Every time I bring a pump/car back from the dead I put my battery on the charger and use my diesel carrier electric pump, with a temporary cheap clear hose(with cheap temp filter) for the in and out lines into a bucket.  This can let your run a pump without having to worry about the air intrusion, dirty filter, etc.  Also the pump will let you run it in case the vanes are gummed up and it cannot pump on its own and it will save your starter and battery :)

Starter is another big one.  You want to spin the car over fast, you could have an old one that might do the job on a healthy motor.  For whatever reason every shell I have got has been weak in the starter department.  Like cranking for 10 seconds and then having it slow down.

Somebody on this forum sold me a tdi starter from a 2000 model auto trans and I really like it.  My car starts up practically instantly hot or cold, I can't count the revolutions.

Alright, changed the filter and gave the primer bulb a few squeezes while holding full throttle. Start reving nice and strong. Drove around the block, good power.

Only problem is revs hang real bad after giving it the goose. And with 56hp, you use a lot of throttle, a lot of the time. Seems like over fueling to me, but the collar is still on the smoke screw, and the yellow paint marks from a rebuilder are still intact. In neutral, when you give the throttle a stab, small puff of black smoke. When idling, and when the revs hang, no smoke.

Rev hang means that the fuel screw is in to far.  Black smoke means too much fuel as well.  Back it off a half a turn, adjust idle if necessary and see how it works.  No more hang, good if still hangs try another quarter turn out.  You are just wasting expensive fuel.

The fuel screw didn't want to turn, but didn't have a 6mm wrench. Rachet wouldn't fit, and flat head couldn't put too much torque on.  The collar shouldnt stop it from coming out, correct?

Hit it with some penetrating oil for a bit and get the vice grips on it.  You need a good snap to get it loose and a 6 mm is probably not going to get the job done.  Will slip right off.  Use it after the screw is loose.

Dont damage the end threads, or wreck the hex while your wrenching on it!

Cracked it open, went back an 1/8 of a turn no more rev hang. Once I drive it, I will watch the smoke screen and see it it needs a bit more.  One of the delivery valves is leaking, and it "dieseled" a bit as well. Getting real close to on the road.
