Thanks Fish. The left one it is apparent is an "S" but the right one looks like mine...could be an "S" and "6" or an "8" so I guess that mine is a n "S" pre-fix.
Been looking on a well known auction site for a gasket set or carb and no joy (in UK) for gasket set so will have to try my dealer. I did see a carb and provide a link to the advert. Mods I am not endorsing the item or the site merely demonstrating the price that carbs (2nd hand) go for over here so I can compare to the price of a gasket / repair set.
As my earlier post my carb has a reference of 577 613A, which now I feel should be " S77 613A " which is odd as the above add states S186 - shame you cant see the makings in the pictures.
Based on this I think I will go down the repair route
Will keep you all posted and again thanks for your input
It should have C1Q stamped in the middle of the carb, not on the side with the S97. I had that carb on my Stihl km55-r and replaced it with C1Q- S186 carb.
