I recently bought a used Yamaha 115 motor 1988 model. Previous owner states that motor was stored for years without running but has very low hours. Has carb kits installed by a professional. The motor starts sometime and doesn't start sometime. Compression is 120 on all cylinders and fuel is new. After first initial start it will start instantly until the next time out and then it's anybody's guess. When it won't start it has no spark to the plugs. What is going on? Thanks, Jeff

You will have to test the ignition system while the problem is there to see what the problem is , if there is no spark at plugs,
no magic answers
