[Bob Carriere]

I can wread and rite....... and can count one carby, two carby, three carby and anoder one and anodur one......

Seriously.... trying to figure out the various cast iron bases on the multi YF carburators I have...... and using specs on jet size from the manuals.....but for once my books are too old and are good for 1940 WW II era but my 1959 chev 261 used YF models that came later..... so either do the web or dig out more old books...... Had a Carter YF rebuilt but it came back with the small throat...small bolt pattern of the 216 and early 235...... I do have a larger bolt pattern throttle assembly on another carb but not sur if I can swap the parts.......concerned that the jets maybe too small for the cfm sucked by the 261........ will be back to the Toronto Oak brothers in March for look and learn session........

Boob..... never too old to learn...
