Varitronic 180ss

Hi , i bought a varitronic for my ss180 no batt ,a month ago.

good spark , for the first 2 weeks, it was starting properly with a cold or hot engine . And now it start first kick only when the engine is cold .

when the engine is hot , it won't kick start , only by pushing it in 2nd gear , but the engine takes 3 or 4 seconds to go up in reeve sometimes it does it ok !

i have lights and horn, could it be a CDI unit issue or other ? 

Thank's sharlly .

The Problem is not your Ignition, i think the problem ist your carb
