Will Octane booster hurt stock mopeds?

I have some, it says it cleans gunk out of your carb & Fuel systems, while boosting your octane, but it also says Treats 10 Gallons. Would a Teaspoon after you fill up hurt at all?

No, It shouldn't, but there's really no need for your octane to be boosted. High octane levels are for high-compression high-performance engines. A higher octane level makes the gas harder to burn to avoid premature combustion in a high compression engine. But if it cleans fuel systems also, I suppose you could put in a little bit, it won't hurt the engine, just might (emphasis on MIGHT, I don't really know if it would hurt performance) make it run a little slower while it's in. If the bottle treats 10 gallons, then put in 1/10th of the bottle for every gallon of gas. I'm sure you already figured that out, though.

Hi! You really don't need octane booster in a stock engine.You could use the carb. cleaner though.Like you said,don't use much:usually if it's just carb cleaner it'll treat 14-21 gals.of gas,so don't use over a tablespoon,which is approx. half an ounce per gallon.Then you'll need to nearly run that tank out before you add it again.I'd put the octane booster in a car or truck and just use reg. carb cleaner in the moped,unless you really want to see if it helps you.If you use a quality gas that has no ethanol or methanol added,it already has cleaning additives in it.But BEWARE cheap no-name gas,because it has usually got alcohol(ethanol or methanol) and usually does little to keep your tank,lines,carb.,and combustion chamber along with the spark plug, from gumming up.Why,MARATHON brand gas actually has everything you need plus fuel stabilizer so it won't go bad over a few months storage.I know this because I used to drive a tanker truck for them and read all their bulletins.The only other gas that I know doesn't use alcohol is SHELL brand. If you use this good quality gas ,you won't have to add carb. cleaner only about every other tank.No matter what you've heard from environmentalists favoring the use of Alcohol in your gas,remember it is a destructive force on small engines.STIHL CHAIN SAWS will void your warranty if they see you've put any gas with alcohol in their saws.That should tell us something! BYE!

Re: Possibly

Fuel additives designed for 4 stroke engines can cause problems with a two-stroke. Remember also that the fuel mixture is by volume, so any additive you put in your tank reduces your fuel ratio, i.e.: makes it leaner.

I usually add about a half ounce of Wynn's liquid carb cleaner to every gallon of gas. I think that the engine cleaning part of the additive you describe is good, but you <b>don't</b> need your octane boosted.

Re: Will Octane booster hurt stock mopeds?

Thanks for the info, well I used it to try to clean my fuel systems out, because when I fully hit the throttle it dies out, but if I hit it 1/5 of the way it goes a little. So I Figured I had gunk in my carb or somthing, so since the booster crap didnt work as well as I expected. I took it all apart , took all the screws sprayed carb cleaner in, blew it out with air pressure, put it all back together,(as Fred does) but yet it does the same thing. I am close to taking it to a more advanced mechanic than myself., but I hate doing that, for 2 reasons: it cost money, & its easier to have all you moped gurus help me out, Thanks.

Your engine dies out when you give it a fistfull of throttle?

It <i>does</i> sound like a carburetion problem (maybe the main jet or the needle jet)? I had a PA-50II that wouldn't idle until I found out there was another jet underneath the main jet in the float bowl --it had all kinds of little pin-sized holes in it. Since I've cleaned them out, it idles really slow like a Harley.

Try taking your carb apart and soaking it overnight in carb cleaner. <b>Remove all the rubber/plastic parts first</b>. I've screwed up gaskets that way.

Look carefully <i>everywhere</i> for extremely tiny ports. My Vespa Ciao was running crappily until I discovered there was an extremely tiny port just below the jet.

When you have your cleaned carburetor put back together, turn it upside down and then right-side up again and make sure you can hear the float moving around inside --if it doesn't move very easily that might be a source of your problem.

Good luck!

Chris.

Re: Will Octane booster hurt stock mopeds?

is your air box on? if it is then do what cris says or if that doesnt work try a bigger main jet

Re: Will Octane booster hurt stock mopeds?

My float is moving good, & My air box is on. So I will try soaking it overnight, I havn't done that yet. Thanks
