There is no difference in any of the Mach 1 700 cylinders- there is no #1 cylinder. They will interchange in all positions.

Premix the fuel with oil as well for the first tank or 2.

You need to replace that plastic cover. Someone reefed it down too hard and stripped it.

I got that part from my local dealer. Don't remember how much it cost me, but it wasn't too bad I don't think. I've listed the part number below. I'm pretty sure that's what you're looking for.

P.N. 420 2532 57 Exhaust Valve Piston
