So I recently purchased a 1959 international 460 utility tractor. I thought it was a fair price. Has the loader on it. I knoq the PTO needed sone work but i had started it up a few times and it idle and ran fine, before i bought it. Afteri bought it, and changed the battery, it would start and run in low gear but wouldn't open up. Then it started stalling. Listening to the farmers at the auction i put sea foam in the gas. (I dont have alot of mechanical experience but im not afraid to try and fail.) Now it will crank but wont start. I cant load it cuz it wont run. Any suggestions or tips to get it runnibg so i can load it get it home and them do deeper diagnostics and repair?
