Tecumseh spark question

#1
I have h50 which is lighted. When I hold spark plug clip by itself to finger no spark When turning motor over. When I hold spark plug clip in hand and touch with finger while resting hand on engine block clip has spark to my finger. Is there a ground problem? Why would this be happening. Note : clip to actual plug no spark. Meaning engine won't fire. Any insight would be great.

Best way to do this is with a known good spark plug attached to the plug wire (leaving the old spark plug in the engine) and ground the threads of the test plug to a good ground on the engine (away from fuel/gas) and pull the starter cord. Be careful not to have fuel vapors around since the spark from the plug testing can ignite the fuel/gas vapors. Bad spark plugs are pretty common.
