My 1993 Yamaha G9-A Golf Cart
Hello! I only use my 1993 G9-A golf cart during the summer for work around the house and rides for the kids. Actually, it has been running quite well for its age, but I feel it needs a good going over to reduce the chance of a breakdown while out and about. I did change the oil within the last year and try to keep the air filter clean. One problem I've had for a couple of years now is a carburetor that really spits and sputters when I am first running the cart. I typically have to keep one hand on the choke knob and pull it off and on for awhile until the engine starts running smoothly. The carburetor obviously needs work and, though I'm somewhat handy, I'm not sure I'm capable of rebuilding a carburetor (?)....at least not without some kind of kit and instructions. Something else I may need is a drive belt and starter/generator belt. How can I tell if I need new ones? These are just a few of the questions I have regarding my golf cart. I guess I'm just not sure at what point I might be throwing good money after bad. I'd like to think that I have at least a couple of years left with the cart. If anyone can give me some advice, I'd certainly appreciate it. I'm kind of at a loss. Thank you! justjeffb Rebuilding the carb is an option. If you consider buying a new one I would make sure that you buy the brand name one and not a cheaper generic. Don't forget the usual maintenance stuff like a fresh air filter and spark plug now and then. The starter generator belt is like a belt on an old car or truck. It works as long as it's not broken but signs of age such as cracking or cords showing mean it's a good idea to get a new one. The drive belt has specs in the service manual as to when it should be replaced. As it wears it will change your gear ratio over time but I've never seen one break. I replace it whenever I have to do overhaul work on the drive or driven clutch. Pilot Dane, Thanks a lot for your input on my golf cart. I'll have access to the cart in a few weeks and will hopefully put some of your ideas into affect. Thanks again! justjeffb If you will have access to the cart in several weeks it makes me think you don't use it very often. If it has sat for long periods you may need to think about new fuel line and possibly cleaning the inside of the fuel tank. If left to sit for long periods varnish will form. Cleaning the carb can remove it and hopefully get your cart working again but as the flakes of varnish break off the inside of the fuel tank and fuel lines they can clog the jets in the carb. Also if you are looking for general reliability and maintenance stuff take a close look at the rear/driven clutch. There are some ramps that should have plastic buttons on the top. Make sure you have them on all the ramps. They are a wear item and help the clutch shift smoothly. Also look where the clutch meets the transmission. You should see some gap between the cluch's sheave and the transmission. There is a little clip on the shaft that often fails allowing the spring to shove the sheave up against the transmission causing it to rub metal on metal. It's easy and relatively inexpensive to fix if caught early. Hello again! It's obvious I had the right person respond to my inquiry as it's very clear you really know what you're talking about....hence, the group moderator position, I guess. I definitely have some work to do on my golf cart. I actually use the cart about four and a half summer months per year. It's at a summer cabin that I won't visit until late May. Being dormant for 7-8 months a year, varnish getting into the carburetor jets is a very real possibility! One other concern that I forgot to mention is the timing of the carb. Is there a website or online video that might assist me in adjusting the carb? Along those same lines, are there websites or online videos that might also help me with some of the other concerns you've talked about? I, like most people, learn better by being shown do something. Thanks again, Pilot Dane! justjeffb The carburetor is not bad to work on if you've worked with small engine carburetors before. When in doubt take pictures at every step so you know hook things back up or re-assemble them. For needles I gently screw them in until they seat. Counting the turns and writing it down. That way when you reassemble the carb you can screw the needles in and then back out x number of turns and be back where it was before. Short of going crazy buying carb parts for just in case you will need a carb cleaning solvent to soak the carb in for several hours or overnight and a can of spray carb cleaner. Gaskets would be useful if the current ones tear when you remove the carb. If your cart sits dormant that long you should be draining all the fuel of the tank and carburetor before setting it up for winter. Another option is to run aviation gas (100LL) in the cart toward the end of the season. It contains no alcohol and does not break down and form varnish like auto gas. A worst but workable option is to use a fuel stabilizer with auto gas. Thanks again for all of your help, Pilot Dane. I'm looking forward to working on my golf cart and getting it running well again.....as well as a 1993 golf cart can be expected to run! I certainly know where to go if I have questions along the way. I appreciate all of your help. justjeffb
