Re: 89 EZGo carb upgrade? (need towing power)
I used a carb off of a 88 2pg on my 89 3pg they are a couple mm bigger than the 89 3pg. I also advanced the timing at the breaker plate and had the head milled .030. My 89 marathon easily pulled my 3700 pound car though it did struggle to get it in the trailer when I broke my pinion in my car. With the bumped timming and higher compression I mixed a little VP No2 with 92 to stop pre ignition in the cart. The marathon does a much better job at pulling the car with the polaris 440/ 4 stroke trans axle thats in it now but it did take a bit of work to get it to a point to where I am happy with it.
I would check the float level in the carb you have and maybe even set it a tad high and see if that helps. I would also check to see if the tank is venting. When it starts to peeter out, pull over and open the fuel cap to see if it has excessive vacuum in the tank. Check and clean all the carb vents and bleeds too.

Re: 89 EZGo carb upgrade? (need towing power)
Just thought I would update and say thanks to all for the suggestions. I got a new belt from NAPA. It was slightly shorter and about .040 wider thant the worn out (original?) belt that was on there. I didn't notice much difference, but it doesn't slip anymore on take off.
I also took some ignition timing out of it. I had to make my own ignition system for this cart after the original reluctor wheel got ground down by the pickup (presumably from the crank bearing being worn out on that side?). I think I had the timing up over 40 degrees. Backed it down to about 30, and she'll just ping a little when loaded hard, so I mixed in a little 114 leaded and it seems to be running great. Finally, I added a vent to the tank. I assume the cap is vented, but maybe it isn't enough. With my hand over the fill hole and the electric pump running for about 30 seconds, there was a definite vaccum on my hand. I had tried running without the gas cap the first time I had this problem, but since then I have reringed and ditched the mechanical pump, so might have been two entirely different problems. |
