HEEELP!! Spark Problems..

[robbobnob]

OK I'm stuck now. My RS 125 was not starting and now it is, sort of. I was checking if it had a strong spark so when i checked, it started but when i put the lead properly on the spark plug it died..What the hell could it be?

[Cigaro]

Fecked HT lead?

[robbobnob]

I hope not. I thought that but then it's sparking perfect when it's not sitting on the spark plug proplery. If it's touching the outer rim or about 1mm away its perfect starts first time.

Exactly, which sounds like a faulty contact inside the HT lead. May as well replace it, they don't cost much.

OK, I'll give that a go. Cheers.

Have you tried a new/different spark plug?

After that my next try would be a new plug cap. (I assume it is a lead and cap job not an all in one?!?!).
