I recall reading ( but cant find now) a thread about rough idle on one of these . My old one has started doing it now ....
I 'think' one of the knowledgable guys said something about an air valve may be the issue...?
But its almost hunting at anything up to 1500 revs , and after thats its sweet. Not a misfire, just a slight surging feeling for a second then fine for 10 secs (ish) then the same again.
Any ideas - anyone find the thread ?
The new owner has a merc engineer but wondering if I point him in the right direction it may be quicker/cheaper for the owner, gain me points so I can keep using it
