So I broke down and decided to replace the CDI and Coil. Spark plug also while I was at it.
I went for a package deal on the CDI and Coil and got the orange performance ones.
First off I had real doubts as to the 'Performance parts' but after an adjustment to the carb I have to admit these part really make a big difference.
The Idle is smoother and the new timing curve really is a pick me up.
The parts I used are listed below.
CDI and Coil
Spark Plug set to .22ths
All in all it is worth the money.
