Hi, new honda owner, old retired guy here. Have a 2003 honda recon 250. Shortly after purchasing, I purchased a new carburetor online (offered by Zoom) because I was having carb problems, rough running, cold starting, etc. Fussed with it for days and finally just bought the new carb. Installed and all the problems were solved except the cold starting. (Cold weather starting, I mean. Warm weather still had to turn it over on choke but did start better.). Lately I was having to pull the air filter and hold my hand over the inlet to the carb to get it to start. I assumed that the mixture was too lean so I have been attempting to adjust. Only succeeded producing a new problem of bogging down when I advance the throttle from idle. Nothing I do to adjust seems to work. I would truly appreciate if one of you knowledgeable individuals would be able to help me get on a good troubleshooting path so I can get this operational again. I’m mechanically inclined, just not on gas engines. Thank you in advance for whatever assistance you can provide.
