ahh ok theres three slots on bottom cog 0 a and r ..then theres that again on outside of cog?

 

[delcowizzid]

if cog on 0 on the keyway use 0 on outer edge to line up with chain link. if on A keyway use A on chain

 

[micky vn man]

ok done that so now do i just spin cam until it matches hole on top cog and spin crank until matches the 0 keyway?

Turn engine to number 1 TDC, put crank gear on crank at 0, put the gold link of the chain in line with the 0 mark on the outside of the gear, line the other gold link up with dot on cam gear and bolt it on to the cam. Job done.

Or, if all else fails, read the instructions...

A is to advance the cam, 0 is standard timing, R is retard the cam timing.
You should only have to play with advancing and retarding the cam timing if you've bought the wrong cam for your engine.
Best to match 0 degree to 0 degree with your 9 links (7 inbetween coloured or marked links) to the position on your gregory's manual, i'd describe the rough locations but it's best you look at the picture in a manual to see where to position the cam and crank markers.
