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. |

I should mention that I also checked the screen at the fuel inlet of the carb and it was pristine. I run a FI style fuel filter before the rotary pump. Still wondering about bad gas though...
Stuck a flash light down in the tank and the gas level is at the top of the fuel screen and it looks clean down there. I'll check the fuel pressure tomorrow. |
