Bruce,
Thankyou for getting back so promptly.
I would have to say the spark is more blue than yellow. I did get a good zap out of it quite recently and when I tested just now it seemed like a fairly strong spark.
I did a quick compression check as described in the Gregory's Victa Rotary mower manual (1955-1987 - all I could get from the local library) and felt very little resistance, infact it would probably
do a number of revolutions with one swing of the blades, thus my thinking of changing the rings.
Regards,
Jeremy
