HooKay ,
Remembered I used the acetone as was the lower half of the methanol , and the damp season .
It was said to absorb any moisture from the methanol . ( which can be absorbed from atmosphere )
And also somewhere it said acetone was a ' ignitor ' when used in fuels .
Just dragged this outta R C groups Via googlesearch on acetone / glow fuel . Which reminded me why I cautiouslt tried a drop .
" Adding 3% acetone for 2 strokes can help with starting and idle (although I've never had a problem with straight methanol). A fellow club member who does a lot of experimenting with 4 strokes found that 5% acetone gave much easier starts and eliminated kicking back, no more thrown props. Acetone is added to Shell A Racing fuel (3%) but in that case I believe it's done because acetone reduces the hygroscopic ability of methanol. As a fuel, acetone is only about .6 as good as methanol but in the very small percentages needed the advantages outweigh this. "
" Acetone isn't used as a power booster the way nitro is used. In 2 strokes it's recommended to only use about 3% as an aid to faster starting and somewhat lower idle speed compared to a zero nitro fuel where it's equivalent to using about 5% nitro in the fuel. For 4 strokes (with zero nitro) about 5% acetone has been found to work very well at stopping kick backs (thrown props) when starting. One minor plus with acetone is that it reduces the hygroscopic ability of methanol which could explain why Shell A racing fuel has 3% acetone added in their drums. "
This is from somebody going by the handle of " Downunder " . So may be a neigbour, statewise anyway , here .
Think what I mayve read related to the flashpoint & burn rate when combined / used in methanol .
It was the ' keep it alight ' which I thought could be usefull . Dunno if THAT was when I was getting it stopping at half tank thou !
Could well be . Maybe try only 1/2 a litre , to test . The WHITE GAS seems to be the tried & proven formular .
