An automatic tensioner is a spring loaded idler that provides consistent tension that can make up for stretching of the belt.

Since you need to add an idler on the bottom, now would be a perfect time to use an automatic tensioner.
X2.....if you can find one that's cheap and fits right, it would sure be handy.

realistically, installing one of those would be much more work than it is worth.
I have no problem tensioning the belt with the TB tensioner, so I think I will leave it where it is.

well, I have been driving it around some more and all seems to be good.
whatever made it stall has passed(my dad thinks it was the last bit of air working its way out)
it still misses a little when cold, but I think that is mostly because it has no cold start timing advance, and it is not bad enough to make it hard to drive, I just have to keep my foot in it a little right at startup.
I am getting used to the uncaged governor in a car(I have driven them in trucks lots, but never in a car) and it really does act just like a truck. starting out there is no need for throttle, as the governor will add fuel as you clutch out.
and it will accelerate to whatever RPM you have your foot at and then just stop, not like a gasser(or caged governor) that 3/4 pedal is 3/4 throttle, but more like full throttle until 3/4 of redline and then just cruise.
also when the RPM's are high, like cruising on the highway, the throttle under that RPM(like at 3500RPM the first half of the pedal travel) does nothing, and then it starts to accelerate after that.
it takes some time to get used to and to not automatically put my foot in it more on a hill(there is no need to as it just throttles up to keep speed)
I really like it, just different.

well, I just heard back about the shipping on the clutched pulleys, and I can get them for $44 plus $9 shipping!
any one else need one?

An automatic tensioner is a spring loaded idler that provides consistent tension that can make up for stretching of the belt.
I don't think you will be happy with the setup without the auto tensioner - Remember, there are 2 types of stretch and your manual adjustments can only compensate for one of them (The stretch that happens over time from the load) - the second is the stretch from acceleration. This one requires the auto tensioner. If you looked at the formula for what a belt can do, the tension on it is a factor, so if its not constant, you'll have shorter like.

I might look into an auto tensioner, but for the moment(as I am tight on time I can work on the car) I will stay with the manual adjustments.

got some goodies for the motor in the mail today!
the new 58mm charger pulley, a six rib pulley for the alternator, a diesel timing belt tensioner(the gasser one I hva tensioning the belt now is too narrow for a six rib belt), my new lower timing cover, the new water/meth nozzles, and a coupler to mount them in the intake.
also, I got the idle switch and bracket
I bought a new shorter six rib belt, just need to go pick it up later today.
now I need to find a place with an impact(to swap the alt pulleys) where I can swap everything over...

well, I went and got the belt, and decided to try and install the smaller pulley.
while I was at it I installed the lower timing cover
it turns out, however, that the six rib pulley I have for the alt is not only wider, but has more offset as well
so I need to remake the offset adapter for the alt to make up for this difference.
the one I made up was ugly and imperfect, and allowed some misalignment in the pulleys.
my tax refund just came in today, so I think I will go talk to the local machinist and have him make me one,
I took all the necessary measurements already, so it should be an easy thing for them to make for me.
so, slightly defeated, I left the car looking like this
hopefully I can get this done on friday/saturday and be able to drive it again next week.

well, I drew up a plan for the alt adapter for the machinist, should be pretty easy to have them make up.
I will take one of the bolts I will be using so they can tailor the adapter to fit them perfectly(my measuring tools are precise, but theirs are better)

oh, and I think I figured out my chugging and dying issue, it started doing it again whenever I accelerated or turned sharply, filled her up with fresh diesel(took 11 gallons) and all issues gone!
the gauge showed 1/4 when it took 11 gallons, so I just need to remember that it is not particularly accurate

Pull your in-tank pickup and make sure you don't have any cracks around that level. Even a small break will let you suck air if it's uncovered, which could be your problem.

I think MK1 GTIs had a similar problem with the fuel tank/pickup-pipe when turning hard left or something. Would cause the car to run lean and even stall.
