Lost compression - after head change
#24
Hi Bob, Well I have just fitted an HC head this morning, using the same NGK plugs as yourself. I decided to use the starter for first run and to my surprise it span over but didn't fire. Battery not at its best and started to slow up so stopped. It would have certainly started with the LC head. I put a charger on and cranked it by hand (I normally hand start) and a couple of swings it was away and running fine so maybe head/plug combination it does need a decent spark. 
Where are you located Bob?
Thanks
Dave
