Here's a pic of the engine from my '76 TR6 (sold). When I finally got it started I heard a "ping" coming from the engine that drove me crazy trying to tract down the 'ping". After doing a leak down test I decided to pull the head. Here's what I found :scared:

One of occasional posters here has a Lotus Elan coupe. Long time ago after a bit of work on the Webers, it was off for a test run and within a few yards the engine started making some unpleasant noises. They pushed it back to the garage to investigate, determined the rattles were coming from inside the engine. Head off and found one of the 8mm nuts securing an air horn to the carb had come loose and found its way into a combustion chamber. Embossed in the head were stamped impressions of the nut. Nasty! All those nuts were replaced with Nyloc ones. And on every Weber ever touched after that.

The seller that I bought the car from never worked on his car. In fact, he wasn’t capable of it. He told me that he had “mechanic” do all his work. Well, I bet his mechanic dropped that lock washer into the intake and never told the owner.
 
Back in the mid 80s when I was about six and my dad was teaching me about carbs, the first thing he'd always do when yanking one was to stuff a rag into the intake and when reassembling a carb he'd use a toothpick and apply a drop of loctite to the threads of all the carb screws. He told me back then that I never wanted to lose anything down the intake.

I recently had to pull the intake manifold on SWMBO's BMW Z4. The first thing that happened as soon as it come off - rags in the holes!
 
In the early 70s, my BSA Starfire 250 ate its top piston ring, a little bit at a time. The engine would catch and hesitate for a second, then I heard a tinny rattle as each piece worked its way down the zorst. The very last piece embedded itself in exhaust valve seat, holding the valve open.

Were you able to salvage the engine?

One of those "Oh, FRELL!" moments. One of the first things that goes through my mind at times like that is: "Now what's THIS gonna cost me?!?"

Many MANY moons ago a college dorm mate volunteered at the Canadian Warplane Heritage Museum - they forgot to remove one rag from the intake when starting a fresh engine - they apparantly retrieved it and framed it with the title 'the $50,000 rag'

Back in the late 60's, my Fiat 850 Spyder was running poorly.
My friend offered to rebuild the Weber at the gas station he was working at.
I had no skills or money to pay a shop, so how bad could it be.
The car ran great for a day or so but had a nasty ticking sound.
I had to ask my dad to check it out and he found four lock washers embedded in the piston tops.
A couple of the pistons had holes through the tops.
Fortunately there was an 850 engine nearby that I got for a song.
Lesson learned, you get what you pay for.
