Default Winter Cold Engine Starting!

I'm going to start doing something that I've never done before. Winter flying. OK, those of you that live in the northern tier, what's your secrets for starting and keeping those cold 2c engines going in the cold winter. Over!

I squirt starting fluid (ether) in the carb before I crank the engine. I've been told that WD-40 works equally well.

PS I have good luck with 20% nitro in cold wx

I have heard stories of flyers pouring hot water over the engine head first! (maybe I just saw it in a dream)

Just hold the engine at the exhaust of your car (with car running of course) for a few minutes to warm it up.

Don't know if it's any better than ether (starting fluid) but we use lighter fluid. Just a dab will do ya.

Why don't you just prime it a little more and start it. I fly when it is very cold and that works well. Use 15% fuel. Never had a problem starting an engine in the cold. leave the power to the plug a little longer to warm it up and it works fine.

Thanks guys! Hey Flyboy, wouldn't the additional nitro make the engine run colder?

Default Nitro

Adding nitro cools engine operation is a common misconception in this hobby. Adding nitro will help in colder weather.

The best thing I've found for starting cold engines is regular gasoline. Get a bulb from sullivan and squirt a few drops in the carb and it will start like a champ. Lighter fluid works ok but gasoline is the best.

Default Gasoline

Oh, I almost forgot, adding gas (not to exceed 5%) to your fuel will help it run hotter in extremely cold weather and help it start quicker.

I added gasoline and acetone to my no nitro mixtures and it helped keep the plug lit.

Ya you know the stuff you put in your everday driver, lawn mower, or what ever. I'm serious it works great no joke.

Just use normal saftey measures and common sense. If you have a helper to feed in the gas this is best.

If nothing else works at -20 windshield temp gas will. Believe me I was thinking what ? gas? when an old timer from our club showed us this trick we where amazed. The engine would start like it was 90 outside. Give it a try it's a lot safer than holding the engine behind the tailpipe of a car or truck. Have fun with your winter flying.

BTW our frozen fun fly is coming up on Jan 1 and believe me I will be using gas to start my engines. Have fun!

Will using this technique damage the fuel tank or tubing?

I think he means: "If nothing else works at -20 degrees windchill, gas will work."

Remember those heating pads for sore backs. Connect them to one of those fantastic converters (12v to 120v) - available at stores like Canadian Tire Store up here in Canada and and connected in turn to a 12v battery will keep your engine warm to summer temperature. Engine well primed will start like in summer.

Hi, for some years I flown in the winter, -5C, strong Wind and Snow. I take a propane gas burner and i make the cylinder and the head worm. Attention, don't burn your model. My model was a delta and the engine a 6.5ccm Webra. Ok, its crazy but its real!

I just make sure mine is primed well, then use the electric starter, and off she goes!! But I do leave the igniter on a little longer till it warms up a bit... 15% works fine for me.. I use the same in the summer.

I watched a guy use a heat gun (for covering) yesterday. He held in near the cylinder for about 20 seconds. Started perfect after that.

We don't have 110 v at our flying field, but good idea! Thanks.
