How do you match up a WD45 carb to a B manifold since the bolt spacing is different? Or are you suggesting to widen the holes to get it to work?

Would a WD Carb work since the early ones were the same bolt spacing?

I know a lot of pullers scream big carb big carb. You can get all air mixed fuel your engine can use even with the largest bore and stroke you can fit in the engine out of the carburetor that came with the tractor. With a few modifications. Some of the places I pulled every thing you could see with your eyes had to be stock. To get what I needed in a carburetor I did with the existing carburetor without changing the outside. It just takes some trial and testing. You can mount as big of carburetor on as you can find and still can not get any more fuel mixed air into the engine than you can get thru the manifold and valves.

If you're talking about the Centre County Grange Fair, he cant pull there anyways....lowest class we pull is 4000 pounds but The Antique Show at Penns Cave does as low as 2500. As far as alot of pulls around this area go by the pulling rules at the CPTPA webpage http://cptpa.yolasite.com/

He could always add about 1500 lbs of weight and pull with the 4000 class. Never know what might happen but he probably won't spin out.
