You say the carburetor is new?
Many carbs on small engines today have a valve under the float bowl if it is that type of carb with the fuel bowl at the bottom of the carb.
There is a fuel shot off solenoid with a wire attached to it right under the fuel bowl.
I have seen those go bad.

They need voltage to the solenoid to pull in the plunger that is inside the fuel bowl.
Many times that plunger is corroded or stuck and if it is stuck it shuts off all fuel flow to the main jet.

I feel your getting fuel to the carb and possibly into the carb but if the main jet is plugged you will not get the fuel to flow into the engine.
Now if you loosen the fuel bowl and fuel comes out you know the jet is restricted.

Those electronic plungers or solenoids can be taken out and the plunger part snipped off or ground off so you will no longer have it plugging the passage.

Those stupid solenoids are as handy as GFI receptacles.


Winner, winner!

Yes, the carb is new. The old one did the same so I hoped it was bad and the new carb would fix the issue. It is my first time working on one with the electronic solenoid. So far I'm not a fan. :)

I cut the tip off many of those solenoids and stuck them back in and instant startup and run.
I am not a fan either.
There really is not much to those small carbs.
If you do not have any fuel in the new carb you could have a stuck needle..Sometimes after a rebuild the needle will sit in the seat and get stuck this will happen if the rebuilt carb sits for a long time on the shelf with needle in the seat waiting to be sold.
When I build a carb I put a tiny bit of Quicksilver marine 2 stroke oil on the needle.
It does not dry up and get sticky and will not harm rubber.

I also use it to lube valve stems when I build cylinder heads.


Friend has a couple nice riding mowers that quit on him just 2 weeks ago.
One does not have a deck under it and he uses it for pulling stuff around his acreage.

He said i could have the one with the mower deck if I needed it.
I did not need it. But I felt compelled to fix it for him.
It was a failed fuel shut off solenoid and gooey crud in the bottom of the carburetor.

Runs great now. and took less than 30 minutes to have it running.
He was happy.
Steering was very stiff on it..I lubed up the pivot joints and it got much smoother.
He said his wife hated it because it was hard to steer. Not hard to steer now.

Assuming he is spraying starter fluid into the carburetor, if the carb is stopped up he wouldn't be able to get it to run on starter fluid, right?

Pull the fuel float bowl and see if the float is stuck

No, a carbs can be completely gummed up and as long as you do not block the air intake it will run on starter fluid.

Swampratt for the win. In my defense I plugged the carb wire in the old plug thinking it still had power. A mouse must have got to it because it had no power. I put it directly on positive side of battery and it works. Now I get to do a little rewiring. I will win this battle. :)
