Is there an auto choke of some sort? If so, this might be my problem.
I can pump the prime bulb and the mower starts right up. Then stalls.
After I do that a "bunch" of times it will keep running.

Since I don't have a choke lever I'm GUESSING there is an autochoke which might be my problem.

HELP !!!

thanks

Any ideas what could cause this kind of behaviour?

Hi and welcome the forum

Can't really answer the auto choke part, but if it had a auto choke, it would not probably have a primer. Both a choke and a primer do the same thing, get more raw gas into the cylinder.

I have a 6HP Lawn Boy push mower, that only has a primer.

Now I also have snow blowers that use both a primer and a manual choke. Of course the are for cold weather, which makes harder to and keep running

Here is the JD site, try and look it up for parts:

thanks, I'll have to get the exact part number of the engine and try a search there.

In the meantime, any theories what could be causing the behavior I'm witnessing?

Probably running a little to lean of mixture, could just dirty or gummed up a little.

Yup, sounds like a blockage of some kind in the carburetor. It isn't able to suck it's own gas, but will run from the gas that's pushed through from the primer.
