Here are some more pictures and pictures of the carby, the other carby picture is a complete unit that came with a few spares when I picked up some mowers a while back, which model carby is this one ?. The problem with the lack of throttle control was the nut directly above the bowl primer holding the linkages in place was slightly loose allowing everything to tilt when throttle is applied so it would not return to idle, I relocated the linkages, tightened the nut and the throttle control is now much better. Some adjustments of the Governor spring have been made in the past by the look of it and am not sure which hole it should be located in. What wasn't evident until I gave it a wash this morning is that there is a fuel drain hole in the base below the fuel bowl. The other 2 mayfair looking mowers i have both have the box type mufflers with the outlet via the slot in the left side of the base. The interesting thing about the base slot in this mower is that it is in the centre rear of the base and the left side of it is higher than the right so when looking at it on an angle as per picture 4 in the above post you can see clearly through it. For want of a better description it resembles a horizontal letter box opening. You couldn't place anything in it vertically unless it was curved at the end. The slot is at least, by my estimation 90 to 100 mm in length. A couple of other things with this mower is that you cannot remove the end from the air filter housing and on the rear flap there is riveted a spring steel plate i presume to give some tension to keep the catcher in place when installed. The other 2 mowers have the spring system.
