Bad Villiers Coil?

Post by seagull101 »

Hello everyone,
Went out to test a short shaft century 100 today but found out it had no spark.
I swapped the plug for a good one.
Swapped the HT lead and cap for a good one.
Cleaned and adjusted the points.

Still nothing.

Checked the coil with a multimeter using instructions for the main site and the meter gave completely no reaction.

I'm sure I read somewhere that spinning the motor with a drill will help, But the question is will it help in my case??

Most will say no I'd say yes give it a go as a last resort can't make it any worse just remember the golden rules

Remove plug
remove prop
Oil down the bore

and give it a good old spin I'd be ssquirting oil at regular intervals
Good luck
Roll me up and smoke me when I die
Regret is just a memory written on my brow

Most probably not, with no reading from the coil, I would look for another coil.
As far as I see it, there are only four reasons for using a drill.
One, you didn't clean the points properly in the first place, but now it works, because spinning with a drill has cleaned the points.
Second, the coil is pretty much duff, but if you use a drill and spin it fast enough it will work.
Third, you are too lazy to use a pull cord.
Fourth, now you have used option One and two, you wish you had used option three, as now you cannot remove the flywheel and are out of options.
As you may be able to tell, I have never used a drill to start any motor.
