07 Yamaha G29 golf cart has a bad TPS. With a bad TPS, would the main solenoid still operate? Reverse buzzer is not working as well. Trying to determine if the controller is bad.

It is most likely related to the rings, but running it would unstick them very fast if they were stuck. It's possible that sitting let rust develop in the cylinder walls and there may be some grooves in them now. They could also just be really worn cylinders. They make some oil conditioners which I wouldn't recommend on a car, but might work fine on a golf cart. I can't recall the name, but it was in a silver can, maybe called engine restore... You could always try that before resorting to a rebuild.

When you removed the batteries, a certain procedure MUST be followed. Key switch off, switch to tow position and shift lever in reverse. You must wait until the beeper unit sound dies out then remove the wire from the most NEGATIVE cable. Place in Neutral before installing new batteries. There is a specific sequence to putting the batteries in an EZ-GO cart. Failure to follow this procedure will kill the controller. The Key switch must be off and the maintenance/tow switch MUST be in the tow position when connecting the batteries. Any of the above will cause the controller to fail, due to improper discharge of the PRE-Charge capacitors.

Very important... valves get out of adjustment and are easy to set. This is where I would start FOR SURE. Check out www.buggiesgonewild.com and an example of how to do it on EZ GO 295 http://www.buggiesgonewild.com/ezgo-gas-tech/1196-ezgo-295-350-engine-valve-adjustment.html

Hello
The serial number of the Golf cart does no good to ID it. I need the model number and the displacement of the engine as well as the number of cylinders and what year it was produced..

Hi and welcome to FixYa, I am Kelly.
The new carb. fuel mixture adjustment screw should be very close to the setting needed to operate the engine normally. You should not have to move the screw more than 1/8 th turn in either direction from the current ORIGINAL setting.
You mentioned the engine smokes really bad. Several things cause a smoking engine:
1. Older engine
a. Piston oil rings stuck to the piston skirt or rings worn out
b. Piston wear
c. Cylinder wear
d. Valve stem and valve guide wear
e. Valve head and valve seat wear.
f. Crankcase breather clogged
g. Overserviced engine oil.

Perform a compression test on the engine. You should have a minimum of 120 PSI pressure. The higher the pressure the better. If the cylinder compression is under 110 PSI the engine needs some serious maintenance.

I can not emphasize enough that the new carb needing any major adjustments is a symptom of other problems within the engine. Like I mentioned earlier if you have to make a fuel mixture adjust more than 1/8 th turn in any direction from the original setting something else is wrong.

IF by chance someone got over anxious and has moved the fuel mixture screw start at 1.5 turns from just barely closed. I am surprized that the new carb did not come with a plastic cap over the mixture screw.

Thanks for choosing FixYa,
Kelly
