ok guys this might sound like a dumb ?. but i am in the process of rebuilding my motor 2F motor with a rv grind cam. in fact i got the complete engine kit from man-a-not so... my question is i'm trying to set up the valve clearance before i start the motor up following the procedure but when i get to #4intake valve i can take the adjuster all the way out and the push rod is still touching the rocker this also goes for #5 ex valve. i work on cars for a living and this is stumping me. its not like adjusting the valve's on my old 535, which is soo simple. also when i roll the eng over the valve clearance on the valves i just adjusted gets way out spec. AHAHAh its driving me nuts.
