RE: Engine balance, How to ?
Nick,
Your glow fuel costs are reduced. Most Americans pay about $9 per gallon/$2.50 per litre for glow fuel) and only $3 per gallon of gasoline.
But even then, glow fuel is consumed at a rate over 2.5 times higher than gasoline, so even for the cost is higher.
Methanol has a stoichiometric ratio (best power) of about 6:1 and for gasoline it is 13:1. With methanol is it eventually higher, since 20% of the fuel is added oil.
So, it is about 4.8:1
In another thread I set my limit at 26 cc/1.60, where the use of gasoline overcomes its disadvantages.
With electronic ignition, you don't need that huge magneto and coil; just the very small reluctor/pick-up and the system, of course.
