what is your ignition system like? Are you running new plugs? Did you drop any? What are your leads/dizzy cap like? Do a comp test to eliminate your head

Adjust the tappets..

while its running pull one spark pulg lead at a time if it runs the same then its a lead or spark plug ,

or a manifoild leak to test this spray wd40 over the manifold while running if it runns better theres your problem

or carbie probs

a carby prob wouldnt make a miss, just a rough idle. A air leak may if its MASSIVE but usualy just makes it hunt or high idle.

Mike may be on the money about the tappits!

u guys mite be rite, can u tell me or show me threw pics on how this is done, sorry to sound like a dumb arse,i checked for manifold leaks and it made no difrence,it just runs like ####. thanx for helping lads.

did you take one leed off at a time ?

you would wanna get a workshop manaul for the tappets

yeah bloke, took each lead of made no diffrence,i'll adjust the tappets and let you guys know how i go . cheers for help.

Get a Gregory's or something for more details.

If you don't adjust the valves after installing a head -- it WILL be off tune badly.
