I have a Have an 05 Honda Rancher 350es. I sat up for a while and would not idle very hard to start. Rebuilt the carb and now it starts fine...idles. ATV loses power as I go up in gears. Pulls well in first...tops out in second. When I shift into third is when I start having trouble. Tops out about 17 or 18 Mph and gets no faster in forth or fifth. It seems like it starts bogging down. Any advice?

Thanks in advance

Kory

This probably should be posted in "Repair & Maintenance", as this page is more related to off topic discussions. this forum is the best to find out "how" to do something.. :smile

welcome to the forums, i moved your thread to the correct place . check to make sure your carb is getting plenty of fuel from the tank ?, it almost sounds as if your running out of fuel ?.

As shade said. I had this experience with my quad, rebuilt carb so many times. Turns out since the petcock was on a slight hill in the tank, I wasn't getting much gas.

Fill up tank and check fuel line, be sure it isn't pinched anywhere. Be sure petcock is on.

Also if you can turn gas flow on (petcock) and open up draining screw at bottom of carb. There will be a continuous flow for like 4 seconds (float bowl full of recent gas) but wait to be sure it continues for multiple seconds later. -put something under the hole to catch the gas so you won't be wasting- if all that check out then you might need to look at your jets. Did you replace them in the rebuild?

As stated, the issue is very likely fuel related. After checking all the above mentioned, you may need to go back in the carburetor again for another cleaning. Keep in mind, once you cleaned everything (carb, etc.) and got it running small fragments of trash get to moving around in the tank, line, etc., and get back into the carburetor, so I've seen cases where you have to repeat this a couple of times.

Sounds like you are getting more air in there when going fast, so it could be the diaphragm isnt seated good enough or the slide its attached to. Take that apart and give it an inspection if you still have problems after checking the fuel.

^^^ I agree with ATC4ever ^^^

Pull the diaphragm and slide out of the top of the carb and look for a hole or gap on the diaphragm. They sometimes get cut near the outer edges or tear loose near the inner edges where the thin rubber joins the top of the slide. Also make sure you follow diaphragm installation directions during assembly... most new issues can be traced back to improper assembly. The service manual for your Rancher explains how you must hold the slide up with a finger while putting the top cover on. If you didn't do that, its probably not in place now or it has become damaged.

If there are no air leaks in your diaphragm (and it has been installed properly) your main jet circuit is probably plugged. My money is on the diaphragm though... if you've had that top cover off.
