Slant six dies in gear

i'm reading this as: it was over heating, so i did all this. but that didn't fix it so then i did this, and while i was there i did this, this and this. but then it wouldn't start, so i did this. then this and this. well, now it starts and it runs pretty good but it dies in gear.

there are a LOT of variables here that are going to make this a difficult basket full of snakes to untie. carbs and distributors on and off, parts interchanged and intermingled, other parts substituted. none of this is conducive to an effective repair.

but! it runs, so you're on the right track!

at this point, i'd go back to basics. verify the timing chain was installed properly, check and set the valve clearances, check for vacuum leaks, reset the timing and carb to factory specs. if you can borrow a known, good carb for testing purposes do so.

get a copy of the FSM and a vacuum gauge, they'll be extremely helpful in diagnostics and tuning. there are some very sharp people here, answering the questions that they ask will help everybody get a better picture of what's going on.
