sms986 Posted June 18, 2013 Report Share Posted June 18, 2013 I have a 1999 banshee. a few mods but mainly stock. wiseco top and bottom end, bored .030 over to clean up the cylinder, and dg pipes. It will choose which carb to run on and won't idle. sometimes it will run on both carbs sometimes only one. when I go to ride it, I stick it in gear and it is absolutely gutless. I open it up and once I hit the higher rpm,s it slows back down and boggs until it shuts off. Then it will start up again. I switched the carbs to see if that would make a difference and put a longer choke tube on (it wrapped up over the carbs and onto the other side. it ran for a while with the same issues then wouldn't start at all. I then decided to tear into it and here are my findings. comp is 115 and the plug is getting the charge it needs. I took the plugs out after running it and they were soaked. tore the air filter off and the boots were both soaked with gas as well as the reed valve boots. It's flooding horribly. needles are at 3rd clip, 200 main jets and 25 pilot. float is set to 22 mm. there is a small visible ring around the rubber tip of the float valve needle. I'm assuming that's the issue but are there any other ideas? Quote Link to comment Share on other sites More sharing options...
hoppedupandcutdown Posted June 18, 2013 Report Share Posted June 18, 2013 Sounds like it to me, that's the first I'd replace. Maybe the seat too. Does it overflow the carbs out the vent hoses, not running but with the gas "on" ? Quote Link to comment Share on other sites More sharing options...
sms986 Posted June 18, 2013 Author Report Share Posted June 18, 2013 When I turn the gas on it's a fight just to get gas into the carb. I have a clear tube and I can see that there is an air pocket not allowing gas to flow into the carbs. after a bit of messing around I get gas in it and it will drip out of the vent hose from the bowl but not very fast.

sms986 Posted June 21, 2013 Author Report Share Posted June 21, 2013 Okay so I put the carbs together and set them upright on a bench and let gas flow into them. Let them sit overnight and came out in the morning to gas all over the table. There are 2 holes on the intake side. The one on the bottom is leaking gas. What causes this?

hoppedupandcutdown Posted June 22, 2013 Report Share Posted June 22, 2013 The needle and seat shut off the flow of gas into the carb, the float raises it to do so. That's it Quote Link to comment Share on other sites More sharing options...
