B Manifold Question '41 B

HumptyD · Jul 7, 2013

Just bored to .045 over and found some new old stock all fuel pistons. The manifold needs to be replaced and was wondering if I can switch to a gas manifold instead of the all fuel. The old one is unusable. Going to be a parade tractor and for pulling around the grandkids in a wagon.

A gasoline manifold from a later B should work just fine. Also,
the DLTX-34 carb should run good if its clean, and if wanted,
the main fuel nozzle from a gasoline B can be installed.

I wish I would have posted the question earlier because I just ordered a new jet for the carb. But if it still works, I'll use it. Had to buy a used used 34 since it came with a 10. Just blasted the carb and will be rebuilding it later this week. Our plan is to get it running then blast the rest of the frame before we repaint. Hate to do all that work and painting only to find out it doesn't run

Another question: If I use a late B manifold, do I need to make any other changes with intake or exhaust? From comparing both, there's a slight difference in the angles.

I put a late B one on my 1945
Found out the intake pipe didn't line up to the air cleaner. I
put a plug in the top bolt hole and redrilled it about a hole
over and it lines up.
For the exhaust I had a pipe made at muffler shop and
rewelded my flange in the right spot.
