completely.
Wiped everything off...fuel screwes were closed (tightened all the way)...put everything back on the bike...craked it a bit. Pulled the carbs off....same puddles of fuel!!! what gives? is this supposed to be? Its as if eveything i'm tuning makes 0 difference!
So...i'll mention that there was also a "no-spark" issue...because all the plugs got soaked. only plug 1 was alive. I cleaned the plugs with carb-cleaner. dried them off...tested each on..and tested each of the wires...they all now work and i can see little sparks jumping on the plugs when i ground them to the engine.
Spark issue aside, when i close off the fuel screws and crank the engine...should there be gas going in at all???
Thanks in advance guys
