Having a little trouble understanding where top dead center is.
"Insert a straw into the spark plug hole and find TDC. The straw will be at it's highest point and there should be play in both "
According to the illustration, the compression phase is when the piston is at it's highest position, or closest to the valves.
But "straw will be at it's highest point" so shortest? Least amount fitting into the spark plug hole? Yes?
Marking my straw at both points when the valves are both closed, "highest" might mean deepest in or highest mark I make on the straw.
As I'm typing this I think I'm answering myself here.... Pretty sure I had it backwards. Gonna try again.
Stuck the gauges in at both points though and there is TONS of space.... probably way too much so you guys might be dead on with the valve adjustment.
