    Hasn’t been cranked in 18 months. What do I need to put in the cylinders and for how long before attempting to crank? I’ve got the fuel issue taken care of. Thanks guys.

    If it had something put in the cylinders BEFORE storage you should be fine. If not look in the bores with a scope and check for heavy rust. If it looks ok turn it over a few times by hand and if it is smooth I would not worry about it and run it. Nothing you can put in them after the fact to really help. Sea foam will help with rings sticking and maybe a little rust removal but rust is not a good thing. CJ
