SH CArb questions

GordoSD · Jul 17, 2010

Rusty Farmall shouold nail these. Doing a carb on a very late SH. The bolts that hold the two halves together are hex head with the center dot and three hash marks going to outer edge. Are these correct? All I've seen are the tall head screws.
Venturi is 23. Is that correct for flat top pistons?
IT ran OK before I removed it but the heaviest load I ever put on it was a hay rake.

I have never worked on that carburetor but it sounds like someone has replaced the screws with grade 5 bolts.

Should probably have 12x24x7/8 screws.
And as for the 7/8" length they may be very hard to find.
Get 1 inch and cut them.

Yes for a late model SH the bolts could be original. 23 venturi is the original size.

If the bolt head looks like this, IH used them.

Gordo, posted a bolt head picture on classic. Se it didn't show up over on modern.

Yes, those are the correct fasteners. 1/4" x 20 hex head.
