H troubles

Hello, I had just got my restored 1942 H out for the first time this year. Before I restored it last year it ran perfectly. I noticed that now the fan or something in the front of it rattles. It is not in the engine but in the water pump or the fan. Could it be the spring that holds tension on the shaft is weak or not tight enough? Could the fan blades be lose from each other? Any help you could give would be greatly appriciated on this. Also the tractor loads up when idling. It did not do this before I restored it but after it seams as if the tractor is getting way to much fuel. I have tried to adjust the govenor and the throttle linkages and the carb but no luck in fixing. Can anyone help on this or give me the stock specs to start with for the govenor screw and the throttle and the carb? Again thanks everyone for your help!
 
Diagnosis of the fan hub should be one of wiggle motion, and noise. If it does not wiggle when flexed with the fan blades (stopped)
Noise can be spotted with a short broom stick or other stiff rod touching the Water pump body and listening to the other end. Be careflu to not touch moving parts!!!
You might have a leaky needle and seat in the carb letting gas in just enough to load the engine. Removing the bowl and flushing the seat with carb cleaner might help. The idle adjustment procedure is in the archives!! Search for Box

If the needle, seat, and float look good, check the idle circuits. Any gas in the carberator when you stored the tractor may have turned gummy and plugged up the idle passages.

The usual symptom of plugged idle passages are the inability to adjust the idle.

All good info! Also check for a loose fan shroud! I had one loose bolt on mine and the intermitant rattle almost put me in the nut house ( I am usually almost there anyway)! Just another area to check. Good luck!
