Final night time, a buddy came visiting to assist me shoot some video. He needed me to crank over my 1986 Grand Wagoneer to see if it ran. I doubted it could, however I gave it a shot anyway. Whereas I used to be cranking the engine over, he picked up a can of beginning fluid. Large mistake.

From contained in the Jeep, I stored listening to the engine hearth each three or 4 seconds. “Hmm… that is odd; it looks like it desires to fireplace even on the 12-year-old fuel.” Then I heard a misfire and my buddy yelling “Hearth!”

“What the hell simply occurred?” I virtually had time to assume as I sprinted 100 yards into my storage to seize my hearth extinguisher. Fortunately, one other buddy of mine had joked about my Grand Wagoneer a couple of days prior: “Hey Dave, bear in mind, your hearth extinguisher is in your Willys,” so I knew precisely the place that crimson propellant-filled tank was.

I hustled again to my Jeep to see my buddy making an attempt to fan out the fireplace that was spewing from my carburetor. I popped the pin from the extinguisher, and commenced coughing as a white cloud of mud ended the drama.

My buddy admitted that every one these instances the engine was “making an attempt to fireplace” had been a results of him spraying copious portions of beginning fluid immediately into my carb as I cranked the engine. So primarily, I used to be flooding my motor with stale fuel, and he was hitting it with ether.

Anyway, now looks like a superb time to speak concerning the risks of beginning fluid. First off, by no means spray the stuff right into a carburetor whereas the engine is cranking. Ether is extraordinarily risky, so it’s not shocking when you get a backfire, and you then’re primarily holding onto a grenade. Spray it into the carburetor first. Then crank the starter.

And by god, be mild on the beginning fluid. I do know, it’s tempting to joke about “feeding the motor some go-juice,” however Ether not solely tends to combust violently (which may, theoretically, injury your engine’s internals), however even with the “higher cylinder” lubricant that’s in it, beginning fluid can and can seize your motor when you use an excessive amount of.

See that Suzuki GS550 engine within the image above? It’s been sitting on the shelf in my storage for a very long time, as a result of about 4 years in the past, I made a decision to spray beginning fluid immediately into the cylinders to attempt to get that candy Japanese inline-four to fireplace up. After it didn’t run, I went on a two week-long “sizzling journey” (I used to be working exams on the then-new Jeep Cherokee KL), and returned to search out my motor fully locked up.

No quantity of Marvel Thriller Oil may repair that drawback. I hung off a two-foot breaker bar, however that piston had develop into the sword within the stone; it was without end locked in place. Basically, the beginning fluid I had sprayed into my engine and left sitting for 2 weeks had acted like a solvent, wiping oil off my cylinder partitions, and inflicting my piston rings to “chew” into their bores.

That locked motor taught me a worthwhile lesson concerning the risks of ethyl ether-based beginning fluid, and I’m certain my buddy discovered a factor or two from my now-charred AMC 360 V8.

So yeah, for the sake of your well being and your engine’s well being: take it simple on the beginning fluid. In case your car’s not working with a light-weight squirt of “the great things,” you’ve obtained different issues that beginning fluid is not going to remedy.
