I have cleaned the carb multiple times even after I got the carb kit for it. It seems to cut out when I hit full throttle. Any suggestions?

Replaced spark plug, checked connections.

mine was cutting out at full throttle because it was not getting enough air.


i had a few pair of socks on it, pulled them off and no more cutting off up top. it was flooding out. pull the filter off and see if it helps any.

Have you cleaned the air filter? have you checked the plug for rich or lean condition?

 

[blowfishRus6]

yea, if you check the plug it will really let you know whats going on.

black would be to rich, white would be lean. your shooting for a brownish color.

I am pretty sure that it is not getting enough fuel. There is a brass piece in the throat of the carb that the jet needle goes through before it gets to the jet. while watching through the the carb the brass piece rises at full throttle. if i spray gass through the carb it will reach full throttle but does not have enough fuel to stay there. It will idel great but as soon as you give it gas it falls on its face and dies. It runs better with the choke on. I have cleaned the carb several times now. The spark plug is black and dry.

black would mean its rich, thus getting more fuel then it needs.

Check the screen at the bottom of the petcock (fuel on/off valve) it could be plugged up with crap and cutting off fuel flow. You can remove the bottom bowl of the valve and the screen and a plastic clip will come out. Mine was very full of rust as well as my tank, I put some screws in the tank and shook it till my arms hurt then spent the next two hours fishing out the screws, cleaned the valve and the carb and added an inline fuel filter in the process to keep that junk out of the carb.

If you have a carb kit in it and sure its clean and your air filter is good try running it with the air box lid removed see if that makes a difference, however if your plug is BLACK that does mean its rich which means too much gas so maybe the float is out of adjustment, or has a hole in it or is sticking?

I assume the carb kit came with a new main jet. Did you make sure its the right size? It should be either a 120 or 125 main jet.

bodee1212 you need to clean the carb and try to run it for a little bit and then check the plug again running with the choke will cause the black coating on the plug and give you bad info. not saying thats not the problem but you have to set the condtions to get the correct test results

I cleaned it again and let it soak for 24hrs. I put it back together and its doing the same thing. How do you tell if the float is bad? Other than fuel being in it or a hole in it. There are no holes in it and there is no fuel in it.

If it runs better with the choke on then you are not getting enough gas. Since you have a carb. kit installed what size jets are you running? When you clean the carb. do you just soak it or do you clean the jets and all the carb. body passages?

 

[Bodee1212]

I have blown out passages and soaked the carb and all passages where clean. I looked at everything possible and nothing I could do would help it get the fuel it needed. I found a cheap new carb on ebay so I just bought it. So I didnt have to take that unit apart again. Thank You for all of your help!

 

[blowfishRus6]

what jets did you have in it??

It came stock with a 125 main and I put a new 125 in it. I just decided to replace the carb because I could not figure it out and after messing with it for to long the primer plunger began to leak fuel and I did not want to keep throwing parts at it. I talked to a local honda shop and he said that they have had a few times where they threw all new parts in the same carb and it still did not run correctly. In the long run they put a new carb in it as well. I have never used this site before for help. But from here on out I will use this for help and to maybe help others. I like the quick responces and how everyone helps eachother. Thanks
