I've never heard of it. You should be using a mid-grade (89 or 91 octane) name brand gas like Shell, Exxon, BP or some quality brand of gas. That gas you're using is of unknown origin and quality. All gasolines are not the same and I don't care who tells you otherwise.

I have some very old Stihl equipment and it all runs like a top, day after day. I use Shell 89 octane. If you look in your Stihl owners manual it will tell you the minimum octane is 89.

Yup, you're saving money by using cheap low octane fuel, but hey at least they run good when it's not too hot.
That or the ignition coil, only other possibility.

Try switching to Phillips 66 as they have no Ethanol in the mix now.

I have to agree, try running a better know name brand gas. Question, are you running the with guards on or removed. I've been guilty of running with guards off and longer string, the engine doesn't turn the rpm does not get the cooling effect of running more rpms. Just throwing another idea out there.

+1

When the trimmers get hot and dont want to run, pull the plug out, ground it to the top of the cylinder, pull the engine over and look for a spark. Watch out because everything is going to be hot as hell. lol at whoever thinks its the gasoline or mix. . . It wouldnt run long enough to get hot and shut down if that were the case. plus his other equip is burning the same fuel . . . . . .

It is easier and faster to just carry a extra plug, and lay it on the cylinder , hook the coil lead to that.

It could very well be fuel, especially ethanol, you don't think already hot fuel next to a hot engine is not going to get hotter?

You're telling me you've never heard of QuikTrip?!?!?!?!?!?!? They are the biggest gas station chain in the Midwest. They put all the other gas stations out of business. They are the best. They have quality gasoline, no doubt about that. Huge lawn care companies like Embassy (operates in 4 states) and Epic (HUGE company) fuel up at QuikTrip. When I get gas every morning around 7:30 it's ridiculous how many lawn crews are there. 10-12 at a time all getting ready for the day. Around noon you'll see a ton of crews at QuikTrip for lunch. Anyway, I could use 91 instead of 87 if you think that will help. But, what I was trying to say is that I,ve used QuikTrip fuel since day 1, no problems with the weed eaters until these past couple months.

QuikTrip



It's really our only option in KC, but they are awesome

Nope, never heard of QuikTrip. That's be like me asking you if you had ever heard of Trade Wilco or Dash In. They just regional retailers of gasoline. Who makes their gas? More than likely it's just spot market gas. Anyway. Try their mid grade gas for a little while and see if it helps. It'll cost you what? 50 cents on a 5 gallon can?

I'm not trying to give you a hard time. Just trying to help you fix your problem.
