Mike you where saying you have done a lot of work to this engine over the last month or so....has this overheating only started since you carried out the work or was it there before,
Are your EGTs the same now as before the work also....has the timing been adjusted recently...over advancing it can cause overheating...spark plugs....have they been changed,
Do you have a CHT gauge on this engine....I wonder do you have access to one of those hand held laser temp gauges to verify that the a/c temp gauge is really telling you the truth...there quite cheap these days on ebay.
Nick.
