Thanks Flypaper 2;

That kinda answers things. I have a old Stihl 54cc. on a spitfire and it had points, so I got one of those little modules on it, they only weigh a fraction of an ounce. It works great, hand starting is no problem, but....... I also have a Ryobi 26cc. with stock coil, it hand starts no problem, are you saying it is buit into the coil?. There is no place to put the module on the newer coils. I changed the coils on my 42cc. with numerous others, some I believed sparked at low rpms, but it made no difference to that engine.

So is it the coil?. If so is there an id number for the older lower rpm type coils?

Thanks guy's Peter
