shawn844 0 #1 Posted October 11, 2010 I am working on rebuilding my RJ 58, when I bought it it had a Briggs and Stratton 5hp in it. I cant find a K90 or 91 here in utah or I would install one. My question is what is the best replacement engine to install that wont take major retro fitting? Thanks all. Shawn Share this post Link to post Share on other sites
wallfish 16,122 #2 Posted October 11, 2010 I would keep searching for a K90 or K91. Only around $30-40 to have one shipped. I bought a Clinton through the mail and it was $32 to have it shipped. My RJ had a little 4hp Tecumseh on it when it was bought. Just get something small enough to fit under the hood so you don't have to cut it. Place a wanted ad here on RS for a K90/91. I think someone had some for sale not to long ago. That's $.02 worth Share this post Link to post Share on other sites
VinsRJ 721 #3 Posted October 11, 2010 You really have five engine choices, Kohler k90 or k91 / Clinton 1200 or A1200 or B1290. All could be correct for a RJ 58 / 59. Share this post Link to post Share on other sites
wallfish 16,122 #4 Posted October 11, 2010 You really have five engine choises, Kohler k90 or k91 / Clinton 1200 or A1200 or B1290. All could be correct for a RJ 58 / 59. Quite Vin, we don't need another guy out there looking for Clintons Share this post Link to post Share on other sites
shawn844 0 #5 Posted October 11, 2010 Thanks for the info on the engines, I will keep trying for the K90's and the others. There's not to much of those engines out west here in UT. Share this post Link to post Share on other sites
shawn844 0 #6 Posted October 12, 2010 Well I broke down and bought a used Briggs industrial 5hp, its in great shape and fits perfect. I am still keeping my eye open for the K90. Share this post Link to post Share on other sites
