[Healeys] Sequence for setting BN1 valve rockers

[Bob Spidell]

Firing order is 1,3,4,2; you can set both valves for each cylinder in that order if you're sure the tappets are off the lobe (both valves closed). This will require 180deg of crank turn for each cylinder (requires two full turns of crank) 

Or, use the 'rule of 9:' if valve# 1 is at rock--i.e. valve is wide open--subtract 1 from 9 and set clearance on #8 valve, when valve# 2 is at rock set valve# 7, ... (requires two full turns of crank). 

Both ways work fine, I think rule of 9 is a little easier to be sure valve you're setting is completely closed.

Hi listers 

can anyone help with the short cut valve adjusting sequence for the four 
cylinder Healey so that you don't have to hand turn the engine lots of 
times to set the tappets? A mate gave me the sequence for the six which 
I found very helpful in setting the tappets on my BJ8, I think it's 
related to the firing order but I'm not smart enough to work it out 

thanks
