Dominator Carb in Supergas

Squirrell · 10-05-2013, 04:39 PM

Hi Guys, Finally got the Beretta home and have had a quick look at the Dominator carby. I have not pulled it down to see what jets and air bleeds etc.are in it yet but will do that in the next couple of days. The part no. on top of the carby reads, 12R-9027B. there is also another number 1713 on the top. is this a Gasoline carby or a Methanol carby ?.

P.S. Johns Racecraft did not have any information on any cars built at Smith Brothers Chassis.

Thanks again for your help, Squirrell.

That should be a non-HP 1150 casting, the list number on top should be a 7320 or 9377 unless it was a custom built carb using a bare casting. If you can post a picture of the main body side of the metering block, I can tell you if it's 2 or 3 circuit. If it is a stock unmodified carb I would suggest getting it reworked, with the right mods it will work fine on the throttle stop. I have a pair of the old style 9377's one on gas, one on E85, both work fine on the stop. It should look like the 1050 in my picture below.

Hi Guys, here are some photos of the carby.

Can anyone tell me if this is a petrol carby or methanol carby. I did not find a listing for it on the Holley site. I have emailed them with the same questions. Thanks for your help, Squirrell.

Patrick

is there any numbers stamped in on the other side of the carby

the 12R number I believe is a casting number

It could be set up for alcohol based on the fuel bowl extensions.

Hi Rod , I could not find any numbers on either side of the carby. There are some numbers on the throttle arms, 1549 on the primary arm and 1480 on the secondary arm . I sent an email to Holley and they asked the same questions. Cheers Patrick.

Pull a bowl and look at the jet size. I'm inclined to believe it's methanol as well with the bowl extensions, but I have seen someone build a gas carb with a secondary extension... not what I would use on either gas or methanol.
