Carb leaking fuel

So I pulled the rebel out cause it hasnt been started in a while. Turn the gas on put my helmet on go back to the bike and i can smell gas.

I looked and real quick spot gas dripping off the left rear bowl screw every second or two. Checked as best I could the screws were tight figuring m as its leaking cause it's at an angle. But still leaked. Checked the overflow hose, dry.

Rode the bike to lowes and left the gas on when I went in, came out the bike fired right up so I know it's not flooding the engine. A few hours after when things were dried up I turned the gas on again, first place I saw wet was around the barbed fuel inlet then around the whole gasket.


So any hints where to start looking? I'm thinking fuel line first (in southern California if that means anything for the gas used) I highly doubt the brass barb is leaking since its pressed in, after the fuel line i have no clue

Thanks

Michael

If it's not the fuel line, I'd suspect the bowl gasket. Putting your bike info in your signature can be helpful when trying to diagnose issues for you. See my signature for how to do that.

If you pull the carb, you may want to replace the screws with socket head type. Never have to worry about being able to get them off without buggering them up.

Keepin' all the left over parts. Gonna use 'em to build another bike!

I'll try to ad the signature stuff right now.

The bike is a 06 rebel 250 I was thinking bowl gasket except shouldbt the fuel level be lower than the top of the bowl even in the side stand? And the over flow tube was dry. I guess when I get off my ass I'll fiddle with the. Fuel line then pull the carb off and check the gasket. Any pointers on knowing a good gasket? Just not hard or cut?

Thank you

Michael

If it isn't overly stiff or cut, it may be good. But they loose resilience over time and may not seal properly, which could be causing the leak you see. The part number for the gasket is 16163-HM3-A61 if you want to order it from your local Honda dealer This might be cheaper, depending on what your dealer charges for the part. https://www.ebay.com/itm/Honda-OEM-P...dbaf7b3cee16b4

So I cant figure it out. All the gaskets look brand new I dont remember replacing them I just remember cleaning the carb. I'm still wondering tho how I could have flow out of the gasket and nothing out of the overflow tube, even when the bike of vertical the fuel is dripping from the screw but not out of the over flow.


But I'm going to buy a gasket kit for it rebuild the carb then see what happens at this point I'm hoping it's just something I didnt see

The overflow tube is higher than the bowl and intake. If the bowl gasket is leaking, and the float valve isn't stuck, gas probably isn't going to get high enough to come out the overflow

Thank you for your help flitecontrol, so I rode the bike it still leaked, pulled the carb didnt see anything wrong so I ordered a carb kit and put the bike back together while waiting for the kit so I dont lose anything. Well yesterday I was going to ride the trail90 but broke the brake light putting it away so I pulled the rebel out. No leak!?!? So I'm going to assume the needle was leaking? Probably junk from the tank since there is no fuel filter. I'll still rebuild the carb when the kit gets here.

Thank you for the reply and help flitecontrol

An inline fuel filter will help keep any contaminants in the tank from reaching the carb. I'd recommend installing one before putting the rebuilt carb back in. Riding can unstick a float valve, and that may have been your problem. If you have the problem again, try tapping on the carb bowl with a screwdriver handle. That can also unstick a stuck float valve (sometimes).

BTW, so we are clear on terminology, "needle" refers to the upper piece in part #2 in the diagram below. The float valve is #22. https://www.cheapcycleparts.com/oemp...31c/carburetor
