A few things that I've noticed that could have cuased the engine to stop mid flight.

So I took the carb apart I noticed two things. 1) Both bolts were pretty loose. I could have used my fingers to loosen one of the bolts. I noticed that no loctice is used. Should I use a small drop of blue loctice to tighten the bolts?? 2) Once I had the carb apart ('im giving up on finding a rebuild kit for now) I noticed that the small screen that sits down inside one of the openings had a TON of what looked like little tiny rocks but very very small. I took a can of compressed air cleand as much as I could. I didnt want to brush it with anything but I would say I got 99% of it cleaned. I also used the compressed air to blow out the other openings. I used some brake cleaner to clean everything while it was apart. I did have all the rubber diaphram and gaskets off when I used the brake cleaner.

I also found the following. I took the gas tank apart. 1) I noticed that whom ever built the tank before me used nitro fuel line instead of gasoline compatible line and used it it on the fuel line that feeds the carb. NOT GOOD the nitro fuel line had completley started to break down. The clunker had fallen off so I'm assuming that the fuel line might have been floating at top of the tank sucking in air instead instead of fuel at the time the engine stopped. I would have thought that I would have seen air bubbles in the fuel line when I was doing my preliminary test runs but don't remember seeing them. Anyway along with new fuel lines, spark plug, and new battery I think I will have resolved all of my issues.

Anyone recommend a good inline fuel filter for my gas can that fits medium size tubing that can be found at a local automotive store?
