Hi!
I just bought a free air drifter but it doesn't have a carb or ignition coil. I wonder what size the carb has, is it 28mm or 32mm? and how should it be jetted? As far as i know the ignition system only has a coil and no cdi, but what coil is right for these sleds? Would the coil fitting the models listed below work?

Astro 340/440 SS 77
Drifter 340 79
Inviter 340 78
Best regards Gustaf
