So this fall i've had my carbs crap out on both my old 1980's chainsaw , and my 5 y/o leaf blower. I know well and good its completely due to Ethanol contamination. Ive been doing much research and seems as the expert commercial landscapers and loggers swear by running quality Ethanol free premixed fuels such as VP or TruFuel. Seems to me that running a oil bath 28:1 mix as suggested by the 1/5 scale mfgs is way overkill and limits performance. My new Husqvarna chainsaw suggests 50:1 and im reading that this leaner ratio is 100% reliable. Chainsaw engines take an equal beating if not harder than a 1/5 scale. I think for the sake of my curiosity and the sake of argument im going to try some VP 40:1 premix fuel. I can buy it for $22 / gallon. Im so sick and tired of dicking around trying to keep pump fuel stabilized on all my small engines that don't get run frequently. Even if i blow up my Rovan, its no big deal. Not like its a High end race engine ! Ill be sure and update this thread as i work through a new tune and get some real world experience.
