Well i told this hissing is completely normal for a carb. It wasnt making that noise last time when i was puttimg in seafoam so thought it was abnormal.
change that switch![]()
As i said it starts on 12 volts directly from the starter. The in the run position on the switch it runs on the risister wire from the switch. No that high compression 472 will nor run good on any fuel under 90 octane 91 is the requirement.
I see what your saying. I may just have to pull it out, take some pics and compare them on the internet.Some one as all ready done the cut and splice.
