Backfire Damage!!!!

[Recon1504]

I decided to get LC2 running today, clean the snow/ice off her, and put her back in the barn where she belongs. Well, I had pilfered a few parts off her when my points broke on LC3 so I was putting them all back on today. The dist. had been pulled so I could use the distributor clamp on LC3 (I broke the other one-long story). I had marked the position of the rotor and the position of the dist body before I took it out. I got everything reassembled and figured I would start her up and move her inside. Usually she starts up with a couple of turns of the engine. I gave her a little choke and she didn't want to start so I continued when-BANG (thought I was under mortar attack for a second). The loudest backfire that I have ever heard-completely engulfed LC1 in a black cloud of smoke. It blew a big hole in the snowdrift that was near the tail pipe. I looked underneath and the muffler was puffed out , buckled in the middle,and the front of the muffler was opened up like a sardine can. It even blew off lots of chunks of old undercoating/rust for the immediate area. Well, so much for the lifetime warranty from Midas.

Moral of the Story - Don't take shortcuts with timing-get out the book and do it right the
first time.

Had that happen to me one time while roll starting the 40, peeled the muffler apart and made my ears ring for a good 10 minutes...........................

muffler

I did the same thing on purpose to a old POS moving truck from a not to be named source.

Long story short I made my reservation for sat. 8am. It was to be a college move with five guys, 5 hours max. Showed at 730am and was told to wait. We finally left at 1030am for a full day of moving. The jersk gave my truck to a guy with more $$.

This was before everyone had cell phones and the new place had no phone hooked up. I lost two of my helpers when we were late (they went to work).

I was really pissed. Later that day I fast idled that 1970 F350 beast with a moving box down a long steep 4-5 mile hill in my town. A group of local skater hoodlums had gathered in their usual spot at the base by the gas station. I turned it off with the key about 1/8 of a mile shy of the skateboard dudes. Right as we passed I fired it back up. There were three guys sitting side by side in the cab. We nearly pissed ourselves laughing. Every single skater hit the deck. They thought they had been drafted right into the gulf war.

We stopped later for gas and I peeked underneath. That muffler was blown flat to the bottom of the moving box strapped to the frame. We still laugh at that one some 15 years later. Never seen anything like it.

Just had to share a story from the good old days.

dirt pile I almost feel proud in a redneck sort of way. My compost pile is more along the lines of redneck hippy though
