Torque spec for valves ?
I presume you mean valve clearances .
Why do all the hard stuff before the easy stuff ?
Won't start the next day No 1 will be to try a brand new fresh plug with some brand new fresh fuel.
that generally does the trick.
Any way you are there now so this is where to find what you need to know
Cub Cadet Professional Shop Manuals
Book mark the site they are really good for parts provided you want original Cub parts
or
"K&T Parts House Lawn Mower Parts and Chain Saw & Trimmer Parts"
Slightly different manuals with clearer images and a good place for aftermarket Cub bits
I have trade accounts with both because Cub Australia won't sell me parts and the agents actually charge me more than retail so I get my bits from the US for 1/2 the local wholesale price ( used to be 1/3 but the $ Aus has dropped a bit )
