Hi all, I have a Ferris 1500z with a 21 HP Kawa FH641v. My mechanic told me to order a new head-cylinder#1..I did so from mowpart.com, but head did not come with valves, springs, ect. My mechanic told me they always come complete. Web site states HEAD-COMP-CYLINDER,#1 part # 11008-7024...wouldn't the "comp" stand for complete.? Is this a mistake, or is this the way this part is suppose to come?. What other parts do I need to order? the schematics page on mowpart.com doesn't list any springs, ect. I'm confused..please help.
