bell 11 #1 Posted September 26, 2008 Well, I spent the better part of the past 2 days installing the hh120 in the 633. I had no problem doing this, as I was assured it was a "good engine". I made a mounting system to mount the WH starter/ generator... Then I pulled the engine and re-drilled the mounting bolt holes... They were a little off. (the p.o. mounted the engine) Then I spent a couple hours wiring it, hooking up the throttle/ choke cables, fitting the drivebelt, etc... It started right up... and started smoking (oil smoke) I thought it would probably come out of it... as it has been sitting for a long time. Well, it didn't. I also noticed a strange rattling sound coming from the crankcase... it is not a steady rattle, and it comes and goes as you change RPM. Also, as with all of these tecumseh engines that I run across, the throttle shaft is extremely worn and it WILL NOT hold a tune... You get it tuned in and running just right and then move the throttle and you're back at square 1. I am amazed at how well it fits though... the drive belt cover even bolts up in the proper place with NO DRILLING... I haven't decided what I'm gonna do with it.... I will either rebuild the HH120 ($$$$$$$$$$, if I can find parts), Find a Kohler (8hp most likely), Buy a new Honda engine for it (would probably cost the same as rebuilding the hh120, or put a carrol stream diesel in it.... I am leaning towards the Kohler right now... If I have to rebuild an engine, I would rather rebuild a Kohler. Share this post Link to post Share on other sites
JimD 3,345 #2 Posted September 26, 2008 that's a nice, solid tractor, i would agree with you about the kohler. best dang engine there is, imo. what more can you tell about the carroll stream diesel? i've really thought i would like a diesel in one of my built like a tank horses. would it be easy, expensive, a lot of fab involved? good luck with your project, jim.

bell 11 #3 Posted September 26, 2008 Well, as far as I can tell, the diesel would be a easy swap... The only problem is that the one I want is about $500 shipped. I could build one HECK of a Kohler with $500..... My only concern (other than the $) with the diesel... it is made in China. Therefore, it would be hard(er) to get parts for.

saguaro 0 #7 Posted September 27, 2008 Question about the diesel. Does it operate at the same RPM? Share this post Link to post Share on other sites
bell 11 #8 Posted September 27, 2008 Question about the diesel. Does it operate at the same RPM? Yes, I believe it is 3600 rpm.... I'll post a link in a bit. Share this post Link to post Share on other sites
saguaro 0 #9 Posted September 27, 2008 cool. Been thinking about going with a newer engine myself. That big engine did look good. Share this post Link to post Share on other sites
bell 11 #10 Posted September 27, 2008 Here's what I was looking at... But, with electric start. http://cgi.ebay.com/NEW-6HP-DIESEL-START-E...1742.m153.l1262 I think I am pretty set on rebuilding a kohler though.... I would like to do a diesel re-power on one someday though... :banghead: Share this post Link to post Share on other sites
saguaro 0 #11 Posted September 27, 2008 It would sound good with diesel chug, torqe and tongevity. Thanks for the link. Share this post Link to post Share on other sites
