well folks a tied up the briggs rep and made him fess up on the sno engines.
there are 3 real horsepower ranges.
the small one is fron 6 to 8.5 horse...actually 8 horse i beleive not positive on this
the 9 to 12 horse units ...actually 12 horse
last is 13 horse and it is closer to 14 horse
and almost all of them are cast iron bore.
the snappers are all cast iron bore according to the tech.
thare have been no service manuals on the inteck engines since april of 2002,and there is no info on them that is any newer than that.
this is why there is so much controversey on it.
briggs never thought that they would have the success with the engine that they did,things just worked out real well for them.
they plan to get the numbers RIGHT for next season...and you guessed it ...it will be cubic inches not horsepower.
