Honda GC190 Carb not taking fuel

[illMATTic]

Hi guys. I have a GC190 with a stock carb. I am trying to get fuel to it but when the line is hooked up to the carb, I get no flow. I have it mounted under an in-frame tank with a filter and shutoff.

Everything flows well if I pull the line off the carb. Any ideas as to what the problem is?

Thanks

The float valve in the carb is stuck.

Ahh haaaa. I should take the bowl off and make sure its moving freely?

Yaaas Dahlink. This engine didn't come off a pressure washer did it?

 

[illMATTic]

Yes it did.
I saw that many guys on here were doing it. I have had it running but it always runs out of fuel.

I do not have the stock fuel pump hooked up. I figured the fuel would supply itself from gravity.

It should gravity feed with no problem, but I have been surprised before. Mine came off a pressure washer, and I found the carb was full of chalky white stuff. Seems it had ingested water at some point before I got it. Just for kicks, hook the tank into the pump and see what happens.

Thanks. I'll pull it apart tonight and see what happens.

The bowl is full or near full. Should my filter fill up with fuel when I turn the fuel on?

How did everyone else run their fuel?

Generally, the filter gets full as the filter gets more plugged. So it's not running with the bowl full?

yea I found the same thing to my 8hose briggs off of an wood chipper just full to the brim of white powder

The engine will run. However, it will not draw any fuel through the line. The line is free and flows well when I remove it from the carb. When I put the line back on the carb, the engine will run fine but use all the fuel out of the lower part of the line and filter. It will do this with or without the tank cap on. :shrug:

I wonder if I need more fuel in the tank? Give it more pressure?

 

[Neck]

But you say the fuel bowl stays full?

 

[illMATTic]

The bowl stays full while ther is fuel in the lower line. Then most of the bowl is used up then it stalls.

When I loosen the screw on the bowl drain I can pass fuel right through it. So the flow is there.

Can you take a picture of the bike and the fuel tank and how its feeding the carb for us?

 

[Neck]

Maybe your bowl vent is blocked and its air locking

Ill get a photo this evening.

always check the rubber in the shut off, it has moved and the little hole probably isnt lined up to let fuel flow. open it up and you will see what I mean.

 

[illMATTic]

Here is how I have it run. You can see the fuel only fills a small part of the filter. Then the lower part of the line under the filter goes dry after it runs for a while.

I have not checked the shut off valve yet. It was too damn hot here yesterday.

I cant tell from the pic, is the bottom line full? The filter looks normal.

 

[illMATTic]

ya the bottom line has fuel.
