If you are only getting spark from one and you know that they both work, then most likely it is the points or condenser. Since you will need to pull the flywheel to change even one, it is recommended that you change both to avoid problems later on.

96zr580efi - you've made 5 posts in this topic and added nothing of value

i agree with the speed, colts were speedy little things

try swapping the coil that isnt sparking with your spare

well last night i got both sides to spark. i changed the condensor on the side wasnt working and it works now. but for some reason the side that worked before doesnt any more. i didnt even touch it?? they both had spark for about 5 pulls then i watched it slowly go away as i pulled more?? did the condensor just go bad on the other one? i dont get it its not the coil or plug. let me know what you think
thanks

When ever you have those apart to change even one condenser, it is wise to do both and the points should be freshened at the same time.

i just put a old one from the other motor on it to see if that was the problem. it must have been. i ordered 2 new condensers off the net im still waiting for them. i just dont get why the one that worked before all of a sudden doesnt any more did the points get dirty in like 5 seconds or did the condensor break in 5 seconds i dont know i hope they both work when i get the condensors for it. cross my fingers

A condenser is a capacitor and they are prone to sudden failure. That's why if one fails it is best to replace both. Did you file the points? If you do, and you do not nave a points file, you can use an emery board to smooth the contacts. Only use two or three strokes and you will not have to reset the gaps.

ok so i had fun today. i put the new points and condensors in and thought i set the point gap good. it has nice spark on both cylinders, consistent. i put everthing back together put some gas in it and it started up and died. did this a few times then i got it to run smooth for about 30 seconds and it backfired. i spiled alittle gas behind the carbs. i srayed some in there to get it to strart right up well when it backfired it lit all that gas on fire man that was scary. so now if anyone can help with some info on setting the points that would be greatly appreciated. thanks
