I have a B&S Engine (401417-0011-01-80052012) that is not currently running. I am trying to get it going. A little backstory is that this motor was on a 'kit' 3 wheeler type of ranch buggy from back in the 70's. It's a two seater with saddlebags and has the capacity to carry some small cargo that you might need on a ranch way before the days of UTV's. Anyway, I have it in all original condition, and it was purchased by my grandfather. A family member recently took the entire 'bike' to a shop. They shop owner spent a great deal of time telling us that it was really cool and fawned all over the item before taking it in to see if he could get it running. The next day he called and said "It has low compression, we can't get parts for it, but I'll give you 500 bucks for it as is if you want to just leave it".
Anyway, I have the thing myself and I need to verify if it in fact has low compression. My suspicion is that it's fine. I have rebuilt all manner of small engines and am equipped to handle this restoration.
1.) I need to get my compression tester, and I know how to use that, but since this motor has been sitting for so long (YEARS), how should I test the compression? I want to put oil in the cylinder first....but is that advised?
2.) What compression numbers am I looking for? I think the number itself is not quite as important as the two cylinders being close to each other. Either way, I need some guidance on that.
3.) In reference to the above question...Does anyone have a service manual in PDF form for this particular motor? I am usually pretty good at finding these online, but I have not located a service or repair manual...just the operators manual and IPL.
Thank you for all of your help!
