do I have a carb issue, or something else?

[DeliBoy 3]

I was wondering if I could get some help with a fuel issue. My Wheel Horse is dumping fuel after the carburetor, and I'd love some help with determining what to do next.

 

This is a Onan E140V on a Toro 244-5. I'm trying to resurrect it after about 10 years in storage. Although the fuel tank was empty, I don't remember if it sat that way for any time.

 

After installing a new battery & spark plug, and an oil change, etc, I filled up the fuel tank. After about 30 seconds, I noticed that fuel was dumping out, and the leak seemed to be between between the carb and the head assembly.  There are two gaskets and a insulator that are contenders as well. There are two bolts holding everything together and I've checked that those are tight.

 

I am already overbudget on this project, and would hate to spend $300 on a new carb (part number NN10668 (corrected, I first had the wrong part #)) if I don't need one.

 

I've been reading through the forum but don't see any similar issues. What would you do in this situation? Should I use a carb cleaner? Replace the gaskets? Rebuild the carburetor (or have someone else do it?)

 

I really appreciate any help.

First guess I'd say the float is stuck.

yeah , take the carb apart and clean it , making sure the needle/seat are not sticking. check float height too. be careful not to wreck the gaskets and/or put in a carb kit .

 

not familiar with that carb, it leaking that bad it may be coming from some sort of vent on top

I would also float stuck open. remove and clean

 Thank you all. Guess I need to learn about carburetors now.

Since this engine has been siting so long I would suggest you replace the fuel hose and filter because they probably have some drier gunk in then that will cause you problems in the future. Remove the carburetor, disassemble it and soak it in Carburetor Cleaner for a couple days then install a rebuild kit.

Good idea, I will do that. Thanks again.

Also, at this point it's possible that you've diluted the fresh oil with gazzoleen by it dumping into the cylinder so it might be a good idea to dump that oil and add fresh again after you get the carb straightened out.

 

You MIGHT get by with just removing the float bowl and refreshing the float needle.  OR, the float might not float any longer.  Might be gazz inside it.

 

Sometimes a sharp 'rap' with a screwdriver handle is all it takes to unstick-a-stuck.

I agree with others, a simple cleaning may fix the issue. There area bunch of videos on YouTube showing how to do that.

 

Ultimately, you can get a new carb on fleaBay for $95, not $300

Removing the tank and cleaning the it and possible a strainer that might be in the bottom of it could also be needed. Sitting 10 years anything in it turned to tar like goo or rocks.

While it's apart make sure the float actually floats. I've seen them crack at the seam and they look okay visually but are still faultym

Just a followup. I was able to get the engine up and running again. I took the carb off and, without disassembling it, sprayed in a lot of carb cleaner over a week. After reassembly, there was no more leaking fuel.

 

I think part of my original problem was I was working while it was about 20 degrees outside. Today it was 50, and after some final work on the electrical system and fuel lines, it fired right up after ten years in storage. I really appreciate all the advice I got here. Thanks again.

 

Now I just have to figure out if I should bother attaching the snow thrower this late in winter!

You might get another month of use in the mitten!
