    I have marked this picture with three red circles. The one on the left lost a small plug with a pin hole in it I was lucky enough to find it. However I am not sure if I put it back in it will stay, anyone else ever come across this. I was also curious about the circle on the right that has a brass insert, this is the only carb that has it and this seems odd.

      Reasonably sure it was the '79 model year, but I just can't prove it.
      It was mod to cut down on leaks the '78 models had.

        On closer inspection I do not think that I have the bolt, however my casing does not look like yours. Strange.

          Yours might be a very very early '79, using up the '78 heads and cylinders. Mine looks like a '78 cylinder, and just grabbed a '79 head before it got the bolt hole machined and put it together. Beats me, but I do believe it's original.

            What do you think about rebuilding the stock rear shocks?
            What paint has been used successfully for the carbs? Or does anyone have a better way to make them look more presentable?

                  Any thoughts on the scoring? Also on the previous picture is that paint on the camshaft?

                    What I've done in the past is to clean the bodies with Simple Green and a stiff nylon brush (do not use brass or stainless brushes as they transfer onto the carb body) and then polish the bowls and caps and they can look very presentable.





                    If you want a very high finish you can get them vapour blasted, the only place around here is in Chilliwack BC, you could mail them up here.
                    Cost about $140 to clean a set of 4 carbs.

                      I wonder why more places don't do vapor blasting, or soda blasting? Not enough demand, I guess. I went looking for someone to soda blast my cl350 engine, and could only find one guy, 100 miles away, who does it part-time when he's not busy on the farm.

                        Do it yourself - it's not a bad deal to set up but does take some work.

                          Blasting takes a lot of cfm. I haven't invested in a compressor that big. Yet.

                            Got the top end off. I could not remove the cylinder head, then the whole thing came off barrel's and all. I see some marking on the side of one piston that look like scratches, you can not feel them with your finger. How normal or not is this?

                              Piston looks OK to me, if you have the funds buy new rings and get the cylinders honed, also check the small end wrist pins, I've needed to replace those on mine as they were a bit marked up and I could feel a slight wear mark.

                              The most time consuming task can be cleaning up the old gaskets off the cases, I have a set of old wood chisels, so I sharpened the 1" one up and used it flat and it worked really well.
                              Just needed to re-sharpen it a few times so it stayed very sharp and it would allow me to lift the old gasket off in decent size pieces. pretty finicky work and you need to make sure you don't allow it to dig into the aluminum and damage the surface. Just keep it flat to the surface and it works well.
                              Others have used different strippers with some success but I was concerned about getting the stripper to stay in the garage so my wife wouldn't see her.

                                Thanks for the advice about the wood chisel. I have an old 1 inch chisel. I would love to get new rings and hone the cylinder it makes sense but the engine had good compression so I am struggling with this purchase. I have heard the same thing from others about the stripper
