Hello all, hope the holidays seasaon finds everyone well!! Quick question regarding Langdon's HEI... I know there has been a number of discussions on this already. The question, do I need the mechanical advance on this distributor. I read a thread where Marty didn't use mechanical, just vacuum. What is your experience. The reason I'm asking is the HEI I got from Langdon did not have springs on the weights. If I don't need the mechanical I will just tie wrap them...if I do, then what do you recommend as far as spring sets go?
Thanks
Todd
