fuel pump
I was asked a question this past weekend that I had no answer for , so I thought I would share it ,
I was asked , my compression is low ( 85) so can I get a few more months out of it by adding an electric fuel pump , I know it needs to be rebuilt but don't have the funds for it now and won't have for 3 or 4 more months but need the cart to work now . I could not tell him yea or nay , any opinions out there on this ?? |

Re: fuel pump
Fuel pressure wont buy you any time but you're really talking two different areas. Compression is in the topend and crankcase pressure/pulse is in the bottom that works the fuel pump.
It doesn't take a lot of P/P to run one of these little pumps and they still will pump fuel with low compression so the pump is working. Time to bite the Big Block Bullet!!!!! |

Re: fuel pump
If you could get it to run with one, sure why not use it. If it's a 2 stroke we are talking about, (I ASSume it is) the blow-by is going to really mess with the fuel mix trying to get into the cylinder. (probably the reason it won't run) I doubt it's going to work on one but if you had a pump laying around why not give it a shot. even if you don't have a pump you could come up with some kind of gravity setup just to see if it'll run.

Re: fuel pump
Are you sure the valves are adjusted right. see if many many times, people ask price on motor and the only thing wrong is the valves are too tight causing loss of compression. Just an idea.

I WAS thinking of getting myself a 2007 model ezgo 4 stroke ( 350 ) engine ,,but after reading all this posting about adjusting the valves all the time I'm not going to bother with the 4 strokes , on a briggs engine the valves may need to be adjusted maby once every 10 to 12 YEARS . Seems to be an ongoing thing with the cart engines . got to be a poor design . |

The newer cart/engines have harden valves so it shouldn't be an issue. |

Re: fuel pump
Got the old fuel pump to work properly , problem was in the origonal 'metal ' fuel line that came on the cart , it was /is evidently mostly stopped up , replaced with a new rubber line from tank to fuel pump , without going all the way across the cart then coming 1/2 the way back , and presto ,, it's working fine , still hard to start because of low compression but does start and run for now .
