I am new to this forum but use IH and JD forums a lot. Just purchased an older Cub Cadet with mower and snow plow. On the left side of the tractor part, above the mower deck, it says model # 146-653-100 I can't seem to find that on Cadet site and looking for Operator's manuel. Also guy I bought it from said he was running it and ran fine, shut it off and wouldn't restart. Seems to have fire at plugs, fuel looks and smells kinda old. Very little pressure on fuel above fuel pump, and minimal flow, but plenty below it. How much pressure should fuel pump have? thanks for any help on motor and also finding operator's manuel.
