OPT, do you know what the specs are as far as the Valve clearance, torque on the 3 bolts on the cam sprocket are supposed to be, and torque on the 4 bolts that hold down the rocker arms are supposed to be?

Thank you

Retrace your steps on the carb rebuild you did along with making sure fuel flow is good from the pump,if you're sure the cam is timed ok,valve clearance ok,cam detent spring hasn't slipped from the lever . If it was spitting before the cam install and still doing it,then there's something somewhere you've over looked.

What is my valve clearance supposed to be for both the intake and exhaust side?

You'll probably be upset with me, I ordered the cam and no rocker, my buddy said "you don't need that, your old one will work"

So my question is, how will I know if my exhaust rocker is bad? My exhaust lobe on the cam was completely gone, it was almost perfectly round.
Once again thanks for all of your expertise advice.

Look at the rocker pad where it rubs the cam lobe and you'll probably see why I said to order a new one! Everyone I got a hold of was scored badly..

Well, I got the valves adjusted perfect, started up, ran good, no popping. However, carb was leaking, took it off for the third time, had already rebuilt it, floats adjusted where they should be, still leaking. I also cleaned it, took the main jet out etc. The tab that holds the needle on the float, is that supposed to be bent up and clip on the float to hold the needle? One pic I saw it looked like it. Now it seems the starter is going bad. Every time I fix something another issue comes up. I already have some good money in it but I am about ready to part it out...
