Large ID, straight through bore carburetors, that have no vacuum signal to draw the engine's necessary fuel, can be made to work extremely well when there is adequate tuned pipe pressure available. Tuned pipes with inadequate volumes, which result in short, large ID stingers & low internal pipe pressures, will not work in this application. This applies to both nitro & gas type engines! The carburetors shown are mounted to both nitro & gas engine types. They are 100% maintenance free & have extended working part lives. The carburetors shown range in size from .625" bore to .725" bore & all are straight through designs.
