Carb tune intake question

<HTML>OK, maybe a stupid question, but I have to be shure.

I changed the original 16mm carb on my Pa-50 for a 21mm, and now I want to improve the air intake for the carb, so more air can get in...

1) Does the carb itself suck the air in, or is the placement of the air intake important?

2) Does anyone have suggestions on how to improve my air intake?

The original air intake is just a rubber tube, divided in three round channels inside the tube. It just points upwards, so maybe if I use a bigger tube, with only 2 large channels, who point towards the front (from where the air is coming) will I get a better performance?

Thxs,

Robin

The carb. itself doesn't suck in the air. Thats done by the engine and generaly speaking the less restriction you have the better the air flow will be. You should also be aware that the mixture of fuel and air going to the engine and the idle of the engine are effected by the air intake, so the carb. will have to be re-adjusted.

Good Luck and Have Fun,

Hakachukai /

<HTML>You might try this... Although I'm not totally sure how well it will work.

Take like, a large plastic soda bottle, and cut the bottom off from it. Remove the cap, and place a hose there. The hose should be large in diameter, and connect the neck of the bottle and the carb intake. Now Hook the bottle to the frame, pointing open end forward.

At idle and low speed, not much should be different.

But when you pick up speed, exra air wll be forced through the carb, and hopfully increase your power somewhat. I haven't tryed it myself yet, but I will soon.

Does anyone think this will work? </HTML>

RE: Carb tune intake question

<HTML> HOPEFULLY IT WILL;

I AM DOING THE SAME THING TO MY 78 PINTO AND HAVE SPENT A LOT OF TIME IN GETTING TO THIS POINT.

WHEN I GOT MY MOP IT HAD 716 ON THE ODOMITER AND WAS ALL ORIG. THAT I COULD TELL. IT TOOK ABOUT AN HOUR TO CLEAN OUT THE CARB. AND IT TOPPED OUT AT ABOUT 24 MPH. I THEN LEARNED HOW TO GET IT DOWN TO ABOUT 5 MIN.

(AND IT ONLY TOOK ABOUT 15 TIMES) TO FINALLY GET ALL THE RUST OUT. THEN I DOMED AND POLISHED THE HEAD AFTER WHICH MY 11 YR. SON, BORE AND POLISHED THE INTAKE. AFTER ASSEM. THE ENG. TOP END HAD JUMPED TO 29 MPH, AND WENT BACK DOWN TO 26-27. AFTER REMEMBERING THE AIR FILTER. AND THAT IS WHAT STARTED THE CHASE AFTER A BETTER AIR DELIVERY SYSTEM, AND TO TRY AND FIND OUT WHAT A BI-TURBO EX. IS. THEN I GUESS I NEED TO LEARN ABOUT THE TRANS. AS ALL IDEAS ABOUT A DERAILER SYSTEM HAVE FAILED!!! I SOULD HAVE SPENT THE TIME AND MONEY ON TIRES, BEFORE RIDING ON WET PAVEMENT. THE TIRES WERE ORIG. AS WAS THE PAINT AND MY PANTS.

ANY IDEAS, INFO, OR SUGGESTIONS. WOULD BE GREAT.

THANKS, AND,
