Hello all just wanting some advice on this poulan motor i pulled from an old 33cc chainsaw today. Runs pretty darn good and looking to use it for my airboat build. When i took it out of the chainsaw casing i had to take the cylinder off the piston to get it out of the plastic, do i need to reseal it? Also it has what is referred to as a spring carb i think, can i upgrade to a walbro carb? Does this look to be a good motor to turn a prop and has anyone used one before? Thanks guys
