I didn't trust just the paper gasket to sit flush and seal these channels. The problem with these channels are they start inside the mounting hole and half of it is still exposed when mounted to the carb spacer. I would think this would lead to a vacuum leak and didn't want to chance it so this is what I did.
1) took the gasket from the 1101 carb and traced it onto some 16 gauge steel.
2) cut the steel following old gasket outline.
3) once my steel was cut I then traced that shape onto some do it yourself gasket material I picked up from Napa.
4) I cut out the homemade gaskets. One for on top of the steel, one for under the steel.
5) I took the new gaskets and applied them to the steel. They were self adhesive so this was pretty easy.
6) I sanded down the edges and center hole of my new contraption.
7) I then drilled the holes for the studs to go thru and mounted everything up.
8) car fired right up and is running better than it ever has since I bought it.
The 1101 carb now has a pretty solid base and the whole thing is sealed. I think that just using a gasket may have worked but I was afraid that the paper would break down in those channels and create a vacuum leak. I am hoping the way I did things should last at least until the carb needs to be rebuilt. Anyone see anything wrong with what I Did?
