Fire problem ... maybe
Moparfan,
The carb that you stated, the 750 will only run on the front 2 bbls under normal driving conditions, and the secondary's will only start to come on @ about 2800 or higher rpms. Then at this point they are just begining to open. The primaries on a 750 are about equal to the small 2 bbl that the 318 comes with, about 375 cfm's, so it should work fine on the little engine. As long as it's a vac. sec. and not a DP.
