I checked mine today at .045" so closed them up to .040" middle limit.

Started in less than 1 revolution.

Its almost back together again now.


I put new NGK Iridium plugs in today with .040 gap which is also what NGK say.

Prior to changing it took 10 secs turning, 5 rest, 10 turning, 5 rest then fired after another 7-8 seconds.

With the new plugs it fired immediately.

Before I get too carried away I'll see how it starts first thing tomorrow morning.
