G1 Yamaha with fuel delivery issue
I have read a number of post on this GREAT forum, but still having a problem with my Yamaha G1 cart starting/running at all. The electronics are fine, if you hit the carb mouth with starting fluid it runs.
Here is what I've done:
The engine still would not start so I pulled the fuel line from the carb and watched for fuel delivery while the engine was turning over. Not much fuel was coming out. So I did this:
Engine still would not start, so I did 3 compression tests and best result was 105 psi. Is this too low to create enough vacuum for the fuel pump? How much would new crankcase seals improve the vacuum? Any help would be appreciated. "Go Fast or Go Home!" |

Re: G1 Yamaha with fuel delivery issue
crank case seals are the next thing to check. Jack the cart up and push on the gas pedal and let it spin up a bit. while its doing this spray some wd40 around where the crank case seals are. If the RMP changes at all then they are wore out and need replaced. This is a VERY VERY common thing and its pretty easy to do

Re: G1 Yamaha with fuel delivery issue
The cart is not even running so he won't know if the rpm changes!
Air pressure (put the end of a compressor hose- just about 3-4 psi through the tank) will help push gas out, initially. Then press gas pedal to start the cart. |
