I have a 2007 Honda Recon 250 and I'm having issues getting it started. I have to play with the choke to get it started. Usually takes a couple minutes until it will start to idle long enough that I can open up the throttle and stay on it. After I'm on the throttle for 30-60 seconds it runs fine. And when it's warmed up I can shut it off and start it right back up. But the initial start is always a tricky and long process. Any help is appreciated!

sounds like a complete carb over haul is needed.

I put a brand new Honda carb in it a couple weeks ago. It started soon after I did that (ran fine the first couple times riding it). New carb probably has 4 hours of ride time.

when it dies, are you checking the spark plug for spark right then ?, if its getting spark ?, then its not getting fuel from the tank.

My guess is fuel related but have no idea what to check. If it's spark it shouldn't matter if it's hot or cold. But I know the carb is getting gas. When I pull the fuel line gas is flowing. Doesn't make sense to me that the issue is only when it's cold. Any help in next step troubleshooting? Thanks guys!!

I got it from Partzilla so I'm sure it is an oem carb. I The intake boot is in good condition. I haven't adjust the valves to be honest I have never done that. Could look into that if that's what the issue could be.

before you go messing with the valve adjustments !, pull the carb back off, have a look through the jets, see if the idle jet picked up any tiny trash from your fuel tank ?.

If that was the case why would it run ok after it warmed up? Just curious. I'm still a newbie to all this so sorry for the dumb questions! :)

yes and no, when they are cold, you normally would need to choke them, then as they warm up, they then start using the idle jet to run, then when you open the throttle for more speed ?, it switches to the main jet. soooo, at idle on a cold engine ?, it draws fuel from the idle jet, and this jet is very tiny !, it doesn't take much to clog this jet up.

That actually makes a lot of sense, thanks for the explanation. Maybe another dumb question... how can you tell if there is a tiny piece of dirt stuck in the jet?

Ok, a quick search and I found out how to clean it. Thanks for the recommendation. I'm going to give that a shot later on today.

answer: remove the smaller jet ( idle jet ) from the float bowl, hold it up to a light source, you can barely see though the center if its clear ?. if not ?, its stopped up !. if its stopped up ?, take a strand of wire from a wire brush..like you would use to scrape rust off something ?, use it to run/poke down through the center of the jet, go easy !!, you don't want to break the wire off inside the jet !!!.

Thank you and shadetree! I have a CFMOTO Uforce 500 that is doing exactly the same thing! I have been working under the impression that it has to be the choke. But now I am thinking that I really do need to clean the carb. I live in extremely dusty Arizona, and I just got a snorkel on the air filter to get it up out of the dust cloud, and the choke is coated with very fine dust. Nothing helps my problem. So I will be checking out the idle jet.
