Hi have you gotten it to run as it should? If so what did you find?

If you still have the head off . You can put a small amount of water on the head @ the valves. To see if the water drains down in to the head. If it does . You need to do a valve job. too!

Mowed my pasture yesterday, with very little issue yesterday.  She does still sputter a little like running out of fuel on uphill climb, and I do need a new fuel cap.  Still not sure what fixed it, I wrapped the fuel lines with aluminum foil to help with heat, knocked a bigger hole in the gas cap, and it is now cooler here in NC.  Doesn't matter, I had a great time cruising along and very happy with the old girl.  

 

For you smart guys, can you have too much of a vent on the fuel cap?  I need to replace it because I am sloshing fuel out, but just curious.  BTW, I am willing to bet my problem all along was the vent causing fuel starvation, but I learned a lot about my tractor, and everything I did needed to be done anyway.

 

Thanks for all the help

If it's sloshing fuel out, it's to big! Get a new cap. The sputter could be the float isn't set quite right.

Dont waste the extra money for the cap with the fuel level gauge in it. The ethanol in the fuel will attack the glue and the top will come off, making a nice funnel for getting water and crud in the fuel

I know I need a new cap, just can't find one local and haven't taken time to dig around online. Thanks for the heads up on the ethanol and glue, very good point.  Also, I will check my float

Hi I'll see if I can find the numbers on a gas cap i got at the local farm store but any parts store has the size it will be all metal vs plastic, I've bought 2 with the fuel gauge and have had no problems with them and 10% ethanol fuel but they are not cheap.

I checked out the gas cap in the shop and it is a Stant 10623 and the one on the 73 PK is a 10640.
