Harbor Freight Greyhound Engine

[billranch99]

I own a small engine repair business and also build adult sized go karts. I have put nothing but the clone engines on them and have had great success with them. All parts are readily available and reasonably priced.

I am an approved USA dealer for Azusa Engineering parts, Bullet Lines torque converters, and Lifan Engines (another Honda Clone). I went to the clone engines because the costs of Briggs and Honda engines is so outrageously high! Interested in clone engines but not sure about them? Go ahead, get one. You will be pleased with it!

One post wonder doesn't like the engine... so what? We've got a guy posting on here that's building freakin' racing engines out of these... so I'm thinking, who do I listen to:

1)the guy who's on here and posts actual, factual tech infomation or,

2)a one post wonder who posts speculation and nothing more?

Gosh, I'm so confused

Most likely were dealing with one of these..

I bought one, and retrofitted it on a small four wheeler. Worked great.

would love to see a pic of some of the details. i have a 110cc quad and was thinking about putting one of these HF engines in it.

thanks

Well, since you asked, it was what i considered a 50cc chassis but originally was equipped with a 110cc from china. Long story short, the oil pump locked up on the little 110cc but I thought the kids would enjoy it if I could get it back running. So I bought the 6.5 hp for $99 from HF. Stripped the entire chassis of plastics, wiring, and drivetrain. Welded a sheet metal plate to the lower frame bars with corresponding holes to mount the motor base down to, being careful to line up the engine's output with the rear drive sprocket. I used a go-cart clutch for it. I removed the fuel tank and muffler from the engine so it would fit in the frame. I plumbed a fuel line from the original wheeler's tank to the new engine. I ended up having to slightly angle the box style muffler to fit in the frame. Cut the pipe, added a small curved section and re-welded it. In retrospect, I coulda plumbed it to the original chassis muffler too but I had grown somewhat impatient at that time. String the chain up and trim the plastics just a tad and she was off an running. Motor cranked first pull every time. I found though that the chassis's gear reduction is not near sufficient for this engine combo. The reason is because the original motor/trans had a gear reduction inside of it, as well as the chassis sprocket's gear reduction. So, I burned up a clutch almost immediately. The way the chassis was set up with a 37 tooth sprocket, it was giving me no take off and 60+mph once going. It was a very scary ride. I changed to a slightly smaller front sprocket and a 60 tooth rear and it became very driveable. Mid-range power/torque on the little 6.5 is awesome. Was bored with it at that point so I sold it to a buddy for $125 and he fools around the yard with it after he has had a few beers from time to time.

I replaced the motor on a wood chipper with one of the 6.5 HF motors and I have been highly satisfied. The HF "greyhound" starts every time and operates the chipper better then the OG (B&S) motor did.

How would you go about getting any parts thought for an engine like that? Even simple stuff like a carb rebuild kit.

Used Tecumseh and Briggs engines are easy enough to find and cheap, so I'll stick with them.

At that price, there is only one part to replace. Just get a new one!

I have a greyhound 6.5 hp engine and the cerbital clutch went out er whatever its called..its the clutch thats on the end of the gear shaft n im wondering how i would get ahold of one i have the 66014 engine

I HAVE THE 13HP version on a wood splitter. it has to have 400 hours on it, and i have done nothing but change the oil. starts extremely well in the bitter cold, and is incredibly fuel efficient if anyone even cares. everyone i split with makes fun of it, but at the same time is impressed with the apparant quality and dependability.

i also have the 6.5hp version still in its origiinal box, awaiting some future project

I have a question.

I have one of the Harbor Freight Engines that is labeled as a Central Machinery 6.5 H.P. on a go cart. I made some modifications to it to make it work with the throttle pedal and it works well. Hauls my fat A _ _ no problem.

The problem I am having is when you take a turn too sharp, the engine stalls. I suspect it is caused by the Automatic Compression release opening up and losing compression. Any suggestions on the most effective way to turn the auto compression release in to a manual or any other ideas as to the cause of the stalling?

My step dad built a go kart for me from scratch and put this engine on it. I had the same sharp turn problem as you. We tried a ton of different things before we found that the low oil cut off sensor was setting off because the oil would slosh even when filled all the way up. I am so happy I can turn and properly drive my go kart again. Hope this helps you. Just find the little black box that is near the cut off switch on the 6.5 hp version that has wires going in and out of it and open it up. I think my step dad just popes it open with a blade. It does close back up! And there is a green wire. Disconnect it. You have solved your problem. If your problem continues just private message me or reply to this I'd be happy to help. All input and info comes from my step dad. Now the green wire thing I will check on to double check it acctually is that wire. If I can post a picture I will. I can't check now because it is night time by me. I will have it all final for you tomorrow around 5 pm my time. It's 12:18am my time now. So again just reply or private message me with any questions.
