1988 ezgo 2pg reed valve gaskets
I've been working through the many issues on this new to me 88 ezgo. I was able to get it running, but it runs rough and backfires. The compression is good, 120ish and the PO replaced the top end. Listening to the advice of many of the great members of this forum, I pulled the muffler and it runs better but doesn't have much power and still has a back fire. I pulled the carb again and check the reeds. There was on gasket beteeen the carb and the reed plate and below the reed valve were two more gaskets. They were all saturated with gas. Can anyone tell me whether it needs both bottom gaskets or just one on top and one below? Should I add any sealer? I am guessing that that this is the cause of the backfire. The carb is one of the knockoff bv24's from ebay, but it seems to working. I am Hoping it's just gaskets, but will put back together and find out. Any thoughts would be appreciated. I plan on having a muffler BBQ tomorrow. Thanks

Re: 1988 ezgo 2pg reed valve gaskets
When does it backfire? Does it do it at speed, or when letting off the gas, and stepping back on it again?
A spring missing from the throttle cable is the biggest cause of backfiring. Read this thread. http://www.buggiesgonewild.com/gas-e...djustment.html It holds the throttle plate fully closed until spark is introduced. You can rob one from an ink pen. The pictures show the spring slid over the end of the throttle cable. Another cause is doing the hei mod, and having the blue, and red wires from the pulsar swapped. |

Re: 1988 ezgo 2pg reed valve gaskets
Thanks Cart Around. It seems like it viva right from the start. When I loosened the exhaust it got better but backfires when I let off the throttle. I know a little backfire is normal on two strokes typically. Thanks for the tip on the spring. I have a whole drawer full of candidates to address that. I ordered new gaskets last night for the reeds and carb. They should be here on Friday and I can put it back together and give it a try. I did notice that while I was running it with the seat off and watching the exhaust there is a small hole in the weld on the top of the muffle which is allowing some air in. I could see the detonation. Pretty small hole but probably a contributor.
What are your thoughts on the reed gaskets? One or two? and should I run a gasket sealer in addition to the new gasket? Sent from my SM-G935V using Tapatalk |

Been quite a few years since I rebuilt my motor, but I’m pretty confident one gasket goes above/one below the reed valves. I did not use any gasket sealer.
