Gonna need more information but to start with you need two things.Fuel and spark.First remove the spark plugs and crank the motor, with the body of the plug held to the cylinder head. If you see a spark, that's good. If not, the problem is most likely electrical. Make sure the spark plugs are clean clean clean. Two-stroke motors have a tendency to foul the plugs with carbon due to the nature of these engines burning oil. Clean plugs every year is good soup. The groups site is calling NGK BPR6HS gapped .045" the correct plugs.If you have a good spark, then the problem is a fuel problem. Has the engine been sitting for a while? The fuel can go bad pretty fast sitting around. Pull the fuel line from the fuel pump on the side of the engine and make sure you have fuel getting to the carburetor. Pump the primer on the fuel filter assembly and make sure there is fuel there. Be careful, gasoline vapors are heavier than air and they love to explode. Be sure the blower is running the whole time. A word of warning here, the water pumps in these engines is right under the power head. These engines have been damaged by running them with the boat out of the water. The engines need to be submerged in order for the pump to prime. Water pump parts are becoming scarce so don't let the engine run without cooling water being present or you will create another headache. The boat must be removed from the water to work on the water pump. Please be careful!Dan
