do you mean timing your valve

do you mean timing your valves or ignition?? and dont you mean 0.040 over 0.004 is barely anything the end gap on a set of rings is more than that lol but thats ok. if its youre valves there should be marks on the sprockets and you just line them suckers up and put the chain on and away you go if its ignition there should be marks on the stator plate and you line the mark up with one on the crank case or sumwhere else then make sure you dont move it when you tightening the screws

if the top end was really rea

if the top end was really really bad before you changed it it could be the air screw. but only if u adjusted it before you rebuilt. but i guess it could still be but thats what i would guess next.
