    Problems with Stihl Ultra Oil

    Yeah, that's what's bugging me too. And since everyone keeps skipping the fact they were running rough BEFORE I adjusted the carbs, that bothers me even more. The 192 would start and then die after you throttled up. Even if the saw stayed idle for 3-5 minutes. The Mantis would start...

    Problems with Stihl Ultra Oil

    Oh I agree with you, I think Ultra is a revolutionary concept, but it needs to be tested more on a variety of gasoline. Example, I know people can't get 93 Octane in California, as readily as you can in Ohio. However I think Firediver125 has hit the nail on the head. Ultra isn't designed for...

    Problems with Stihl Ultra Oil

    I am going to run HP Super from now on. I had to go to another dealer to get it, as my main dealer is only selling Ultra. I am using Shell gasoline with 89 octane. (No ethanol) I took the 192 to the dealer, have not heard back. The 036 I have not torn down yet, I am waiting on the parts to...

    Problems with Stihl Ultra Oil

    Fuel will go bad without stabilizer. Ultra does have a stabilizer in it. Sure I messed up the carb settings, because something was causing the engine to run hotter. I was compensating by adjusting the carbs to run leaner, causing overheating and eventual scoring of the bores. It was already...

    Problems with Stihl Ultra Oil

    No, the majority of my 2-cycle equipment runs at minimum 1 time a month. The Mantis was first, then the 192, and finally last week the 036. Essentially in order of bad to good quality.

    Problems with Stihl Ultra Oil

    I make fresh mixed gas every month (college professor always said that any mixed gas only lasts about a month before it gums) and generally I use a gallon a month. I did mess with all three carbs, as the engines were still running crappy after i did normal routine maintenance. Parts are...

    Problems with Stihl Ultra Oil

    I'm not sure if anyone else is having this issue or not (and I'm guessing people are/should be). In one month, I have had an 036 Pro, 192T, and just cause a Mantis Tiller 50:1 all bite the big one and have scored bores. I noticed the engines were running rough, and would have to adjust the...
