I'm using a 2150 MC, Ive tried two other carbs a 2100 and ford ranger 1bbl with same results
I also epoxied the tiny hole in the corner for the choke, because I'm running a manual choke not the stock vacuum one
Already tried paper gaskets between the intake and carb
I think since with these spacers you can see the in print of the carb you last had on and me trying on a 2150 when a 2100 was on there originally caused the imprint to get dissorted and made a big vacuum leak.
Whats best the spacers with the two holes or open ones with no throttle plate holes
and there expensive $80 for the average one from summitt
Also finding a rubber spacer seems impossible looks like only racerwalsh Carry's them
Il try a Phenolic spacer but first want to be sure that its the casue.
