Hey folks, asking if any of you have used the higher stall springs and weights.
My son’s kart is a two seat yard kart. Has live axle, disc brake, 50t sprocket. Engine is a stock predator 420 with knockoff 40 series converter.
The thing runs awesome, but when floored from a stop, the engine lugs down some, then takes off. It’s not a carb issue, just the tc grabbing very low in rpms.
Anyway, I ordered the red springs, and medium rollers for the driver. Being the engine is stock as a rock, should I just install the springs and see how that does first? Or install both? Thanks in advance.
