jb4249 131 #1 Posted May 5, 2016 I have a nicely restored RJ 58 that I have been working on for a couple of years and finally got it together this spring. I have a K90 for it that jut refuses to run. I did a project over the winter and put a Predator engine from Harbor Freight on a Lawn Ranger, and it worked out pretty well. So I picked up the small 79cc engine and put it on my RJ58. It fit perfectly and runs and the tractor drives nicely. I want my grand kids to be able to use this, as well as my other WH's so I wanted the put the belt guard on. I had a repro that I bought on the internet and found that it fit perfectly. Bolts to the engine and the transmission side plate as designed. No big deal I guess, I just wanted to pass it along. Thanks, ted jb4249 12 Share this post Link to post Share on other sites

AlwaysLookin80 1,308 #4 Posted May 5, 2016 That's awesome it fit correctly. I was thinking of putting a new engine on my daughters suburban. How much did the engine set you back if you don't mind me asking? Share this post Link to post Share on other sites

jsp_333 273 #6 Posted May 5, 2016 You weren't kidding when you said "nicely restored". Looks fantastic. And yes please post more photos. Share this post Link to post Share on other sites
jb4249 131 #7 Posted May 5, 2016 The Engine was $89 at Harbor Freight. It is the 79cc model about 3 hp. I put the 212 cc on my Lawn Ranger. I couldn't find any good pics of the RJ, so I will take a few this afternoon and post them. Ted 3 Share this post Link to post Share on other sites
Achto 28,019 #8 Posted May 5, 2016 (edited) If you check out some of the go kart web pages you can get an exhaust flange and use some conduit to get the exhaust away from your leg. You could also just weld a pipe nipple to the flange and use pipe fittings to extend out from there for a more ( like they did at the factory look). I used a motorcycle muffler on mine, it's a little loud but it fit the theme of my project. My Suburban has the 212 HF engine in it that I have modified to get around 8 1/2 hp out of it. Nice looking job on your RJ! i Edited May 5, 2016 by achto 1 Share this post Link to post Share on other sites
jb4249 131 #9 Posted May 5, 2016 As promised. The Lawn Ranger is in the middle and my 854 is closest to the door. Also pictured is the K90 engine that I intended on using on the RJ, still might if I can get it to run. 7 Share this post Link to post Share on other sites
AlwaysLookin80 1,308 #10 Posted May 6, 2016 Looks great. With people wanting 2- to 300 for the 4 hp kohlers, I think i might go that route on one or two of my tractors. Very nice RJ. Share this post Link to post Share on other sites
WHX?? 49,576 #11 Posted May 6, 2016 Whats going on with the k90?...looks like it's ready to jump off the bench and get working! Share this post Link to post Share on other sites
Lane Ranger 11,051 #12 Posted May 6, 2016 I have a K90 that had no spark and it turned out that a wire to the points had been chewed up by mice behind the bearing plate ! How they got in there I don't know but it took a while to find it and once repaired spark was like a new motor! Share this post Link to post Share on other sites

If you can find a K90 or K91 in good running condition for 2-300 bucks that is a steal these days... If it has a working Fairbanks or Schnacke recoil on it then the recoil alone can fetch 100-150 bucks. Worth the investment IMHO. Nice RJ by the way! Good to see it up and going and that you are enjoying it.. 2 Share this post Link to post Share on other sites
jb4249 131 #14 Posted May 7, 2016 The K90 has a weak spark. I've tried points and condenser and the little between the points and coil. Also the plug wire. I had a parts engine and used the coil out of it and same thing. So it is either the coil or I've set something wrong. I am going to get back after it this summer, but for now I can play with it. Thanks for the comments. Ted Share this post Link to post Share on other sites

jb4249 131 #16 Posted May 7, 2016 Here's a picture of the Raider with Craftsman set. It' just sitting there. I'm also including a picture of the top or the transmission and gear lever. This is supposed to be a 6 speed, so I think there should be 2 levers? I also tried to adjust the forks inside, under the lever. One of them moves and the other does not, so I need to look into this further. I do however have a 702 that has a 3 speed that looks like it would fit. I need to try that or possibly try to fix this one again. Ted Share this post Link to post Share on other sites
