The Stovebolt Site Forums The Parking Lot '60-'66 Trucks Offenhauser Dual 1bbl intake

is anyone on here running dual 1bbl rochesters on an offenhauser intake? If so how has it been for you. Im waiting for my tax return and when that baby comes in im going to be replacing the intake, exhaust manifold.

also i found out last night while rebuilding my carb that the float was bent and worst of all while removing the throttle body from the float bowl i was hearing a rattle, i thought ok maybe a check ball never came out, turned it upside down and nothing. so i continued taking the throttle body off and low and behold the two TINY screw holing the butterfly had somehow snapped off right at the top and the butterfly was somehow still resting on what was left of the screws. any ideas on what i can do with this as well please let me know.

cheers

The thread on the screw should be 6x32. New screws come in the better rebuilding kits.

The old screws may generally be removed by using a diamond burr from the head side to make a centered pilot hole, and then use a very DULL drill bit to "hang" in the screw. When the bit hangs, the screw will then screw out the opposite side.

Floats are also available.

(Opinion) there are other carbs that work better.

Jon.

Opinion seconded.

ive been lookin at carbs, you guys have any suggestions? Ive been lookin at the weber

I am running the Carter-Weber carbs on my 261. Happy with the result. Bought the carbs and linkage from Langdon and mounted them on a Fenton dual intake.

I'm partial to the Holley model 1904, which is primarily an International and (dare I say it? Ford carb. It also saw use on some GMC engines in the late '50s/early '60s. It does require some alteration, as the throttle lever is backwards for a Chevy, unless you can get lucky and find the GMC inline 6 version. Easy to overhaul, and the jets are the same as the later 2 and 4 bbl Holleys, so they're very easy (and cheap) to find.
Another good choice is the Carter YF. You just have to watch what it comes from. There's some out there that are Ford variants that will run way too rich on a Chevy, some rebuilders will stick them in boxes marked for the Chevy carb.

For a Stovebolt 6, I think its really hard to beat the Carter W-1 in this application. Easy to tune, well matched to the engines, works well with modern ethanol blends. http://www.thecarburetorshop.com/
