hi. having problems with a intermittent weak spark.set plug lead 6 mm. from cyl. head, great spark, suspect ngk resistor plug cap. put plug only finger tight in head, kicked her over, no spark. can anyone help me, thanks bj.

Elimination process" change cheapest component first,, , do you have a meter " [ohms] and a manual ?

replace the plug and plug cap and try again, not really expensive to do

good morning,thanks blackchat &airhead for replying.got my haynes & multimeter.new points, new ig.coil. new wire from mag.resistance of mag coil ok. removed plug & ngk resistor plug cap . set ig. plug cable 6mm from cylinder, 4 out of 6 sparks only. thanks again. bj.

4 out of 6 eh, try disconnecting the capacitor during the checks?

10/10 ? new capacitor required !

thanks airhead, new capacitor& plug fitted, no joy took cap. out of the circuit, same result, thanks for all your help, b j.

do you have a haynes manual?

"thanks airhead, yes i have an haynes. today put ht lead 6mm from head bolt, great spark. screwed in plug, not connected to ht. lead, not a spark in site????????? any clues greatly appreciated bj."

say that again?...but differently

did you mean screwed in plug cap, fitted plug and rested on cylinder = no spark?

thanks airhead, no plug not connected to ignition coil lead, plug screwed into cyl. head, no spark what so ever thanks bj.
