I'm thinking that pretty

I'm thinking that pretty much debunks the acetone theory. Keep the results coming. Awesome work!

...improvement @ 1oz/10gal

1.8% improvement @ 1oz/10gal ratio of acetone. If the weather is like todays tommorow, I will do a three ounce acetone test. 1 ounce has never done anything measureable for my car.
2oz - 3.5oz might have more of an impact.

*EDIT* Whoops. *thinks to himself* Yeah move the decimal point Will...
The right percentage is 0.18% improvement.


And I think the coleman fuel did something like lubricate the mower engine...obviously it made it run freaky consistant. Lubrication is the only thing I can forsee doing something to smooth out consistancy. So obviously more testing is required.

1.8% improvement? How did you calculate that?

EDIT: I agree, 0.18% looks like the right number.

results

Neato results on the additive mix and definately add a little more acetone - get up on the crest of the curve for more gain . . . 3/10
Some Torco GP-7 testing should be done last as it will lubricate the engine and change further results. If you can't see enough of a difference in the run time then you have to increase the amount of fuel being used say double it to get longer run times with more resolution. You may also see more gains at a lower throttle setting when running acetone than at full throttle.

Mobil gas results [1316.52 seconds average]

Mobil testing:
Now usually I take aproximately 15 minutes between runs to restart. BUT, the wind was freezing today and was cooling the mower very very rapidly. So all these restarts were under ten minutes. I also did seven runs because I could not get close numbers today for some reason. I have kept the funnel covered with foil during all runs but am still scared something got in there due to these numbers being all over the place. So I am going to spray out the fuel line to see if anything comes out...
And I guess if I am off by 1ml of fuel then thats equal to about 6.6 seconds of run time ain't it?

The constants in this round are:
-Seven 200ml runs (warm runs)
-Mobil Gasoline

RAW DATA no conclusion

Typo on run #7? Less than 3

Typo on run #7? Less than 3 minutes? Lets come up with an average. The variation is not that bad. Looks like good results to me.

I didn't expect everything

I didn't expect Coleman fule & Acetone to be so close. I guess there is no significant increase/ decrease.
