Given what it takes to convert a gas carb to alcohol, it's a lot more than jets, and I'm not sure you can reverse the process, I've never tried. There are all sorts of restrictions you drill out to go to alcohol, you'd have to close them back up. It'd take a 1/2 hour or more to detail it here.

They are two different beasts: for starters, metering blocks are different and need to be changed. Inlet valves and bowl are different. Bleed orifices are also different.

Thanx for the replies---did not want to get totally involved in going that route either---had a chance to pick a few basket cases cheap just do not want the hassle of trying to make one work--thanx Comp 387

I have a 1050 Pro System Alochol Dominator I'll sell you. It has about 70 pass, most of which were 1/8 mile. Looks and works like new. New ones go for $1,100.00 let this one go for $750.00

Boosters and booster pins, and both metering blocks. How cheap?
