Here we go again. Had this issue a few weeks back. Replaced bad plugs, changed aged battery, put new voltage rectifier as I was getting 18 volts at battery when idling. It's plugged on a Noco 2amp tender when parked in the shed, it's -20c here today. Took it for a spin 2 nights ago. Didn't fire up like it usually does and had a hard time getting my idling rpm above 1190 without it jumping up like crazy. Now today won't even start. I rolled it in the heated garage to try it again later. Any ideas. That rpm thing is bugging me

Fuel stabiliser should help right I try to always run mid grade gas in it

Drain and flush the tank and fill with non-alcohol real gas. Forget the stabilizer unless the machine will sit unused for extended periods of time.

If you use uncontaminated gasoline, stabilizer is unneeded unless it is going to sit a year or longer and even with stabilizer the fuel should be drained and fresh put in. I just drain my fuel system when I park the vehicle as I don't know if my next ride will be next week or next year.

BTW, pure ethanol freezes at 170 degrees below zero F. - if your fuel tank is 1 gallon capacity and has about teaspoon of water in it (1.66 ounces of water) and you add 2 ounces of ethanol, you will lower the freezing point of the teaspoon of water to about -40 degrees F.

Gasoline that contains 10% Ethanol is 12.8 ounces of alcohol mixed with 128 ounces of gasoline which yields 140.8 ounces of liquid. In a 1 gallon tank that is filled with gas-o-hol, there is 115.2 ounces of gas and 12.8 ounces of alcohol. 12.8oz of ethanol mixed with a teaspoon of water lowers the freezing point of the water to appx. 80 degrees F below zero.

Another thing; it only takes .4% of water to alcohol to make the ethanol in fuel separate from the gasoline. A teaspoon of water in 12.8 ounces (10%) of alcohol is only .2% of water to alcohol by volume, so not only a teaspoon of water mix with the alcohol in the gasoline, it will not cause phase separation in a gallon of fuel and it will not freeze at -70*F.

Myth dispelled!

Wow thanks for that breakdown. Much appreciated. After a but more head scratching and scrolling through the service manual I took the throttle cover off and checked my spacing ( I had screwed around with the adjustment screw to get it to idle at 1220). I guess I took it too far . Once I readjusted it's fired right up.
