Ok so I have been using a 30cc Redmax 2 stroke and I can take the guard off and run that thing wide open with a ton of line. Well of course it still has the typical redmax problems so I wanted to buy a stihl but all three of the stihl dealers here have a diffrent opinion on what stihl will do the job. Please anyone tell me other than redmax wich can be run this way and it doesnt have to be just stihl I just like the product.
