Huh, so that's how I address a particular comment, the reply button. So Ken, about the ethanol thing, I want to know some stuff............I should’ve asked this before, but I’m using regular 87 octane to try and get it running. Should I be using something higher? I was hoping to run it on the no-ethanol stuff QT has when it’s actually running so it doesn’t destroy the carb seals or gunk it up as bad if it has to sit at some point, but regular 87 is what I had in a jug when the starter fluid ran out. The 87 is fresh, I filled the jug up for a neighbor a few days before I started messing with the kart.
Firstly, the octane though.......... Never heard a small engine mfr. recommend octane rating higher than 87, and my best understanding of the rating is simply that the higher the rating, the higher the temperature at which the fuel will spontaneously combust. So a high compression engine that makes the air/fuel mixture hotter via more compression might have the mixture detonate before the plug fires if octane rating is too low.
Now the ethanol........... I know nothing about it. Predators have a sticker on the gas tank about ethanol, and I seem to recall it said "No E-85 ethanol", might have that wrong, no matter. I want to know what ethanol vs. gasoline does and doesn't do, what the advantages/disadvantages are, performance/longevity overall, etc. Anybody out there have answers for Ken and for myself?
Bonus: Any info on kart racer's methanol would be of interest, and any would be more info than I presently have.
