First two digits of the model are the displacement, 40 ci vs 42 ci , but the data shows the 42 as 40.15 ? Maybe they slipped a decimal and added a zero? I suppose the actual c.i. could be calculated from the bore and stroke. But that data shows a VERY small difference in those numbers! Could that small difference amount to 2 c.i. ? No... definitely not. IF the bore and stroke is correct! Looks like there's a mistake there... or somewhere... they list this one: Which makes more sense... Here's the B&S specs on both. The 18HP was a 'stroker' version of the 16HP. The piston is the same. Edited October 7, 2021 by Jeff-C175 1 Share this post Link to post Share on other sites

Am I looking at something wrong ? I must have flipped around the numbers. My fingers don't move as quick as my thoughts do... 2 Share this post Link to post Share on other sites

That would be a nice repower if the Tecumseh cannot be saved. I will look at it even for a backup motor 1 Share this post Link to post Share on other sites
