Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Welcome to JUST ANSWER small engines, let me try to help you !! I don't know it all, but maybe together we can get you a satisfactory answer!
model number? Engine model? Is pump a drop in, that goes in corner of block, or a shaft driven pump? pictures?
If it has the drop in pump, it requires no setting. Just replace it with the same gaskets/shims under the base, that is what sets the timing, and you are ready to bleed and start.
I see question is still open, did you see my response?
