Mallory YC Model 11A: Customer sent this one in for a evalautaion. Didnt know if he wanted to purchase one of our new Mallorys for the Model A or use what he had. I ask him to send it to us and let us decide for him. This is what i got in the box. Points were just thrown in , incorrect condensor and damaged drive shaft coupling??? The metal in these old units is pretty good. and usually has a light rust coating and some crud preventing the advance opersaion. So lets clean er up and then take another look. WOW cleaned up just great , even the contacts were new , just greasy ( a trip to the ultrasonic cleaner and they are great). Reassembled with a fresh coat of clear and some spray lube . Ran on tester unit has a 20 degree advance plate and thats at 2500 rpm.
Works like a champ. Put another 10 or so degrees on the balancer and you got your 30 degrees. Has that old school look....
This worked out to be quite a bit cheaper than selling him a new one.....
This rebuild runs $250 assuming all the parts are useable!!!!!
As of February 2018 we no longer offer a new Mallory Model A unit. We have built a few hundred and no longer have the cores.....
I have many friends with Model A's and four cylinder engines. Problem most just dont have a clue as to how many degrees of ignition timing they actually have.
Most just set the pin, adjust the distributor cam and live happily ever after! Thats fine until we start the addition of a high compression cylinder head, a modified ful system and a engine rebuild.
The Model B distributor uses a full mechanical advance providing 20 degrees of mechanical advance at 2500 rpm and they work very well but can be a little difficult to source and find .
