As the Engine Turns!
With the proper oil/gas mixture, your engine should hum nicely. But what does it sound like (or act like) when there is too much oil in the mixture or too little?

Re: As the Engine Turns!
With too much oil you'll probably have some smoke coming out of the exhaust and it just won't run "right." More oil = less fuel per intake quantity = motor running lean.
Not enough oil...it'll be running richer, and if you really don't have enough oil, something is going to break eventually.

Re: As the Engine Turns!
i can't get the mixture just right...i think i got too much oil in the gas
no real power like before and top speed is reduced...and yes, i see smoke in exhaust as well as traces of oil near exhaust port...
i mixed 4 oz of Golden Specter with 1 gallon of gas (i hope it was 1 gallon)

Re: As the Engine Turns!
That's 32:1 gas : oil, that's not bad. I run 32:1. What notch is the E clip on the carb needle?

Re: As the Engine Turns!
32:1 is O.K. and definitely not too rich on the oil....
I would have a look at the plug and see how it reads. If you are using a good 2 stroke oil, especially a synthetic, you should see no smoke, except maybe a little on start up.
Something else is amiss.

Re: As the Engine Turns!
like i said earlier, it is Golden Specter 2 stroke oil and is suppose to be really good. 32:1 ratio and I do see smoke (at full throttle)

Re: As the Engine Turns!
I run full synthetic, my engine will smoke a little at start up and a little when I stop at a light for a second or two.
I would pull your plug and take a good look at it...this will give you an ideal of your air/fuel mixture.

Re: As the Engine Turns!
How much smoke are we talking about at full throttle?

Re: As the Engine Turns!
I run Valvoline at 32:1 and I only get smoke when I start it up with a bit too much choke. After that, there is no smoke whatsoever.
What does the plug look like? If it's black it sounds like you're still running really rich. You may have to solder and redrill your jet or get a new one, since you're on the top notch already...
