Whats the best way to break in a rebuilt 12A?

 

Here's my thread on this very topic:

I ended up driving 1000 miles keeping the revs under 3000. Then I went the next 200 keeping it under 4000, 200 more keeping it under 5000, another 200 keeping it under 6000, then let 'er rip. I have over 2500 miles on it now, and so far it runs great.

Varies with the new parts used in the rebuild. Old housings, (with new apes seals) and/or new bearings lengthen the break in. There are many opinions on break in. Generally, 3-4000 rpm for the 1st 1000 miles, the increase 1000 rpm the next 2 500 mile periods.

Change oil at 200-500 miles, again at 1000, then every 3000.

 

I have had to tow it to start it as the starter has fired it only once, the trailing plugs usually foul with the starter. I run it for a while to get it to temp but have put less than 50 miles driving it.I put a rebuilt carb on it and there are no vacuum leaks. Is this typical?

 

Nope. Mine fired right up after the rebuild, once we got the distributor in right. Check your timing, and the mixture on the carb.

how do you get the dizzy in right? I just put the leading mark on the notch and put the dizzy in, thats what my manuel said to do.
