Hey Russ,
You know that my pw can balance a quarter on it's side. You helped me get it there with the right gear.

What I can't figure out is why it stops running at 1/2 tank full of fuel. About 2 hours run time.
Runs perfect, no problems other than that. Top it off and it's fine for 2 more hours.

I usually can get almost 4 hrs out of a tank of fuel.

Any clues?? It has been pm'd to the hilt. Just thyis one issue.

The tank is on a briggs vtwin on top.

Same thing happend to me and went back to a old gas cap and fix it. This was on a new honda 13. But I have gotten that info off PWI. Thanks
I was thinking that the cap is not vented enough for the gas to flow to the carb.

Had the same problem with my back up 13 hp Honda...eventually went back to the older style gas cap and all is well again.

Here are a couple pics. The big cap is the one the machine came with. The small one is the one I relplaced it with. The repair guy here told me Honda actually had a recall on these big caps.

That's helpful to know I have the better caps. My gx390 had been shutting off and I think my problem might be that when its not perfectly level the oil flows away from the low oil shutoff sensor. I add a little engine oil or level the machine and it works.
