Well i finished my tune up on the B-18 with as well as rejetting the Weber with jets i machined and bored out myself....runs better than ever. but i found i had no mechanical advance....i tore into the distributor and found both springs broken on the ends. I made new loops and it definately improved the performance but its still not where it needs to be. I am planning on finding another matching distributor and throwing the best of both parts into one. Are there other distributors could i go with (not a new big expensive one)?
