Not getting enough fuel to one cylinder at idle. Did all the normal tricks:
* checked idle jet (clean) * ran idle mixture screw in and out * removed idle jet and mixture screw and blew out * removed idle jet and "plugged the hole" with finger (this should give me a *very* rich mixture, only got down to 15:1 or so) So, it's time to pull the carb. I suspect something is blocking the mixture screw area... Of course I have a race this weekend. Sigh. |

Check your valve settings on that cylinder and do a compression test..
OR. Flip the carbs from one side to the other... Carbs dont care if you have a spark, they are only controlled by the airpump...some evacuation will affect it..but not unless you have built the motor for that... Flipping carbs sucks, but its an hour... Rich |
