Got a Mastercut riding mower with a 12hp Briggs I/C engine. The factory number is rubbed off its tag. If anyone has one of these please post the factory number.
The maker tag has AeroIndustries but I think it was made by MTD. I'm not sure when MTD tookover AreoIndustries so it may be AreoIndustries made. If you have a Lawnboy or some other brand with the same features then it's MTD. The year is around 1985-1989. The closest I've found so far is an Agway 300 which is an MTD #137-332-019.
The engine on this seems shot. The compression is 30psi. I can turn the flywheel easily by hand through the compression stroke.
UPDATE: Got it started and it runs very well. Cut a big section of lawn and no engine sag. Went up a steep hill cutting and no sag. The engine seems fine. ?? Ran it up and down the street and it ran fine.
