Use a carb with an 11mm venturi. The Zama carbs fit the Super Tiger .90 conversion a bit better than the Walbros because they are a bit smaller physically, but a Walbro will fit. You might have to grind down one of the regulator cover screws. The regulator cover should go towards the engine, not towards the prop.

Is there any bad if I use a 12,7mm zama carb?
I've found one for 10 bucks.
Thanks
