I have a Deere Push Lawn Mower Model JS60H. It has a Briggs Vertical Shaft Intek Engine 6.5 HP. The Model Number on the Engine is 121601-0269-E1. The Code indicates it was manufactured in 2012.
Problem - this mower will not prime and start. When starter fluid is sprayed into the carburetor intake or the combustion chamber after removing plug it starts and runs fine.
After using the Primer Bulb a pull of the spark plug reveals it is dry.
So far - I have carefully checked the gas tank for leaks.
I replaced the fuel line and inserted a new in line filter. Th The filter was certified for this mower. The large end of the filter is toward the fuel tank. Upon removing the fuel line at the carburetor there is free flow of gas.
I replaced the carburetor with a new one. When I took it off the Engine me to ultrasonically clean the engine the bowl was full of gas as it should be! After cleaning in US I used pipe cleaners, wire, gum out carb cleaner and compressed air on all holes.
After trying multiple air base gaskets, I installed a NEW air cleaner base and gaskets.
I am at my wits end!!!! Despite all of this the lawnmower won’t prime and start!!!
The question is WHY????
Any help you could give me would be greatly appreciate.
The port from the primer to the carb is clean and open.
Today I am going to make sure the hole and passage to the main carb jet is open.
Lastly, there was a fiber gasket missing free m the carb to intake maniface and one retaking bolt on the EGR had fallen out. The EGR was cleaned and the exit tube into airbase was confirmed to be open.
I will repost if any of the new findings/fixes made any difference.
Is this a engineering flaw in the primer carb system???
It is literally driving me crazy!!!!
