Correct engine for Allis B-1

Recommended Posts

My B-1 has a 8 HP briggs in it. I'm pretty sure thats not original. Weren't B-1s 7 1/4 HP? Is a 19D the only one used in a B-1? Got a steam engine show coming up and I'd like to keep an eye out for the correct engine to get back to original. Thanks

Yup! it had a Briggs 7 1/4. Good luck finding one, I've been looking for over a year. There has to be some out there some place. I went through my B-1 about two years ago figuring I could find an Eng. pretty easy.Wrong!! I hope you have better luck.

In my opinion, the correct size is whatever you have that will fit into the tractor. I just went to a steam and gas engine show this weekend, and actually did not see any garden tractors, even the "so-called" restored ones, that were 100% original. Even the people who say their tractors are restored to original condition usually always change something that they did not like about the original tractors. Just like an "original" Simplicity 700 that I looked at this weekend that was painted a later model orange instead of the original red color, and had a rectangular fog light mounted in the middle of the hood instead of an original guide light. To him it was original, to me it was no different than mine. Mine is not original color, and mine has a 14 Hp Kohler under the hood. I do not do original restorations. Originality, as long as the tractor has not been hacked up, does not mean much to me. None of mine are original, but none of mine have been complete, operational, tractors when I got them. Most were re-created from parts that I rescued from the junkyard that someone else was going to throw away.

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁
