Be careful to not get to close to the hole for the case pressure. I used a dremel to oblong the hole. You also have to countersink the plate on the hole for the case pressure, It is molded with a rounded edge, so tapering the hole allows a flusher fit. Only question I got about it is, Is it going to matter that my plate's intake hole is slightly smaller than carbs? Other than that, I'm happy with the results.

PS, I do plan on cleaning that carb and stuff once I'm done dinking around with it. I've got a buddy that is samll engine mechanic, and he suggested using some of his 'Tama' (I think that's what he said) sealant around the plate/block mating surfaces. He said that stuff works better under gasoline exposure than silicone.
