LP forklift Won't stay running --

I'm trying to help out a friend diagnose an issue with his TCM FCG15-N6 LP forklift that starts, but won't stay running unless he presses and holds in the little spring-loaded button on what I'm guessing is a fuel diaphragm. (Located on left-front of engine bay)

I have a basic knowledge in automotive and small engine repair, but when it comes to LP Forklifts I need all the help I can get.

I'm not seeing a way to share pictures, but I've put the picture of the diaphragm and the spring loaded button in my profile signature.

Thanks!

Thanks for the quick response.

I'll relay that information to my friend and hopefully with a little digging we can spot the problem.

Once we do this I'll certainly respond back with the findings.

Thanks again for the information!

The button is actually a primer for the vaporizer if you have to hold it in that tells me you aren't getting fuel through the vaporizer
Possible causes would be faulty vaporizer, faulty mixer ( not pulling enough vacuum to close diaphragm in vaporizer) as engine turns over vacuum pulls on diaphragm to let fuel in
You can turn off fuel remove front of vaporizer and check diaphragm for a tear or hole
