There are lots of 1/8 scale Ready-To-Run vehicles out there — but their stock engines are too large for ROAR-sanctioned racing events. That's where the 21VG (P) w/21F Slide Carb comes in! With its excellent mid-range power, the 21VG (P) w/21F Slide Carb appeals to beginners, indoor tracks, loose, dusty outdoor layouts: anywhere where top-end speeds are neither wanted nor needed. It's an ideal retro-fit for 1/8 scale RTR buggies, trucks — even 1/8 scale pan cars — and a direct replacement for Ready-To-Run big block engines!
