I would like to know if anyone has any photos of how a throttle is set up on a Honda GC 160. Tried to post this question before on 11-20 and it didn't work. Thanks, Owen

I have searched this topic, but didn't find anything clear how to do it, just some discussion it can be done, hook throttle cable to manual throttle control, etc. I would like to see some pics too.

When I did mine I couldnt find anything on the subject. What I ended up doing was fabricating a little bracket that bolts on the block in an existing hole behind the flywheel cover. The cable goes through that over to a small extension I welded onto the top of the governor lever. It attaches with a clevis. then I made a small linkage from the governor to the throttle blade out of clothes hanger wire. Sorry, I dont have pics of it yet, I will try to take a pic and post it in a little bit if you want to see it. Works very well. Here is the link to the bike it is on.

Thanks redairrdstr for your post.

Best I can tell from looking at this engine at NorthernTool and reading a few descriptions like redairrdstr posted: you have to run your throttle cable to the manual throttle control lever. Then you will need to attach a spring to the manual throttle control lever to close it when you untwist the handle throttle at the handlebars. You may want to leave the governor intact.

Not sure what you do, if your GC160 engine has a fixed throttle, but have read you can rig up a throttle linkage for that too. :shrug:

If this engine was more popular for minibikes, I guess someone would have a nice bolt on throttle control for sale. :thumbsup:

Hello cjtmini, thanks for pics, looks good. :thumbsup:

I guess your engine didn't have the manual throttle? :shrug:

I like this engine, may buy one, but exhaust coming out the front bothers me a little. Wouldn't put a pipe on it, plan to run it stock, nice and quite for my neighborhood. :smile:

my engine had the "stationary" throttle like for a snowblower........3600 rpm's all the time. I removed the throttle linkage and governor components inside the engine and fabricated the throttle linkage

Hello cjtmini, did you ride your GC160 much with the stock muffler? Wondering if the exhaust coming off the front of the engine was a problem? :shrug:

More information: I am still looking at GC160's and learned today that model QHA1 has a remote throttle setup, appears it would work well with minibike/ go-kart (QHA has manual throttle, QHAF has fixed throttle). :thumbsup:

finally got my GC160 on the DirtBug and running. Here are some pics of my throttle linkage:

I used flat stock weldable steel 1/8"x3/4" approx 6" long to make the bracket to mount the throttle cable. I bent it in a vise w/ hammer and crescent wrench then drilled 1/4" holes for mounting. I bolted it to the Honda throttle linkage using existing holes. I didn't modify the Honda linkage except I drilled a small hole in the manual throttle arm to attach the throttle cable clevis. I used 3/16 nylon tubing for the cable housing. I attached the throttle return spring to the bottom frame rail with safety wire. I left the governor intact initially, but overrode it with a solid linkage because of throttle control issues (engine backfires when the governor closes the throttle).

I am pretty pleased with my GC160, doesn't seem as insane as the 6.5 clone I had on before (6.5 clone is very cool, but too much for me with my limited experience). :thumbsup:

Nice job chazdaddy. I've been trying to come up with an acceptable method to throttle control for my project. Hopefully my solution will turn out as well as yours did.
