Model Forum / Radio Controlled / Land Models / April 2004Any tips on starting a cold engine?
Any tips on starting a cold engine in a cold day (10 degrees Celsius)? Warm it with a hair dryer or car heater. > Any tips on starting a cold engine in a cold day (10 degrees Celsius)? Add 5% propylene oxide if the temp is below 45-50 F. Works fine. The oxide will evaporate quickly from the jug at around 70 F . > Warm it with a hair dryer or car heater. > > > Any tips on starting a cold engine in a cold day (10 degrees Celsius)? > Add 5% propylene oxide if the temp is below 45-50 F. > Works fine.

I hate to sound stupid, but what is "propylene oxide" and where would I find it? You are not stupid at all, you are just a modeler wishing to know what the liquid is. "Prop" is an "ignitor" that is added to Glo-fuel for enhanced starting abilities when the temp is in the range I mentioned. At these temps the fuel is slow to vaporize so adding the Prop will allow the engine to start running. It is similar to using "Ether" starting spray in your carburated auto engine on cold winter mornings. It will also keep the plug lit and steady the idle. I have a 1 gallon glass jug of it that's several years old. Try calling corner Drug stores to see if they carry it. Another source is photographic supply houses and chemical houses. At this time I think it is not available in 100% pure form in the USA, it's diluted 50-50 with methyl alcohol. It has a bad side effect of causing aggravated engine detonation if you use more than around 5%. I sometimes add a 1/2 ounce or so directly to the models fuel tank, just before cranking rather than adding it to the fuel jug. The stuff is $17-25 a gallon, so I don't waste it if I think the day will warm up. > > Add 5% propylene oxide if the temp is below 45-50 F. > > Works fine.

Keep it inside until you want to start it. I've heard of people putting cotton or aluminum hats on their cooling heads to keep the head temps up in the normal range. Otherwise hte head won't expand and it will scrub away at the "pinch".

David, if you're talking about your TGS, it should just start fine at that temp. If anything, it should possible start even better. If you are having trouble, check what plug you are using, and maybe try some others. Make sure your warmer battery is up to scratch. Make sure you've got at least 10% nitro. It should start fine.

Cold air is more dense, meaning you'll have to run the needle[s] richer to keep he same air/fuel mixture.
