Are there other things that could cause fuel to be dumped into the carbs? Just had the carbs cleaned and float adjusted at the shop, and barely a day later fuel is pouring out of the carb relief hose. 1997 honda shadow vt600

Re: honda shadow vt600 dumping fuel into the carbs
Hello ddsaul2...If it's only been a day since the shop adjusted the carbs. you need to return it to them and make them do it right. Sounds like a float valve is stuck and not closeing.They may have cracked a seat... There could be a pin hole in one of the floats causeing it to fill up with gas and sink. You can check and make sure all the vacuum lines are connected and possibly GENTLY tap on the carb fuel bowls to see if the float might be stuck alll the way down. Personally...if i paid for a carb tune i'd make them fix it. Surely they gurantee their work. Good luck...i hope this helps

Check the fuel level in the float chambers of the carbs, it could be too low! Readjust the float to obtain correct level. Blow out the primary and main jets with compressed air.
Hope you adjusted the air screw mixture at the right temperature of the engine i.e. you need to warm it up and than adjust also check the valve clearance of the engine.
Hope this helps
sounds like the float and needle are allowing fuel to continually leak into engine causing it to flood out. That's why you have to drain the fuel from carb BEFORE you can attempt to start it. that way there is no ADDITIONAL fuel entering the engine while you try to start it. and once it starts, the engine is then "cleaned out" and you can add fuel again.
The "fix" is to adjust the needle and float or rebuild/replace the carb.
Dump out old gas. Fill with fresh gas. Always use Stabile in gas. Clean or replace park plug and air filter. Check oil level. All mowers have a low oil start cutoff. 30w oil. If any grey in oil moisture contaminated, dump out old oil and refill. Check fuel line for cracks or leaking. Check primer bulb for cracks, replace if required. Clean outside of carb with carb cleaner to ensure easy choke operation. Remove carb bowl from carb, ensure float hangs down freely. float down fuel flow, float up fuel flow stops. Check bowl screw for hole thru bolt, if so clean out hole.
Change all fluids. Throw out the old gas, it will be substandard (unless you have a beater car to mix it in). Check the tank for rust. If there is a lot of rust or you locate rust in the carburetor, fix it with an acid solution. Drain the carbs and check for what comes out. You should get at least 100 ml of yellowish fuel/varnish. If that doesn't happen and you don't think the carbs were previously drained (drain screws left open and/or fuel tap set to "off") then the carbs are likely gunked and will need to be removed and cleaned.
A plugged Idle Jet will give you an erratic idle (up,down,up,down) and also draw in liquid fuel instead of vapor. The 'O' Ring between the float valve seat and carburetor body and the Float Valve are the only two places the fuel may enter the fuel bowl. If the 'O' Ring or Float Vale is leaking the float cannot regulate the fuel level. To test a fuel pump you will need to test for Pressure and Volume.
