TEA Water Pump/Generator/Carb Questions

I got back and felt all the hoses from the rad/water pump. The upper hose was very warm the lower hose was room temperature, is this normal or is this a sign of a faulty water pump? The thermostat has been replaced.

I took a voltage reading from the leads at the generator and I measured 2.5 volts. I know this is way too low, is their anything I can do to increase the output voltage from the generator?

The engine is running very rich when I adjust the upper screw on the carb to lean it out , it doesn't seem to do anything. To complicate things the engine is hunting so the throttle position is constantly changing. I've read on this board that the govener adusting screw is very delicate and I would rather avoid touching it if possible.Can I ajust the carb under these conditions??

Turn that one in 1/8 at a time until when you knock the throttle open under load you JUST do not get a puff of black smoke - then your mixture will be right. Do not go too weak.

Sort the carburation out before adjusting any of the throttle/governor linkage.

Re temperature, I would say that was normal(ish) after road use (not much load) the radiators on these are designed to handle a massive cooling load, so if your gauge reads OK, and nothing is boiling out of the rad, don't worry.

Can't help much on the electrical stuff, but yes, you should be getting more than 2.5 volts out of the generator - are you sure your field coils are connected and working and that the brushes and commutator are fit and healthy?
