Check the compression, and for fire at the spark plugs. Also, ensure that the fuel is fresh and free of water or other contaminates. As long as your compression is around 100 psi, or higher, and no more than 15 psi difference between the highest and lowest cylinder reading, there is sufficient compression for operation.
