Look like a work in progress, still running and pulling it's weight with the chores I see, best wishes in getting the things done you need to do yet :fing32:.
The numbers that I found on the engine were on the top on the cover. Some were unreadable but it was something like 148580 01 86121214...but I'm sure there may be a few wrong digits in there. I will check below the carb to see if there are any other numbers.If you can clean the blower housing where the model, type and code numbers are (usually below the carb), you would be able to tell what size and year the engine is, the first 2 numbers of the model # is the cubic inch displacement, and the fist 2 numbers of the code # is the year built, here is a link of what I mean, http://www.briggsandstratton.com/en...~/media/97C8707304E642BFA70617A820B1C403.ashx
Actually now that you say that, I believe the newer engines do have those numbers on top of the blower housing, there might not be any numbers near the carburetor. But from the looks it was manufactured on Dec. 12 1986.The numbers that I found on the engine were on the top on the cover.
