No spark to plug

[Paul shockie]

Hi..I have a chainsaw that won't fire up.so I have taken it apart somewhat. removed the spark plug with ht lead still attached and put it on the head of the engine and pulled the cord to see no spark at all...so I did it again with the spark plug out and just held the ht lead to the head and did the pull cord and a big strong spark happened..I don't get it..is it the plug thats failed...thanks all

They are a " consumable "  and fail from time to time . No biggie 👍 .

I bought 3 BPMR7A plugs the other day just for such occasions, under £5 for all three well worth keeping a few spares in.

3 spare plugs for one saw sounds a bit excessive. 3 spare plugs for your collection of saws doesnt sound enough 😆
