The carbon ones are cheaper to manufacture, but their resistance values can vary by 20%.
The wire wound ones are more accurate, normally within 5%.
The carbon type age badly and the resistance rises as they get older and coupled with corrosion it plays havoc with the spark, causing misfires, poor starting and all sorts of other issues
Be sure to clean the brass piece deep in the cap also. I usually spray the inside of the cap with WD40 before reassembly
If you put back the original caps with the NGK resistors pack the top of the cap with vaseline before replacing the rubber boot, no more water ingress.
Hi folks next update done all the above inc changing oem resistors for cleaned up ngk ones started it up with a loud pop now i remember i think petrol or somthing was dripping from the joint where the can joins the pipe thats y i turned it off the other day.... anyway as said started sweet as a nut and ran lovely not a chug anywhere went up and down the road sound no chugging so left it to idle n then it started chugg chugg but if i rev it hard theres no chugg....so guys whats the next step b4 stripping the carbs down....really do appreciate your help on this thanks
