johnny i know with my mud truck it was a pain to get and keep her running right. think part of my issue was a bad fuel pump that allowed fuel to drain back to the tank after i shut the engine down. i installed a universal electric pump from napa, for get the psi but it was around 5. good number for a carb. i have it set up so i can flip a switch and manually turn it off or on but also have the power wired to the fuse box so it only has power with the key on. it got rid of most my issues after a good tune and the pump installed i can have the engine sit for a year. put a good battery in her flip the switch and turn it right over and she starts every time. i also have one of those plastic boat fuel tanks that i remove when im not using the truck just so the fuel doesnt sit and i use it on other engines
