As a rule of thumb... half of your spark plug gap. I have been doing it that way since the 50's with no problems.

I have a Texas T setup. The instructions say .015-.020 thousandths. It makes a very noticeable difference when set at .015 vs .020. Mine runs best at .015

Good luck!

My Dad always used a matchbook cover...single thickness for the point gap, and folded over (doubled) for the plugs. I never mic-ed a matchbook cover to see if it was ~.015 or not, but his "feeler gauge" sure worked for a good many vehicles!

That's quite a spread for a point setting. I can see how it would run differently from one end to the other.

The old Volkswagens specify 0.016"

Not that I would switch to a distributor. I like the buzzing of coils.I do have a question though. I remember VW Bosch disyributors having some retard built into them to reduce the overheating of #3 cylinder on air-cooled VWs. I can't remember the amount of retard. Are the distributors used in T's the same way?

I am quite sure all VW distributors for the Bug had a 2 degree advance on number 3. Number 3 was hidden behind the oil cooler and got less cooling air.
After getting the engine hot climbing a long hill and backing off the accelerater going down the other side the number 3 cylinder would be so hot and suddenly cool down from less cumbustion temp and the exhaust guide would cool faster than the valve and it would grab the ex valve and hold it open so the piston could hit it. I have seen dozens of bugs and busses that dropped number 3 valve.
Advancing the spark on that cylinder was thought to make it run a little cooler. Maybe it did, maybe it helped.
VW bus guys would get a good run at a hill and ease up a little just before the top and then accelerate a little when starting down the other side to keep the engine from cooling too quick.
That should not have enough effect on the T engine to make difference.
The problem came when the distributor was in a half turn off and numer 3 lobe was firing number one.
So when you set the timing on number one cylinder that made the other three 2 degrees retarded. That caused a stumble on low speed acceleration.
So get a distributed cam from a type 3 VW,
I never noticed a problem with that when using a Bosch distributor in a T.
