Anyone else having trouble with rubber carb spacers?
« on: November 28, 2012, 03:44:44 PM »
I posted a thread on here about my car not staying running etc....

Maybe its the rubber 1" spacer?

1st its warped not by much but it wont hold a straight edge and its also hard as rock is this normal or should it be somewhat soft/flexible/sink in?

Everytime I take the carb off its soaked with fuel?

Already tried RTV slackening the spacer to manifold and using a thick paper gasket on top where it meets the carb with the same results.

Also tried bolting it down as tight as I could get it without the aluminum snapping.

I choice to use the rubber gasket because of the 4 cylinder vibrations.

Is it the spacer?

How about a  1" aluminum spacer on a 4 banger?

I always use a Phenolic spacer. and use a gasket between the intake and the spacer and the between the spacer and the carb. phenolic wont warp, and it always runs a lot cooler than plastic and aluminum.
The fact that is soaked with fuel is not normal your carb may have a leak. what carb you have?
And the rubber gasket wont make a difference with the vibration.... 
Aerodynamics is for those who can't build engines

If ford pintos are not fast then why chevy's have to use there parts to make them fast?

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.
