octane

I have been building a twin engine go kart over the winter and it is nearing completition. It is powered by two Tecumseh HS50's. I built the hs50s with billet rods, new rings, seals, etc... I milled the head down a little to bump up the compression, fabricated a intake for the mikuni and opened...

At what temps does your little mini call it quits? All the way to 7 degrees i took my CT200U with its china motor. I was very impressed with the little critter, in warm weather it starts with 3 pulls, at 7 degrees (cold as it got here) it took 7. Once it cranked it didn't quit though...

Went by a local gas station the other day and seen that this gas station is selling 110 octane racing fuel at the pump for $8.50 a gallon. Never seen that before at any any gas station but probably never looked that hard cause too busy buying the cheap 87 non-ethanol octane. Does or has anyone...

What are the benefits ,or are there any ? running a stock predator motor on a high octane or putting in a little octane booster . :doah:

I've searched but can't find any answers. I'm running a predator 212cc with a mod 2 cheater cam 18lb springs and I milled the head down .050 and running 140 emulsion and .039 jet bored out carb and air intake and straight exhust. What fuel do you think would be best???

If I buy 91 octane instead of 87 would I see a benefit or would it be a waste of money? I understand some Briggs engines can self adjust to meet an octane rating but I don't know if mine can ~ here are the numbers. MODEL = 135502 TYPE = 014501 CODE = 93050707 Thanks a bunch guys.

is any one running 91 octane in their briggs? if so what steps did u do to make it work? i tried it and it ended up fouling my plug but i did notice a huge difference in performance.

Hey everybody, this is a friend and customer of mine, go to the link and vote for him. He is the owner of Delta Cam, big Mitsubishi and Subaru cam maker.... Vote for him guys..... OctaneAcademy.com

does anyone know if i can add something to it i.e. oils or something so i can run it in my tec (100hm) flattie? maybe some of the old hands know something that works- to be able to use AV 100LL aviation fuel and a mix ratio with something else to get it down to a useable 87 octane? :wink: anybody?

the paperwork that came with my clone said to run 91+ octane but would it be ok to run 87 if i'm not going to beat the piss out of it? i've owned several older mini's inwhich were used and didn't come with instructions and i ran 87oct with out any problems i even have owned a few lawn mowers...

Hey I am wondering has anyone seen any difference in running 87 then ran 93 octane. I am wondering is there in different in power? Would i get more power or it about the same just more money on fuel.. In 2 strokes if your motor is stock and you put 93 in there it basically a waste but not sure...

I have a honda gx200 with a billet rod, flat top piston, 285 cam, head ported and milled.080 with 28.5mm intake and 25mm exhaust valves, cromoly push rods and billet 1.2 rockers, arc aluminum flywheel, 28mm mikuni, I am currently running 94 octane and I want to no if I can run true blue (110...

If I change my gx200 clone to a billet rod, and a flat top piston and remove the gov? What octane rating if I also install a 14cc cylinder head? One more question, when I pull the gov I'd like to adjust the timing, how many degrees should it be advanced?

Looking to bump the cr soon maybe somewhere north of 12:1. From read throughs of dated threads seems that between 11:1 and 13:1 is the grey area where engines begin their transition from regular gas to the higher octane. When transitioning to these higher octanes do the preventive checks...
