I doubt Dyno facilities are common there. Try to get a carburetor that’s as set up as possible. Maybe pay to have one that’s been dyno tested and set up on a very similar engine to yours shipped over.

Id recommend buying one setup to be a blow through carb from CSU or someone like that. It would be cheap insurance. Your science experiment carburetor could blow up your whole engine. Try to copy a proven engine combination as much as possible

.thank you in advance and excuse my gramar

I run a blow through carb set up and if you don't have access to a dyno at least get a wide band o2 set up it will make adjusting the carb a little less difficult

Watched Engine Masters on TV (cable - motortrend channel) the other night, the episode they tested different blow thru carb hats and different positions of the hats with 8 02 sensors (1 per cylinder) and all i can say is yikes ! Oh, and try go find it on youtube or etc.

Believe episode is ‘ Carb Hats for Blowers ‘
