Lighter fuel in four strokes

       Remove this ad - become a site supporter!
This year I was given a tip for hard to start engines in the winter cold. A drop or two of light fuel in the carb and bingo. I have been using this technique on my 2 strokes but I am about to bring out my older OS 91FS and I was wondering if the lighter fuel trick is okay with a 4 stroke.

It will probably work but the engine would need to be inverted for the lighter fluid to get to the intake valve.

Just remember that there isn't any lubrication in the lighter fluid.
So don't over do it.

Could you please explain what is lighter fuel?

Is it a Kerosene base fuel like BBQ lighter or Zippo lighters?

Where could you buy it.

I have been using Zippo type lighter fuel this year. Remeber, it only takes a small amount. That means about 2-4 drops into the carb after you have already primed the engine normally. I say to prime it because the lighter fuel has no lubricating qualities and a good priming of glow fuel will provide the needed lubrication. Becareful not to flood the engine.

On 1st of this year's Frozen fun fly my Beaver's OS 46LA diden't wanted to start nornally, so guys at Mississauge Field used this Lighter trick to get it going initially, its worth using it in cold tempartures, but since then i diden't needed to use it again...

for winter flying try the following:

Get a can of car starter fluid ( diethyl ether) - 1 shot in the carb and you'll be firing away.

You can also blend a couple percent of gasoline in your glowfuel which will make your engine run and start better in the cooler conditions.

I also experimented adding the diethyl ether to the fuel which also worked well. Only added about 1/4 % and it made starting much easier. Ether is quite volatile compared to the other fuel components and adding too much will result in preignition.
