Dos my choke feed not come from coil!

No that is the electro-magnet fuel cut-off valve, the choke is purely mechanical and is on the side and can be adjusted you should see 3 marks you can slacken off the screws to adjust generally it is on the middle mark. You can rotate it either way for seasonal changes.

if the carb is the only change then I suspect its the carb. Which carb have you fitted?
