I have a Scotts swivel wheel mower with a Tecumseh engine that will start and run for about 5 seconds and stop ,, I can cover the top of the carb with my hand after it starts and keep it running for a little while .
I put a carb kit in it and I have checked and rechecked the needle & seat but it does the same thing.
Any ideas would be appreciated, Thanks, RickM :confused2::confused2::confused2:

Are you getting a good fuel flow to the carburetor? Clogged fuel filter , gas tank, fuel line, etc. ?

Make sure the main carb jet is clean. could be in the bowl nut or in the base of the plastic bowl assy if you have that type of carb.

I have checked all of these and they are as should be.

Carb was cleaned in carb cleaner to remove all varnish and I installed new kit parts and gaskets.
What do you mean about the bowl nut, how could it cause a problem?
