Here we go,follow me for a laugh or just shake your head. PO told me the carbs were rebuilt. I took off the top carb and it was clean as a whistle inside. At this point the engine was running on the top cylinder only although there was spark to both plugs. I did not remove the bottom carb figuring there was another issue as both carbs had been rebuilt. I assembled the top carb and put it back in place. The motor ran worse, now it was running on the bottom cylinder only. Again spark to both cylinders. WTF. Must be a bad spark or timing or power pack or sheared key or who knows. Coming to wits end I again removed the top carb and the bottom carb this time. The bottom carb had a bunch of something inside. I cleaned it , made sure air and cleaner flowed through all of the orifices on both carbs. I then reinstalled both carbs and stated it up. Again running on only one cylinder, this time only running on the bottom cylinder, spark was good to both cylinders. Depressing, this did not make sense. Had to be the power pack or key or who knows what. Did some electrical test from an older manual . Test showed bad sensor . I come to find this motor does not have a sensor coil as such. Figured I had to miss something so off came the carbs again. First round bottom carb was full of gunk, I did not disassemble thinking the PO did as the top carb was so clean. Second round cleaned and disassembled both carbs and reinstalled. Third time after two frustrating days I realized it was the cover gasket on the top carb had been installed wrong probably by me the first time I disassembled it.. Well it runs fine now and did not cost anything but grey hair.
Now on to the VRO alarm intermittant beep
Thank you all for your input.
