Yeah those bugs were POS for sure. I worked on one about 20 years ago. I had to change the plugs on the beast. They came out with some of the threads. I still managed to put new plugs in but when I tried starting it, it went bang, bang, bang, bang. All the plugs shot out like missiles. The manager of the shop was standing there watching it all happen. It was the funniest thing he ever saw. I had a good laugh as well.
