I have finnished a two year rebuild and am having some tunning problems. I have a l20b
it has flat top pistons and that is about it. I have a 2lt head It has been ported and
polished with bigger valves. It has a decent cut cam which I have used in other
engines and a set of 48 mm webbers. The problem is it will only run well at about 25
deg before top dead center.Any less and it just starts to missfire. I have had the
colour tune on it and the carbies are woring fine. I have double checked everything. I
just thought it was strange to be so retarded. At this setting it does crack and go
real well. Does anyone have any ideas as to why this is running like this and is this
alright or not. The only thing that is different form my last engine set up is the
head and carbies. before I had a a87 head which was much higher compresion. Would this
have anything to do with it? Any advice would be greatly appreciated as I am going
nuts and am getting quite angry with it.
Simon
