I have the same gen. Same problem as your's. I changed plug, regulator changed the secondary regulatir. Didnt help. I think the problem is with the automatic choke. Watch it sweep back and fourth during startup. It backfires when the choke is fully closed.
I just had a similar issue with my Pulsar 12000w dual fuel generator. It was the valves needed to be adjusted. They were not far off just a thousandth of an inch, but it was hard to start and backfiring even more than yours.
You should be smelling some propane when you're attempting to start and it isn't... unburned propane should be exiting the exhaust. Also, check for clogs or debris in the connections, lines, and air intake.
It remains open. It doesn't run on straight propane, it still needs an air/fuel mixture for combustion. I have the exact same generator, never use the choke. As a matter of fact, the manual states not using the choke when running propane.
Choke stays OPEN during running generator. Go back to basics: Fuel, spark, compression, timing. Check valve adjustment. Remove propane hose from gen and check for good flow with both tank valves fully open. I use a dual tank setup and it runs flawless.
@@christianlords1340 It is a bad idea since the valve is on the side. What it does, and why large propane tanks are horizontal, is that it increases the surface area of the liquid propane so that it more readily boils, increasing pressure. Since your valve is on the top, this wouldn't help at all (unless the tank is empty enough to have the LP below the valve).

How long does it last with an 100lbs of propane
So whats the need for two tanks?

Have you tried changing the spark plug? Ngk bpr6es gapped to maybe .015 - .020?
Too much combined pressure intake? My understanding the choke is only for gasoline mode perhaps this is for specific make / model

You need to put the generator under full load to see it will still run right
It's been 10 months since you put video, have you resolved the issue? I have 2 simple solutions to fix your issues.
1ST‼️☝️
Fuel selector
I bypassed the fuel selection valve now, and replaced the spark plug and the unit works fine now. you can check out my later videos showing this.
Just saw this comment, it seems a ton of the machines have had this faulty part, glad you fixed this issue!@@christianlords1340
When running in propane mode, the choke needs to remain closed. This is different versus gasoline mode.
I was wondering about that, thanks. makes sense now that i think about it.

I have the same generator now for three years and it will run no problems off of a 20 pound cylinder. Has never had gas in it.
When you turn the tank valve open you are supposed to turn it all the way open.
If you don't open the valve slowly, the sudden pressure distorts the diaphram and it will only run with full choke
odd...hmmmm?
Nossle down
Try turning your tank sideways n elevated.
why would you say that?
