'Laser' Ignition Spark Tester
Posted: Sun Jul 12, 2015 1:31 pm
I'm trying to diagnose rather disappointing engine performance from my Plus 2. Pretty much most things on the engine have been recently refurbed. It has electronic ignition and currently using Accuspark 8mm leads.
Before I go down the rolling road/weber tune expense, I'd like to be sure that everything else is up to scratch first.
I fitted Ignition Spark Testers (bought from Halfords) and it's very noticeable that plugs one and three have bright flashes in the testers. Plugs two and four are far less bright. This always happens even after I've shuffled the testers between plugs. So it's not the testers causing this effect.
My question: Might this be significant, or is the existence of a spark simply binary? (ie, it's either sparking strongly or it isn't sparking at all?) Coincidentally it also seems to be the case that the internal fastening in the lead end caps is less positive a fit on those same cylinders? I suspect the internal clips in the caps may be compromised?
Is it reasonable for me to order the Magnecor leads/cap from Sue Miller etc. or am I simply jumping to conclusions/clutching at straws/wasting my money?
