The carburators are mercruiser set up for MCM575. Model 4500
Holley Part no 8082
Main jets .092
Secondary jets .092
I dont know if it has intermediate circuits, how can I find out?
Valves adjusted ok.
No Crossfire.
Valves look ok, not sticking what I can see.
I will test more tomorrow and if problem remains I will change carbs and see if the problem is on the engine or the carb. Today I lean towards lean mixture.
Thanks!

It was an electrical problem in the mercruiser contact between engine and the instrumentation, á bit more gap on the pins did the work.
Thanks for your help!!
