richardo1967  I've tried  but the the only way i can get it to run clean is by playing with the fuel shut-off

--- End quote ---

 Idle check is blocked off at open throttle and has no effect on top end performance. Top end delivery control is done with a high speed check and the can be tuned with jets and shims.

the port i'm asked about is after the spool and before the injector lines and leak here will affect the fuel curve , on methanol i didn't have a problem but the customer wants to run gas.

dreracecar:
Why did you not mention the GAS part????
Idle slot is much smaller for gas and would be better off changing to a "GAS" spool then to try an add gimmicks

jeff/21:
been changed #54
