Picking up a 1981 G1 for next to nothing? Yes or No?

I am 100 percent sure this is a 2-stroke. I thought all G1's was two stroke? i need to read up on that. I will get home tonight and try cleaning out the fuel system really good. I am picking up some boat seats for it this week.

You are correct! All G1 are 2 stroke. I was haveing a brain fart moment!

I would just plan on changing out those crank seals.

From the web:

The Yamaha G1 had a 2-stroke engine. The G2-G9 models had a Yamaha-built 4-stroke 285cc 8.5 hp, single-cylinder engine. It has been said to have been a basic copy of Yamaha's motorcycle engine. After the 285 grew long-in-the-tooth, a 300cc was built on the same design platform, but it pumped out 9.5 hp. Next came a 301cc engine built on a new platform. It produced 10.0 hp, and is the design platform for the next 357cc engine. The newest engine of the Yamaha engine lineup is a 357cc, named the 357F, 11.4 hp engine. All of Yamaha's engine except the G1's are 4-stroke, overhead valve (OHV) engines. All Yamaha carts except the YDR ("The Drive") have a Dana/Spicer rear transaxle. The YDR uses TEAM clutch systems and a TEAM transaxle with its brakes housed in the casing, eliminating drum brakes on the two rear wheels.

Here is a link on cleaning that fuel filter:

Here is a link on something to check out on the carb:

The carburator is very similar to those found on a mower, so if you have cleaned one on a mower you should have no problem.

Thanks for the info. I will tell you that i wanted to work on this cart today but i didn't get the chance. My schedule changed with work and i ended up having to work 3rd shift. I did infact get the cart out and drove it around. It was running good like normal and then started putting around like it normally does when it gets warm. Like it floods itself. I hit a bump though while it was doing that and it took off like bandit. Then started doing it again. I think this issue might just be fuel related. I am going to work on it tomorrow morning hopefully! I will be sure and update this thread when i do.

I think this will really help you work on that Carb.
