It has a #42 squirter in it now. will it hurt to put the 50cc pump on it? I already have it.

I spent the night looking up all the parts in the holley carbs and how and what they do and then tore a spare down that I had in the garage. I have a basic knowledge of how it operates now. I'm going to order a 50cc accelerator pump to replace the 30cc one. I'll order a new powervalve (2.5) and...

Well I just dropped the motor in and only have a few hundred miles on it. I didn't really notice it until recently. I'm sure its been there all along but I'm just now getting into the fine tuning.

I had originally planned on reusing the stock fuel pump that came with my 440 motor out of a new yorker. But now I'm having second thoughts. I'd hate to drop $200 on a new fuel pump if I'm not going to notice any differience. Should I run the pump thats on it now, buy a new $40 cheapo one, or...
