Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I have a 021 (I think) chainsaw that I couldn't keep running. Got to digging around trying to find out why and found my fuel line had a small crack. Put a new fuel line and filter on it and haven't had any problems for a couple of years now. I use regular fuel and Stihl 2 cycle oil mixed at 50:1

	For Outdoor Power Equipment, I buy Non-ethanol premium gasoline and treat it with Opti-mizer which is a fuel treatment & stabilizer. Even in the old days, it was recommended to buy fresh fuel, keep it clean and use it up in 30 days. I mix small amounts of 2-stroke pre-mix and try to use it up in one season. If storiing for long periods, drain out the tank of chain saws and weed trimmers. It has worked for me. R. Musgrave

	I have been using a product recommended by the local Stihl dealer, it's called Opti 2 two stroke mix, one pack in with one gallon of gas,and use it in everything no matter what the ratio is supposed to be. It also has a built in fuel preservers. I love it,one gas can for everything. Been using it 2 or 3 years now, haven't had any issues.There is a noticable difference in how they start and run,way better. I use Opti 4 in my zero turn with a Kawasaki engine,if I ran that from the day it was new Opti 4 gives you a 7 year warranty on any engine failure.

	I have a MS 250 chainsaw, and a Fs 76 weedeater and these things seem imposible to keep running , I do mix my own gas and oil at 50-1 ratio,, they dont get used everyday but dang when I want to use them I want them to run, they start- sputter around then die - aggrivating- is the ethanol in gas now a factor ? Would it be better to buy the premixed stuff ? Or is there an additive I can mix with the gas to perform good ?
