So I have this golf cart that I've been slowly working on. It will fly on flat land but sucks a butt going uphill. I talked to a guy that did repairs yesterday and he said the rings are probably gone. Thus my compression is no bueno and can't pull enough fuel into the chamber when under heavy loads. he suggested I get a small electric fuel pump to put on it to keep fuel pressure constant. He said I need to get the lowest flowing fuel pump I can find. I don't really want to fart around with a parts monkey to figure this out. Do any of you know of one I could use? He said something like 1gal/min or less.

If I can get it going I'll take a video of me going over some sweet jumps with an NC4x4 flag. Thanks.
 
^^ thats what I'm thinking, then you can just adjust it as necessary to figure out what works.
 
Flow and pressure are 2 different things....
 
well, I'm just going off what the guy told me. I figured he worked on them so he would know. Basically, he said the pump would keep the carb full of fuel. Instead of being starved when under load. it made sense to me at the time. I figured a small fuel pump would be cheaper.
 
Look up "MIKUNI FUEL PUMP". They are used in some snowmobiles and also used to convert the old Evinrude "pressure tank" outboards to standard tanks. Basically you come off an exhaust port from the cylinder to the diaphragm on the fuel pump. The pulsing pressure moves the diaphragm and runs the pump. Seems like it was rated around 3 gallons an hour, but I could be wrong on that. Something like that might work for you and they are only around $25.00 new.
 
Why not just put new rings in it?

I don't have the time for a brea kdown and rebuild. I would like to though. The entire rebuild kit is like $300.
