Hello, my name is ***** ***** I am going to assist you with this.

What is the serial number of the genset?

Technician: Hank F., Technician replied 2 years ago

Ok, you didn't specify how cold "cold" was. LP is not the most efficient of fuels, and is a very temperature dependent fuel.

The colder it is, the less reliable LP is.

Another factor is using too small of a tank, and/or the tank being too empty.

Assuming the temps you are describing are not below about 20 degrees, you have a minimum of a 250 gallon tank, and it is at least 1/4 full, then the problem is likely in the genset itself.

Are the block and battery warmers actually working?

When was the last time this unit had a good tune up?

Is the choke working properly? To check, remove the air filter cover, and set the switch to MANUAL. The choke should close for 2 seconds, open for 2 seconds, close for 2 seconds and so on, until the engine starts.
