Just bought a 86 yamaha xt 600 from auction. The bike runs but is very hard to get started. It didn't seem to want to stay running after the ether burnt off either. After the bike was turned off it dripped gas as well, leading me to believe it needs fresh gas and a carb cleaning to free the float etc. Any other suggestions other than replacing the float, planning on doing that while I have the carb off the bike.
SOURCE: 91 yamaha fzr engine turns but wont start
the floats in the carb are stuck. you can try lightly tapping on the carb with a screwdriver that should do the trick.
SOURCE: a lot of gas coming out of the carb. overflow tube, eng on or off
the float pin is stuck or has some dirt in it. try tapping the side of the float bowl(s) with the handle of a screwdriver... not hard enough to break it. if that doesn't work you will likely have to take the carb apart and clean it.
SOURCE: Only stays running on choke, sounds a bit rough, new plugs
Gas these days ****, and standing gas sucks even more. Drain your carbs and flush out your fuel tank. good luck
SOURCE: I bought a 1985 GS 550 LF. It had been sitting
Gas pouring out of the carbs means the float pin are not sealing in thus the over flow.
Go a little down thn .77in , best would be to bench set them.
Take a pipe say from the tank to the feed pipe of the carbs (best would be to remove the tank and place it higher on your work bench to get the gravity flow to the feed pipe of the carbs)
Allow the flow to the carbs and monitor the over flow, see which carbs over flow, remove the float bowl and reset the float and let it go a little less thn .77in, refit the bowl and retry the feed in and recheck..you will come to a point where gas wont over flow, open the bowl and see the level of the gas , it should be covering the jets, but remember that since you will have the float bowl out the gas will show low as when its submersed, the jet stem in the float bowl pushes the gas level up so dont get mixed up when you see the level low , i am sure you will be able to judge it for yourself.
I had the same problem in myYamaha(seca) XJ750R !981and finally managed to win over the problem going over it the way I explained.
Hope this helps! Good luck.
