Temps in SC PA have dropped into the 30/20 range. I am pleased to say the '97 has been starting with no problem. In Oct it was giving me problems in the low 50s. That turned out to be self-inflicted: I hadn't checked the fluid level of the battery and it was very low. Luckily, the battery revived by just adding H2O. (It truly is a Die-Hard.) The start-up procedure that works for me in mid-20 degree temps is the following: 1. Put the mc in neutral; 2. Roll it to break the clutch plates free; 3. Turn on the gas; 4. Set the choke to fully off (yes, off); 5. Turn on the ignition; 6. Hit the starter; 7. Do not twist throttle; 8. At first sound of engine starting, engage choke until engine runs; 9. Use throttle. I find that if I put on the choke or use throttle with the starter, it does not kick over. This mc lives outside under a DOW cover and I haven't made any adjustments to the carbs. I haven't had to use the truck battery to start it. I'll see how things go below 20 degrees. I am using a smart charger daily and I am starting the mc at least 5 days a week.
