Dead Cylinder

[Gun Doc]

I took a little break from the car to get my head right…I have two bikes that I have been neglecting since I got the Cobra. One of the bikes has been sitting since I got transferred to Tennessee a couple of years ago; the other has sat since I got divorced four years ago…So I spent some time on them and got both running. I just now started back on the Cobra.

I did a cold cranking (throttle closed) compression check of the dead cylinder and got just over 150 psi. I have not checked the other cylinders yet, frankly because it is a real pain to get the tester started in the spark plug holes!!

I am not sure how much compression I should have, because of cam, etc, but I am pretty sure 150psi cold with starter motor only should be plenty for that cylinder to fire if it has fuel and spark.

I am now debating whether to pull the carb, or just go out and buy a new cap and rotor. I did look at the cap and rotor and they both look okay…Nothing obvious, like a visible crack, or burn.
