No Smoke When Fogging

[obeejr]

I have noticed the last couple of years that when I fog the engine by squirting fogging oil into the carbs, not much in the way of smoke comes out the exhaust.

To be sure I've used enough fogging oil, this year I sprayed almost an entire can into each engine. I say almost, because when the can gets low it doesn't spray well when tipped into the carb.

As with previous years, I saw little smoke from the engines.

When I fogged my genny, it smoked like a four alarm fire.

Am I doing something wrong here, or is it the nature of newer engines not to smoke that much because of the electronic ignition or some other factor?

If you're doing it alone, that's all you can do. If you have help, use two cans at the same time. George has told me your goal is to choke out the engine with the stuff. Squirting with two cans will do that. Also make sure your idle isn't too high - it's probably fine.

What I've done in the past is after running the pink, I've pulled the flame arrestor, pulled the wire from the coil to the distributor and while turning the motor over, sprayed the fogging oil down the carb for about 5 seconds. This gets the oil into the motor just fine.

Actually, I used two cans, and sprayed enough into the primaries to stall the engine after about 10 seconds.

Still, no smoke.

I've pulled each spark plug and sprayed fogging oil into each cylinder...cranked the engine over a couple of times and called it good...
