ok i have a y7 with 450 ccs with resistor box walbro fuel pump running about 7 psi. im tuned with safc2 and i cant get it to rev past 3000 rpm it almost sounds like a rev limiter but the safc doesnt have that feature or does it?? it is stiil way rich i think and i have the fuel cut back to -50 in all rpm ranges any help would be appreicated

 

did u touch the timing at all?

 

Any cel's? sounds like a code for the dizzy...one specific one that makes it seem like there's a rev limiter and runs pig rich.
