hi mate was me that posted the guide
4 hours yeah a bit much but was a hot day, beer was flowing

and was taking pics notes etc,
if i was to do it again 2 hours tops , straight forward , basically unbolt pierburg, fit weber ,feed choke through, you have to bypass the two hoses by either joining them or removing one and feeding the one remaining into where you removed one
if you have fitted a cam , weber piece of cake
mines is an ex engine and difference is very noticeable
good luck give it a go, sound lke you want to learn, so why not give it a go
