Hey all, I'm going through my carb on the truck...basically doing a home job rebuild. I've got my carb apart and I noticed a couple of things that I am curious about. It's a Rochester B, 235 base/model, manual choke for reference.
My first question is regarding the accelerator pump. I pulled the accelerator pump out of the carb housing and there was no check ball present at the bottom. I got my flash light out and saw that there were to small holes at the bottom 180 degrees apart. I read that if the carb has these 2 holes, there should be an 5/32 aluminum check ball at the bottom of the hole. I'm pretty sure I'm going to need one in there, but I can't find anybody who sells an aluminum ball in my area. Is there a reason why it has to be aluminum? Can I use a steel ball instead? 5/32 steel balls are available at my local fastener shop. If I shouldn't use steel, then I'll order some aluminum ones on line.
Second question pertains to the needle in the carb. The needle in this carb is all steel, and I've been looking at the rebuild kits and it seems like they all have the needles with rubber tips. I'm thinking the needle in this carb is probably the original? Is there a benefit to replacing the one in the carb with a new one with a rubber tip or am I ok or even better off running it with the steel one?
