Hello could someone please help clarify a point for me please ? I have a stationary engine petrol paraffin & I have been told to have the exhaust lever in i.e. open from valve to exhaust for start up & out for running i.e. closed so the exhaust gases travel around the head. I would have thought it should be travel round head for warm up & direct up exhaust when warm & working, any help would be appreciated.
Regards
Rob
