You need to change out the non resistor spark plug.
Most model engines had the NGK BPMR7F spark plug which is a taper seat spark plug much smaller than the one you have.
The tapered seat spark plug works perfectly in the hole originally made for a gasketed spark plug.
Thanks, i need all info i can get ....
