Hi Andy sorry for Delay ,
To be very Honest My Ld Runs like a dream on the varitronic, pulls better and goes faster, It really does,keeps the power going through the gear range
I am Building a 57 Ld and are putting the varitronic straight in ,
I got mine from
http://www.scooter-center.com/en/classic but the price has dropped in the uk so now are about the same , check out the E bay they have them,
or any of the Lambretta centres , cambridge etc,
Basically it is a very easy conversion all details are included in the kit, You will need a new woodruff key as they always recommend to change,
You Find TDC bolt on the new bits attach wires , the timing is done by turning the stator plate , mine is fully to the right and she Kicks over by 3rd kick and storms along
Hope that helps , some photos are on my FB page David j frost , ? monkies wedding,
All the very best,
D
