Looks ok at first sight. The only bit of damage I could see was the plastic choke lever which got broken in transit. John sells them for less than £3 so no worries there. I made a temporary one from an old credit card using the old one as a template and it works just as well. The other item I attended too was the air intake. Apparently it should have a longer rubber cowl that fits to the rigid air intake on the carb (an amal 416 apparently), but they are no longer available. The previous owner had botched it with a bit of gaffer tape and inner tube but it was about to fall off, so I bridged the gap using a piece of plastic drain tube, a bit of inner tube and a couple of tie wraps. I then went out bought some fuel, some TCW3 oil and topped the tank up with 25:1.
I strapped it to a wheelie bin, then followed the intructions carefully from here and it started first pull. Happy days.

So first impressions are good, it pumped water really well with a pencil thick stream emerging just as described on here. It was cold today only a degree above freezing and it did take a while before I could reduce the revs without it cutting out. When I could, I engaged the clutch and gave it a reasonable run. This thing seems to have a fair bit of grunt! Being as new as I am to this, it is difficult to learn much from running an engine in an oversized bucket, but it did seem that the tick over speed was quite high. When I reduced the throttle it did seem to die, or often when I engaged the clutch on lower revs the same happened. I must admit I was a bit surprised at just how much smoke it produced too, although i think it is accentuated when running in a bin. Maybe this is just a case of getting used to the foibles of this particular motor....
After running for a while I also noticed a little dark oily sludge running down the exhaust tube, is this a worrying sign? I would like to identify any potentially expensive gremlins while I still have a return option on it.
