Ok. John Deere guy here. I have a 46 wc that we pull in antique pulls. It has had the head cleaned up a valve job. New sleeves and pistons. 4.125 pistons. Only has 11.2x28 tires. How can I gain some more hp without going back into the engine? Definitely think I should gain some rpms. Any info is appreciated! Thank you
 
WD45 manifold and carb and install a D17 governor spring. D17 spring w/ WC governor gets you about 2000 rpm.
 
What crank/pistons do you have? I'm a long ways away from pulling pro but to gain much I think you are going to have to add cubes. Also need to play with the rules where you pull. Do they have any RPM limits you need to be aware of?
