Looked on your website under "Carburetor identification" and did not see years for YF or how to date them. What does the "A" the "3" and the "7" mean on the posters carbs and the "H". I assume the "7" is 1957. is the 3 the third decade? (30's, 40's. 50's) and "A" and "H" the month? I do realize that in business there is proprietary information that takes years to develop and expense and is part of the service provided to paying customers. I respect that and your company and did not wish to disrespect you. I have removed the language from my post. Thanks Carbking.
