I have just had my head gasflowed and new rocker arms fitted but have no idea how to adjust gaps i know the rule of 9 etc but where do i start as no valves are down and all ajustment screews are wound right out. really hoping someone can help dont want to miss the fun in the snow.

Right simple . you know rule of 9, so hold no. 8 onto push rod tell its up (valve would be open ) set 1 and so on

wind screws down a bit then turn engiune till one valve just reaches fully open (push rod at its highest ,if you go past keep turning engine till next valve is just fully open ,which ever valve is fully open adjust its number from 9 ie 1 fully down adjust 8 ,2 adjust 7 ,3 adjust 6 ,4 adjust 5 ,5 adjust 4 ,6 adjust 3 ,7 adjust 2 ,8 adjust 1,adjust gap using 8 thou feeler guage ,mark each rocker as you adjust them ,when done check all adjuster screws have roughly the same number of threads above lock nut if not check push rod seated correctly or valve cap etc

so to clarify. Open = spring compressed ?? then set rocker 8 so it is touching top of valve and puch rod then turn engine so value is all the way down/open then adjust clearance of valve 1. how do i know that 8 should be open ?? sure i a missing somthing simple hear

you are right you are missing somthing simple. if you dont get it you are poss to tired so re read in morning , if still dont get it get somone to do it for you

open equals spring compressed ,valves dont open in numerical order you have to watch them start to move moving and mark thge other after setting

thanks james, so i just pick any valve and start there and go with rule of 9

exactly just watch for any going down and stop when just fully open ,if you go past that point keep going till another starts to go down

excellent thank you so much james

ok so put it all back together though i had done a good job. went for a test run and all good to start with and now sounding like a machine gun and running very lumpy. any ideas. water is not bubbling no sign of any leak im not sure what to do
