Default Re: 91 ezgo low rpms

I did hold the throttle open by hand,
best I can remember the valve adjusters
was all close(the threads) I will have
to check the over charging thing.
I was grabbing at straws and thought
maybe the ignitor was going bad and
since it is mounted on a plate along with
v/r and solinoid it was more easy to just
change the whole plate

Try that teaspoon of oil also in the low compression cylinder and see if it ups it when you re-test

Your results show the piston rings and possibly cylinders are worn and a rebuild is needed.

well I figured as much but will
this keep the engine from reving
up enough to pull the cart.
it was running, the carb went bad
(had to choke it like crazy and run
it with the choke half on)all i did was
replace the carb & fuel pump, now
it will not rev up enough to engage the
clutch.

Yes, your compression is low enough where this engine won't run very well. 115 pounds is 55 pounds less than what I would want to see.

If I were working on this engine I would not put any more parts on it until I removed the engine and rebuilt it. It will perform like you wouldn't believe after getting that compression back to where it should be.

If rebuild is done correct this engine should have 170 pounds of compression on both cylinders.

I don't know where you got the new carburetor and fuel pump but if I had to guess I would say ebay or amazon ?

I am just giving you my opinion. Good luck

ok thanks for the advice I will
look into a rebuild when the
weather gets a little cooler.
The barb and fuel pump came
from a local ez-go dealer.
thanks to every one that responded.

I wish I could help you more but with the info you give me I don't see anything other than getting that compression back where it needs to be.
Good luck.

I had same problem last year. Not knowing exactly what was going on I adjusted valves, checked comp and rebuilt carb. I found the needle valve had slipped off the float assembly which was causing too much gas at start up. As you say I had it on jack stands and ran fine with no load but under load would not rev up. I also found the clip that hold throttle cable to governor lever was loose and not secure. Fixed that and then cart ran great. I don't know which item fixed cart but that is my experience. Good Luck, Tom
