Fogging Oil

[Buccaneer]

I learned by accident today that fogging out can be used to start an outboard!
I sprayed some in each cylinder of the Firestone, put the plugs back in,
and the wires on, and was just going to pull the engine over to coat the cylinders,
and the bugger started and ran for about three seconds…… wasn’t expecting
it to start! Used it for years "summerizing" my snowmobiles, but of course
the kill switch was always off.
Looked at the ingredients, and there’s propane and butane in the fogging oil……
propellant I suppose.
I was my first run of the Firestone since I’ve owned it….. those three seconds
sounded really good, lol

Prepare to be boarded!

Yeah, Ive started a few motors in the basement by mistake 😉

I’ll never forget the time I had a TD-20 on my service stand. I was soaking the cylinders in SeaFoam overnite to help soften up the carbon. The next day, I pulled on the starter and the motor started up and ran for about four or five seconds. Heavy smoke filled my basement from the floor to half way up to the floor joists. Oops 😯

Funny Aquasonic……….. glad my Firestone was in the garage!

Prepare to be boarded!

They’ll fire up on WD 40 to!

A fun alternative is removing the plugs and replace them in the sparkys . Then hold them in the vicinity of the holes to check for spark , thereby creating a double barreled flame thrower when you rope it over. Doh 😳 😆 !

And let that be a lesson to everybody. I darn near set myself on fire that way. Had a spark checker set up and hit the remote starter button. Turned out the engine was "flooded" and gas shot out of the plug holes and the spark checker ignited it. Flame shot out about 6 feet, right past me. If I’d been standing another foot toward the rear, I wouldn’t be writing this today.

I did the same thing as Frank, using a spark tester on a 4 stroke Honda. Turned out it had a fuel leak on the pressure side of the fuel pump. Once I cranked it and built a little fuel pressure, oddly enough the location of the leak allowed fuel to squirt directly on the spark tester. A 3 ft. flame erupted, that I had to hit with the fire extinguisher. I then spent the next couple hours cleaning up the mess.
