Not quite sure which newsgroup to post this in, but since I am building
a mini chopper, I thought this would be appropriate.

I just purchased a 6.5hp Briggs motor, model# 121332 from harbor
freight . It is a single cylinder OHV engine. The first thing I
noticed is a big note right on the box that said "For go carts, use
only model # 136200". Here is the link to the engine:

I downloaded the manual for this 130000 series model, and it is quite a
bit different. The 130000 sereis is a single cylinder L head engine.
The cylinder sits straight up and down, vs the 120000 model where the
cylinder sites at about a 45 degree angle from the base.

Does anyone know why B&S recommends to only use this136200 model for go
carts?

I don't see any problem with using the 120000 model engine I purchased,
but I just want to make sure before I fire it up and start taking it
apart to fit it into my chopper.

Thanks for any info.

Most likely lubrication- the 120000 is recommended for fixed
applications (pumps, gensets) and it's possible it won't lube the
valve train if it's bouncing around a lot.
Also, the 120000 looks to be a fixed-speed engine and may not have
enough bottom end to get a kart moving or have too high an idle speed
for a Comet clutch.
