Total and complete bummer. It is indeed a sad story. I hope you had a
fire extinguisher on board.

Most DCOE spitting on new applications can be traced to the ignition not
being advanced enough. A fully mechanical ignition system needs more
initial advance than a vacume +mechanical advance system. In the four
cylinder TRs this seems to mean 10 to 12 degrees initial advance.
Also if your fuel pressure is too high you can easily overwhelm the
floats and dump too much fuel into the carbs. DCOEs like 2.5 lbs
pressure max.
You want to set your float level to the proper height for your carb as
well.
DCOEs require air horns of some kind to get proper air flow into the
throats.
Your fuel out the front could be caused by any number of things or
multiple things at one time. My first guess is that you set the initial
timing per the TR book for a stock engine and maybe had at least one
other factor involved.

Total bummer. Having gone through a complete rebuild myself I
sympathize. On the other hand, maybe your story will convince me to get
around to plumbing the tubing for my in the box halon system.
Take care, rest until you can face your engine bay again the get back to
work.
