COMES WITH SIZE 72 MAIN JET AND 38 IDLE/PILOT JET INSTALLED

THE ATC70'S 1978 THRU 1985 HAD A #58 MAIN AND #38 IDLE JET STOCK

THE CT70,S 78 AND NEWER FOR THE MOST PART HAD ALSO A #58 MAIN JET

*

bolt pattern center to center approx. 42mm 

*

ALSO SAME DIAMENSIONS AS THE TRX70 CARBS

THIS CARB WILL BOLT UP TO ALL ATC70'S 1978 TO 1985 AND CT70'S 1978 AND NEWER.

THIS CARB HAS THE SAME MEASUREMENTS AS THE STOCK CARBS, BUT THE FUEL VALVE AND CHOKE LEVER IS ON THE RIGHT HAND SIDE. ALSO THE MAIN JET MAY (OR MAY NOT) NEED TO BE SMALLER IF YOU HAVE A STOCK ENGINE.

SEE BELOW FOR NEW SMALLER MAIN JETS OR SIMPLY TAKE THE MAIN JET OUT OF THE CARB YOU HAVE NOW AND IT WILL FIT INTO THIS NEW CARB.

BUT IF YOUR ENGINE IS STOCK YOU MAY NEED TO GET A 58 MAIN JET.

YOU MIGHT WANT TO GET ONE OF THE SOLDER ON CABLE NIPPLES IN CASE YOU HAVE TO SHORTEN THE INNER CABLE SOME,, OR GET OUT # 275N BELOW AND IT SHOULD USE THE STOCK CABLE AS IS !!

MAIN JETS ARE LISTED BELOW FOR THIS CARB,, AND SOME IDLE JETS TOO.

I WOULD ALSO RECOMMEND USING INLINE FUEL FILTERS..
