U GOT IT THE TOP HOLE AIR ONLY. A 1BBL MANIFOLD IS A LITTLE TRICKY TO CONFIGURE BECAUSE OF THE PULSE PORT PLACEMENT AND MOUNTING HOLES AND MY NEED TO ROTATE THE CAB SO THE SHAFT IS VERTICAL. THERE IS ENOUGH BOSS ON THE CARB FLANGE SO I DRILLED ANOTHER HOLE FOR MANIFOLD MOUNTING. I THINK ITS BEST TO GO TO A REMOTE PULSE HOSE. I USE A #28 WALBRO (11.1MM) I DONT KNOW WHAT THE 33CC USES FOR A CARB BUT UNLESS U DO A LOT OF PORT WORK ID BET THAT 11MM IS ENOUGH. IF U GET TO BIG UR LOOKIN FOR RPM TRANSITION TROUBLES. I MADE NEW REED PLATE COVERS TO DO AWAY WITH THE REED VALVES. YOU GUYS SHOULD GO READ THE (ANYONE CONVERTING TORO'S) FORUM, ITS A LITTLE OVERWHELMING WITH ITS SIZE BUT THERE ARE A FEW GUYS THERE THAT KNOW WHATS WORKIN ON THESE TORO'S. I THINK ALL UR QUESTIONS CAN BE ANSWERED OVER THERE. ILL TRY TO ANSWER WHAT I CAN FOR BUT PICS ARE OVER THERE.
