I have a Toro 22-inch self-propelled mower model 20334 with SN beginning with 4068. If anyone knows the size of the bolts holding the electric starter assembly to the engine block, could you please tell me? I’ve lost one while mowing and even the local Toro dealer couldn’t tell me. I just tried 1/4-20 and it’s too small (diameter). I’m thinking it’s probably 3/8 but I can’t find docs saying that. I can’t get to the other one w/o taking a lot of things apart. Help? #Toro #Mower #SmallEngine
AHA! The electric starter is listed as a Briggs & Stratton part since it’s part of the engine, not a Toro part. Progress. It’s B&S part number 799045 and I found a YouTube video stating “3/8 inch bolts.”
Well, 3/8” is too large but 1/4” is too small. I’ve no idea what to do next other than break off a wooden dowel in the hole. This is ridiculous.
Closure to the bolt saga: The missing bolt was indeed 1/4-20. It I got the wrong thread the first time, and the YouTube guy saying it’s 3/8” is obviously wrong. I was finally able to remove the other bolt and took it to the store to match it. Only took three trips and about $6 for one bolt. Such is my life.

This should hopefully point you in the right direction.

@inclinus Thank you. That’s where I started but there’s no mention of the starter assembly.
