Stuck valves/Stuck cylinder head

Just thought I would waste every body's time, with a quick hint.

Freeing stuck valves and heads so you don't need a hammer.

Tools req:- Plug spanner and about 4' of about 5/16th diameter non hairy nylon cord.

Method:- remove plug/s, rock bike in gear until the piston/s are about halfway up on compression stroke, feed the cord into the bore (keep at least 1 foot in hand) now rock the bike forward and the bunch of rope will either A. push your valve back into place, or B. will push head off depending which you are trying to do. You will probably still have to locate your pushrod unless you are seriously lucky.

Does it work:-  Yep never failed for me and that includes extreme use on a Cessna aircraft engine and pushing the rusted head off an ancient Fordson Major tractor.

Rope is also good for locking engines so flywheel nuts can be undone on other engines eg Briggs and Stratton ( don't laugh ).
