New Powerspark 65D Re-curving for Red 998 Mini project

Recurving a Powerspark 65D distributor for a 998 High compression mini.
I fully dismantle this unit to get access to the main distributor shaft.
I measure the amount of advance and add modify untill I achieve the advance that I want.
I test and replace the primary and secondary springs to achieve the advance curve that I need for this particular engine.
Then reassemble the unit.
