I recently purchased a good used Mikuni Carb on Ebay. It is a 34 mm carb but how do I know what I have. They said it had been on the shelf and was pulled from an 850 Commando?? It is in good condition.The flat square area on the side of the carb just says Z 4?? and printed close to the choke piston on the body is 1W2 with 00 under it?? I think I have the right carb. The needle jet has 159 P-4 printed on it, Main jet has 250 printed on it and the needle says 6DP5 with the clip in the third notch down from the top. The pilot jet is 35. Are these the right jets and needle for a Mikuni fitted for a 74 850 Commando??? I would appreciate any advise and as usual thanks very much for any help.
