2003 Recon Goes Dead UpHill - Honda Foreman Forums : Rubicon, Rincon, Rancher and Recon Forum

XoDiViAoX · 08-24-2009, 11:00 PM

Hi, I bought a used 2003 recon with a recently rebuilt engine. It runs and sounds great, and has a lot of power, but every now and then it dies when I'm going up a steep hill, or have just went over a steep hill and leveled back out. It also kind of sounds like a soft backfire like sound when I'm in 5th at high speeds and let completely off the throttle to roll to lower speeds. (It doesn't pop and make a loud noise like a backfire, but it kinda reminds me of a soft sounding backfire)

I had been messing with the pilot screw idle screw and i never got it where I wanted it, so I took the carb off, it did have a couple pieces of black specs in the bowl (very small specs, it pretty much looked really clean) I blowed them out with an airchuck and blew out the jets.

Has anyone ever experienced this? Does it sound like I don't have the pilot/idle screw adjusted properly, something wrong with the carb, or another problem?

Thanks hope someone can help.

Frist off

to the Forum!!!!

Sounds like you might have had some trash in your carb
and sense you have cleaned that out you might also want to
clean the fuel filter out that is in the gas tank, remove your
petcock and flush it out

also your float sounds like it is either out of adjustment or sticking

here is the Topic on tuning a card

put a t fitting on your carb drain tube, let one drain, and run the other up to your stock snorkle

same happened to mine

Soulds like the float is sticking...did you take out the valve and seat?

Does it die right away going uphill or does it take a little while? I would make sure the vent lines (hoses) are clean and you can blow through them (carb vent and gas tank).

yes as soon as you go up it dies like no gas checked tubes all clean maybe float sticking i cleaned it in carb dip ???

**toodeep** · 12-22-2009, 06:27 PM

I don't have many ideas for this. Possibly something in the air intake tube and when going uphill it blocks the flow of air??? Water in the fuel and it gets a pure shot of it when going upwards???? I'll have to think about it and see if I can come up with any other thoughts.

One last thought might be your float level is too low in the carb (&/or sticking).

Bossy 70 · 02-03-2010, 04:21 PM

Yes, I would check your vent to the top of the carb. If it is clogged your carb would use your overflow on the bottom for vent, but if the overflow gets water stopping it up or fuel stopping it up (when going up a hill) it can cause your atv to shut off.

My recon had a factory lean setting for the idle fuel mixture. It was 1.5 turns out. I might would try 2 turns or something in your case. This can cause your lean backfire on deceleration.

Hope you find out whats going on.
