heyy guys, my ke70 is having a few problems. it will start and run fine for the first 5 minutes and then cuts all power and decides to die. does anyone have any i dea what it may be... any help would be greatly appreciated.. thanks in advance...

coil possibly? is it just the engine that cuts out or everything in the car?

the car juss stalls.. but i can't figure it out cos for the first 10 or so minutes the car is running perfectly.

check that its not the wire on the back edge of the dizzy, arking out on the metal coolant line that runs along the side of the Cyl head. If it looks like it is, insulate the pipe with some rubber.

How does it restart?? Instantly on the first turn of the key? Crank for ages then fire?? Leave it to cool a few minutes then first crank??

 

How dies it die?? cough at all, surge then die? Die instantly and not fire again?

 

Electrics often kill it instantly- like a broken wire that moves when the motor moves and loses contact, then when you stop it leans back on the contact.

 

Fuel often dies slowly as it goes lean or rich then gets too much of either.

 

I'd start looking for a broken wire inside the plastic insulation, so while its running wriggle all the low-voltag side of the ignition.

 

Could be capacitor dying, so swap the capacitor next. Then the coil I suppose, so you've covered most the ignition & move onto the fuel.

 

Check fuel level in the carb straight after its died. A blockage might be emptying the carb (we had a leaf inside the fuel tank that would float around and every now & then cover the tank exit pipe... then float off when the car drifted to a halt!) or a bit of dirt in the needle valve might be overfilling the bowl.

 

Good luck!

thanks heaps for the help mate.

Mine did this, check your points :S
