G1, idles great, runs rough, runs better when warm
Im new to posting but have spent several days reading the forum for advice. Thanks to all who have posted about g1s. I just bought the cart and was told its an 81 Yamaha g1. It's stock. I use it to drive around a large property daily several miles. The problem is the cart seems to cut out under power. If I choke it. It will power right back up. So it's choke on, choke off, repeat. It idles great. Starts instantly and runs rather quick. I've cleaned e carb, and sprayed starter fluid around the seals. The motor didn't sapped up with the starter fluid so I presume the seals are okay. The plug is brown so mix seems ok. Any ideas? Thanks in advance for any help

Re: G1, idles great, runs rough, runs better when warm
First thing is first.....check air filter, check fuel, check oil reservoir. If cart has been sitting change oil and fuel, and fuel filter. Check fuel pump, sometimes those get gunky. If all that is good, look at the carb. Take carb off and clean really good, blow out with compressed air, let dry and reinstall. If that doesn't do it, it's probably the seals. These 2 strokes just need a good rebuild after so long. If you can keep it running without too much trouble, run it the way it is. You shouldn't hurt it as long as you aren't towing, pushing, or racing it. |

In addition to what slim said...these carts in particular are extremely famous for not running well if there are any air leaks. This means check all hoses and make sure air filter box/housing are air-tight and sealed or this can occur...
