carlsbarn2 7 #1 Posted November 18, 2011 My C-175-8 needs to slow down a little.Its a 1983-84 Black hood so what pulley do I need ? My 1987 310-8 speed is just right. Share this post Link to post Share on other sites
Kelly 1,029 #2 Posted November 18, 2011 They should have the same size pulleys, the engine drive pulley should be a 4" the trans is a 6" or there abouts, do they both have the same size rear tires? a taller tire will make it faster. Share this post Link to post Share on other sites

Kelly 1,029 #4 Posted November 18, 2011 Just because the numbers on the tire are the same does not meen they are the same, best way to check is wrap a tape measure around the middle of the tire, the bigger tire will be faster, also is the engine speed the same?

Rooster 191 #6 Posted November 18, 2011 I have no way to check engine speed but I will check tires Thank you Most small engine shops have tachs, they should not charge you much if at all to tell you what it is running. Share this post Link to post Share on other sites
