Dist. cam

[Keith]

Who is carrying (vendor) the best distributor cam which the points ride on.

 

[P.S.]

Most of the Model A parts vendors carry them. It is part #A-12210. The ones sold by Bert's are pretty spot on as far as lobe timing goes, but require polishing if you want the points rubbing block to last. https://modelastore.com/index.php?r..._id=4229&search=Distributor+cam&category_id=0

I would polish any cam you buy to a mirror finish.

Use the Model B distributor cam because it has a smoother profile for extended point rubbing block life.

Agree with P.S. and nkaminar about polishing - I ended up returning to an old original cam on one distributor because the rubbing block wear was so bad.

Yep. Scroll to about 4 minutes in to this video to see how- https://www.youtube.com/watch?v=zC4GW-vHjtg
