Hank G.'s question about dating his 143302 engine prompted several incorrect responses. ....It is sad to see mis-information posted for others to rely on.
Trying to research some info for Hank (and myself), I came up with a question for which I have never seen an answer in B&S info.
Now, ALL B&S Model 14xxxx engines were 14 cubic inches. ....ALL had 2.75" bore x 2.375" stroke.
There were 140xxx, 141xxx, 142xxx, 143xxx, 144xxx, 145xxx, 146xxx, and 147xxx model engines.
B&S has always stated that the first digit after the displacement in the model number, indicated the "Basic Design Series." ....These numbers ranged from 0 to 9. ....Reference was also made that this number related "to cylinder construction, ignition, or other major differences."
Does anyone know what these differences are among the models listed above?
We were a B&S dealer for over 35 years, yet I have never seen any printed info which explained what the differences were in the various "Basic Design Series" numbers for any of the B&S engines.
We know that the 2nd digit after the displacement indicated Horizontal or Vertical crankshaft, and the type of carburetor. ....Numbers ranged from 0 to 9. ....Numbers 0, 1, 2, 3, & 4 had horizontal crankshafts, while numbers 5, 6, 7, 8, & 9 had vertical crankshafts.
Thanks for any insight offered. ....I'm here to learn!
