I second CJP'S 29. B38 is ideal or B37 if your generator hits the horn.

Those wanting to run a B series industrial belt (like B38 or B37) might like to know that the Bando Power King series are still fully wrapped belts, and can be made to look "period" by just daubing a little black over the most modern parts of the markings.

I ended up ordering the B-38 belt which was delivered today. I plan to install it tomorrow. I was definitely running the wrong belt from Napa. I knew it was too long because of the generator being all the way out but I didn’t realize it was the wrong width also.

I had a big scare the other day which lead to my post about belt size. I drained the engine and radiator in the doodlebug because I wanted to fill it with 50/50 antifreeze and move it out of the garage and down to the shed for the winter. After I filled it back up, I drove it down to the shed, set the parking brake and jumped off. When I noticed the water pump wasn’t turning I flipped the ignition switch. After drying off the belt and attempting to adjust the generator a little more I went to start it back up. It made a fairly loud crash sound and it wouldn’t turn over. After double checking my power I grabbed a screw driver to try and had turn the engine and it wouldn’t budge! I thought I locked it up, but didn’t know how. It was a somewhat mild day, maybe 40 degrees and it was only running for 5 minutes or so. After talking it out with my neighbor we decided to pull the starter which thank goodness was the culprit. Turns out a mouse had built a nest in the start and caused it to gum up. Talk about a giant relief! It was such a gut sinking feeling to think that I seized the engine I just got running. Needless to say, it was a wake up call- ordered the right belt and I’ll be purchasing a new oil filter since I’ve been limping the other one with a screw and rubber washer to plug a leak.

Thanks for the replies!
