Jiffy stealth stx problem. Please help

[tafts ta]

I have a three year old Stealth Stx that sat garaged, no gas in tank for two seasons while I ran a nils power auger. Just fired up the jiffy with brand new 50-1 gas. Took a few minutes, but got it going. But u can't get it to idle, can't get it to run choke open, and get get any good power.

Checked and no air leak, good spark, all hoses are soft and not brittle. Air cleaner is clean, muffler clear, and carb looks spotless.

I held it and ran it for about ten minutes at half choke with the fuel wide open hoping to maybe burn something loose.  Same problem.  Any suggestions would be ideal

Sounds like a fuel issue, perhaps corrosion in carb passages is restricting proper flow. I'd try soaking and/or cleaning out with carb/combustion chamber cleaner or Seafoam, etc.

This doesn't necessarily address your problem, but you could try a 40:1 fuel mixture as per Jiffy recommendations:

Hope this helps!

Thank you.  I always run my gas (augers, outboards, tractors, whatever) with Startrol in it, so hopefully thats not the problem. I did not see any signs of corosion in the carb when I looked, but those damn things are so tiny.

I always run 50-1 because I also add a shot of the startrol to it, I figure that has to add a little to the mixture., but I'll take it out and try 40-1

it could also be a bad diaphram in the carb

Put a couple capfuls of SeaFoam in the tank and run it like ya stole it for a few minutes. Let it sit for a while and repeat it several times. I did this with a 2 stroke tiller with a 2 hp Tecumseh on it and it came right out of it. I would think it would be worth a try.

Did you have the fuel tank full when you put the SeaFoam in the tank? My jiffy stealth stx is doing the same thing. It ran really good when we first bought it but now it has the same symptoms as stated above.

The tank was full so I put it in and shook the heck out of it to mix it.
