This is a 7FGCU30 with a little over 30,000 hrs. When it is warmed up it starts and idles fine. When it is cold there is only one way to start it. I disconnect the LP line from the tank, evacuate the fuel from the system, and reconnect the line to the tank. Then I spray some carb cleaner in the mixer. Then, with my foot on the accelerator pedal, I spin it over and it will start. Before it dies I will open the valve on the LP tank. It will remain running as long as I keep my foot on the pedal. Once it has warmed up I can take my foot off the pedal and it will idle on its own. If I take my foot off too soon it will die and I have to repeat this process. Any ideas if this is in the mixer or in the regulator. TIA

I replaced the regulator. Problem solved. Thanks for the help.
If this unit has an Aisin regulator you can drain the byproduct from the regulator. With the unit warmed up well. You can find a 12mm plug on the back lower side of the regulator. Shut down the unit remove the plug. You may need to put a tag under the opening to catch the byproduct. Allow it to drain. Repeat till you get little to nothing coming out. This will help. This should be done on your PM services. It will help prolong your regulator life.

That's a common symptom of a bad regulator. The pressure is getting too high and flooding the motor. Once the crud in the regulator gets warmed up, it helps.
