hirth engine wont spark

[bauldrick]

hi every body and happy christmas

early this year i got hold of a hov pod , nice thing in need of tlc
ran well around a small field and then had no time so abounded it untill now

when i came back the dam thing its lost its spark

its a hirth 2704 ra

disconnect the kill side , think it is earth to stop , its a stand alone cdi from the genny windings ,

coil resistance checks out

am a bit stuck :::;

any one with any ideas please

if you have on of these engines can i send you my cdi unit and try it on yours so i can eliminate that part from my equation

anything would be helpful

or any one with parts , also would like a pull start for it as mine is mangled in side


thanks again

david
