I found a new starter on eBay for 54 shipped to my door l I also have a purolator pro 42s electronic fuel pump that is rated 1.5-4 psi its new that my grandfather gave me so I think that it'll work perfect it has a built in piece so no more back drain out of the carb.
Same pump as one some of mine now. That's a dirt low price on that starter! No matter if fuel drains back, 2 seconds with key on & pump fills the carb.
That's why I love electric pumps.
