Browning Posted March 18, 2013 Report Share Posted March 18, 2013 Picked up this 1976 roto hoe tiller for $20 a couple days ago. Guy wanted $40 but couldn't get it started so he told me give him $20 if I still wanted it. Got it home and it fired on starting fluid and sounds good. Problem is the carb is very gummed up. He just ran fuel out of it instead of using stabil. Besides tearing down and cleaning the carb out with carb/choke cleaner, and changing oil is there anything else I should do? If I can't get it all cleaned out I'll be ordering a carb kit for it. http://i.imgur.com/QCXh0in.jpg Quote Link to comment Share on other sites More sharing options...
JaSSon Posted March 18, 2013 Report Share Posted March 18, 2013 Old small engine carbs are real pains. Theyre junk. Quote Link to comment Share on other sites More sharing options...
Browning Posted March 18, 2013 Author Report Share Posted March 18, 2013 Old small engine carbs are real pains. Theyre junk. I found some new ones online from $80-100 and I guess some are updated and do away with the adjustments and are supposed to be pretty much tinker free. Figured it's worth getting this one cleaned out and seeing how it does before getting a new one. Quote Link to comment Share on other sites More sharing options...

Browning Posted March 18, 2013 Author Report Share Posted March 18, 2013 Harbor Freight horizontal shaft motor? http://www.harborfreight.com/horizontal-engine-gasoline-epa-212cc-ohv-7hp-69730.html this is another option but this motor sounds great when I had it running on starter fluid. So if I can line out the carb it'll be a great $20 tiller lol Quote Link to comment Share on other sites More sharing options...
gillbot Posted March 18, 2013 Report Share Posted March 18, 2013 I had an old tractor that had a gummed up carb. I took it off and sealed it in a bucket of gas for a few days. It worked good enough after but never was "right". A buddy helped me rebuild it properly and it ran like a top after that. Try soaking it sealed in a container of gas for a few days and see if it'll work well enough for ya, otherwise you'll need to completely disassemble and rebuilt it.

jeffro Posted March 18, 2013 Report Share Posted March 18, 2013 Change oil Change spark plug Clean air filter Replace rubber fuel lines if degraded Inspect drive belts for damage or wear. Replace if. Bonus: Tear carb down and clean it. Dont forget to oil/grease up the blades. Quote Link to comment Share on other sites More sharing options...

I did this with one off an mtd mower but used kerosene instead. Worked great. I tore it completely apart though so that probably helped Quote Link to comment Share on other sites More sharing options...

There's a removable plat to access the chain as you can see in the pic/ Would grease that used for ball joints and such be fine? Quote Link to comment Share on other sites More sharing options...
starkmaster03 Posted March 18, 2013 Report Share Posted March 18, 2013 That is the exact same 5hp tecumseh engine that I had on my old mini bike. My dad had it for over 30 years and we never had to do anything except change the oil and spark plug. Quote Link to comment Share on other sites More sharing options...

Haven't had much luck finding locally, you could try calling some bicycle shops. Or order it on Amazon Quote Link to comment Share on other sites More sharing options...

Didn't want to take the chance of ruining one and not being able to get it back together. Quote Link to comment Share on other sites More sharing options...

Didn't want to take the chance of ruining one and not being able to get it back together. I'll take my chances. Found a rebuild kit for $9 shipped on ebay for the carb and some gaskets cheap on another site. Decided to reroute the exhaust so it's not blowing back at me but not sure if I'll wait til later in the year to do it or right away Quote Link to comment Share on other sites More sharing options...
xlr8tn Posted March 19, 2013 Report Share Posted March 19, 2013 check out jackssmallengines.com Excellent site for small engine parts. Depending on the model you can get brand new carbs there for $60-$80. I've used them for a few things and have always been happy with the parts, price, and service.

Akula Posted March 19, 2013 Report Share Posted March 19, 2013 put a little Sea Foam in the carb, itll clean it up. Check to make sure its getting gas from the tank to the carb Quote Link to comment Share on other sites More sharing options...

Browning Posted March 19, 2013 Author Report Share Posted March 19, 2013 Took it apart, cleaned it out. Wasn't as bad as I assumed it would be but the needles were gummed up and rough. Got it back together, made some adjustments and it fired up but the rpm's kept raising up and down. Adjusted it to smooth it out and tried the tines out. All works well but seems like it should dig a little faster. Not sure if it needs adjusted a little more or not. I just messed with the adjustment under the float bowl which I think is for high rpm's. Quote Link to comment Share on other sites More sharing options...

Browning Posted March 20, 2013 Author Report Share Posted March 20, 2013 not sure what qualifies as sharp on these. It cuts just assumed it would rotate faster Quote Link to comment Share on other sites More sharing options...
