Rope length for replacing valve springs.

Beats me why anybody uses rope........
Totally unnecessary....
Too late once the rope gets caught or knotted.....
And you don't need a compressed air either....


Get the piston to TDC. Get an screwdriver & put a 45* bend in it about 1.5" from the end. Put in the spark plug hole & let the tip rest against the valve that is going to have the spring replaced. S'driver handle acts as a counterweight & keeps the valve closed while removing/replacing springs. Often, just the friction of the stem seal keeps the valve in position. If valve drops, seals might need replacing.
