Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hi, my name is***** will be assisting you.
You mentioned that you put a new coil on. Did you replace just one or both? What happens if you leave the small ground wire disconnected from the coil?
You have indicated that it is a v twin, the v twin will have two coils one feeding each cylinder.
If looking at the coil where is the ground wire located as you have the coil mounted? Is it to the bottom?
Okay, this is a twin cylinder but is not the v twin.
Make sure that you have the ground spade terminal to the bottom of the coil when it is mounted. If the coil is mounted upside down it will not work.
Leave the ground wire unhooked from the spade terminal on the coil and see if it will fire of spark then. If it does then the coil is fine there is a short in the wiring or it is grounded out somewhere backwards in the wiring that is keeping the coil from firing.
I have seen several of these new coils be bad right out of the box. It is possible that you have a bad one.
Just make sure that it is mounted correctly(not upside down), eliminate the wiring as a possible problem by leaving it unhooked and checking for spark.
If it is mounted correctly and still won't fire or spark with the ground wire unhooked then you have a bad coil and would need to have it exchanged.
Is it still firing to the plug? Can you pull the choke out a little and keep it running?
70 psi is a little low, it could cause it to die. I would be checking valves clearances.
Intake should be .006 inches and exhaust should be .010 inches with the engine cold.
No problem, just let me know what you find.
That is fine, just come back here and continue our conversation. Have a great day.
Just let me know if you still need further assistance.
