Cater YS M38/M38A1

Post by MASH_4077 » Sat Sep 09, 2017 8:54 am

Is the Carter YS carb the same for the M38 and M38A1? Got a friend who has an M38 with a good W/O carb but wants the correct YS carb installed and has a YS carb. Any answers are appreciated!

Not interchangeable, the YS 950 for the M-38A1 id in line with throttle body mounting studs, the M-38 YS has the elboe at right angles to intake manifold studs. The throttle bodies between the two also do not interchange due to stud spacing and different size throttle body.

Thanks Joel! I'll compare the carb he has to the one on my M38A1 to see if it is the same or different.

Throttle body wear is a major consideration on used YS Carburetors it will affect idle.. Some Dealers have NOS available.
