Hey guys, if you're driving around in a Rotaxe-Card engine, the Deloardo 34mm carb is massive. It's a slide carb for those that don't know, that means the slide moves up and down when you put your foot on the gas and actually the hole inside the carburetor is relatively huge for a 1-2-5 engine. So if you do drive around on part throttle, it's not going to hurt your performance, it's not going to hurt your lat times and it may even improve your carburetion at certain points on the track. You do practice progressive throttle, especially coming out of the really slow corners with the Rotaxe engine.
