I'm still looking for copper cored plug wire. Called all over the Phoenix area and nobody has any. Talked to a couple of small engine mechanics and they both agreed that a magneto engine should use copper cored wire and not carbon resistor wire.
What about replacing the cdi unit all together with a coil from a 50cc 2-stroke dirt bike coil, like Honda,Yamaha,Kawasaki suzuki no white wire doe any one have any knowledge of the idea?I have three motors. I decided to upgrade the spark plug wires because of the cheap, poorly engineered bakelite boot on the ones that come with the kit. One of the plug wires easily unscrewed from the CDI and the new one screwed in. End of problem. The second one was a different story. I tried to unscrew the wire and it would not come loose. I tried pliers and ended up twisting off the wire. Then I tried to dig what was left of the old wire out of the connection to no avail. Apparently they have started gluing the wire in with some kind of glue or something. I guess Mr. Grubee wants to make sure that his low quality parts stay on his low quality motors.
I see you have a Puch cylinder head. Which one do you have on what motor? I have the Hi-Compression head ment for a 50cc mounted on a 66cc. The compression is supposed to be astronomical, 13:1. They have a head made for 70cc and I'm thinking (although not very hard) about getting the 70cc one for less compression.resistive carbon core wires DO WORK
ive been running an 8.5mm msd supercore (carbon) wire for a long time. better than the copper core it came with in terms of throttle response. looks better too, and i had it laying around the garage.
being 8.5mm, its huge and i had to trim it. no big deal
do not run a resistive wire with a resistor plug, so ive heard. i never use resistor plugs though, so i cant confirm this.
Then get one from dragonfly75.So which one should I buy... I dont want one off the bike kit vendors that have the same chinnese one that breaks down i want a high performance ignition coil.
