Default 2002 txt 295cc runs till warms up

would not start reset valve clearance .004 changed coil, now takes off like a rocket runs till you let off gas or stop. then starts hard or have to let cool off to get going again. think its pulsar coil. checking to see if anyone has an other ideas. thanks to all or any that can help I am good with small engines this is the first golf cart I have played with. new to forum thank you.

How's compression? Good fuel flow? Have you grabbed a service guide out of the tech section of this site?

I have pretty much exact same issue. I've changed everything but pulsar and generator. Do you happen to hear a chatter noise?

Had a similar issue on a Honda 390cc engine. stumped me and my brother (small engine mechanic) so I relented and asked the old man to look at it...
Of course he found it.

It was the spark plug! It had a hair line crack and when it got warm the spark would jump to the outside of the plug instead of across the electrodes. Neer heard of that before or since but it ran great till warm. Let it sit for 10 mins and it would run again, until warm.

+1 on plug
+1 on possible electrical issue
+1 on any clatter from top end

Another thing to try.
Open up your valve clearance to 8 or 10 and see if it runs after it heats up.
Should have chatter in top end and is not really a solution just a test procedure.
If it does run Since it would not run at all before now when hot it does not would suggest a failure in the valve train.
Bad guides, improper valve seat, mushroomed / worn valves, possible cam bearing issue.

I hear a bunch of clatter when mine does it. What does that usually mean?

Can be a lot of things.
Chatter can you take a video?
Can you tell where the noise is coming from? Top end bottom or clutch?

Chatter i mentioned above is from loose valve clearance hammering everything or from bad parts rattling around. Loosing up clearance to make sure something that is getting hot is not holding open the valves loosing compression.

Chatter Could also be detonation from carbon or spark plugs.
Detonation from ignition issues. Ie coil ignitor or pulse coil.
Detonation from rich / lean mixture.
Erratic rpms causing the clutch to bang around and make racket.

it may or may not be this but i will not run a large fuel filter on my golf carts. i use a small motorcycle fuel filter because my carts will vapor lock with those huge automotive filters. my cub tractor is the same way. they run great when cold but in this heat they make for a pain.
