Hi everyone. I bought my kids a used 2003 TRX 90 for cristmass. Because it was kind of last minute I didn't have much time to make sure it was 100%. I found out that the fuel in the tank was old and it ran very rough. Tonight I changed the oil, cleaned the air filter, changed the spark plug, changed the gas, took the bottom off the carb, pulled the main jet and cleaned it. I put everything back together and now the carb leaks gas out the bottom tube when I tuen the fuel on. I have taken it back apart twice and checked the float and everything appears to be in order; but it still leaks! Any suggestions?

You may need to rebuild it you can get a kit for around $20. The float valve could be worn out. When you cleaned the carb did you go through the whole thing?

Thanks for the welcome. I didn't do the whole thing; I was trying to shortcut so that I could get the kids back on it tomorrow. I should know better. Is the float suppose to connect to anything? I took it off and put it back on and it appears to move freely.

More than likely you dislodged a piece of trash in the Float needle and it's keeping the needle open allowing the bowl to overflow. just take the carb off remove the bowl and the rod that holds the float and needle in spray out the passages and reinstall. that should cure the problem.

Thanks

When I looked at the diagram Mudd99 posted I realized that when I took it apart the needle valve must have fell out. I checked the floor and sure enough that's what happened. I put everything back together and my 9 year old has been having a ball on it. I think I'll end up rebuilding the carb. It still runs a bit rough although better than before. Thanks!

Good deal!! Run a can of seafoam in the gas that will clear it out.
