New starter turns engine but will not fire
For the engine to run, it needs compression, fuel, and spark. having the proper tools for the ob is best but I will go with things readily available, without special tools.
Disconnect a spark plug and put a screw driver in the boot to touch the metal inside, place the shank of the screw driver close to metal, about 1/4 inch and crank the engine and look for a spark.
After cranking the engine, fuel should have got on the spark plug, remove the spark plug and check if it's damp or wet with fuel. Carburated engines are viewable if you operate the throttle and look down the carburator for squirting fuel.
With the spark plug off, stuff a rag on the threads where the spark plug threads into, don't fill the cylinder with the rag, just cover the hole by stuffing a rag on the threaded part, use a screw driver, then crank the engine, the rag should pop out of there during the compression cycle.
Apropiate tools needed is a spark tester, compression tester and fuel pressure tester and noid light. If you have these tools it is prefered you use them.
