I have posted the same problem on here before but can't figure it out. Pulled and cleaned the carb put in a rebuild kit new jets and stuff. The problem that I'm still having is she starts and idles fine every time. When I go to put it in gear it stalls. It is intermittent, this will happen for a few minutes than it will go. When this is happening i can reach down with my hand and pull up on the shift lever and just before it goes into gear it will stall. Also when i do finally get it going I'll be going down the road then all of a sudden it will cut out, if i downshift into neutral before it stops rolling it idles fine and i can keep going again. Is there any type of switch in that is connected with the shifter in the trans? it has been intermittent for a couple of years now. I'll have weekends when it doesn't do it at al,l and then sometimes it happens all the time. Sorry so long a post just really frustrated.:angry: thanks in advance

You have a neutral switch and a reverse switch either one will give you an issue if they are bad but they are not usually intermitten, they usually fail all together. If you set your Idle too low when you pop it in gear it will cause the engine to stall too.

turn your idle up..and did you check your fuel pump ?..it has a elec fuel pump on it..it also has a fuel pump control box..right rear behind a black cover. this tells the fuel pump to shut off after it reaches so much pressure
the fuel pump is pulsating about once every second don't know about the control box or what to check there. tried the idle doesn't change things. if i warm it up sometimes it will go get 100 yards and stall,stall,stall, then all of a sudden it will go and run for hours. if i turn it off sometimes it will go and sometimes it will go thru the stalling again

check your float needle..from what your saying..it's running out of fuel..start at your gas tank..and go from there to your carb..i think your float is sticking..and your running out of fuel...if it runs fine when you first start it..then yeah..it's running out of fuel..about a 100 yards..and yeah..you used up your carb bowl gas..and it's not re-filling back up...check your float needle..make sure it's not sticking...also check your float itself..make sure it's set right.
i just replaced all the jets and the float needle pin. this has been going on for a couple of years. sometimes i can run it for four days without a problem then it will do it again constantly then it may go away. it seems to happen in bunches sometimes it will do it very often and sometimes not at all

good luck on that !!..lol..number 1..even if you can find one..thats gonna cost about 200 or more..second..no..you do not need a oem fuel pump..do what i did..go to advanced auto parts..tell them you need a low pressure 12v fuel pump..they are around 40 bucks..their round..i think they are about 4 psi..somewhere around that ??..they fit perfect into the same holder..only thing you will have to do..is redo your fuel lines..they will be different angles and so forth..but..for the price..you can't beat it !..oh..and you will need to cut off the leads from your old fuel pump..and splice them into your new fuel pump..use butt conectors..they work great.
Thanks for all the help Shadetree i just can't understand why this is a intermitten thing, you really seem to think it is a fuel issue though? like i said before when i reach down and pull up the shift lever by hand just before it goes into gear it will stall. i can let the shift lever down and it will idle fine> What I'm saying is that i don't put it in gear but just before.

i'm not sure it's a fuel issue..but..it never helps to rule it out by checking it..but..after doing some thinking..you say it will idle just fine..but when you go to put it in gear..it stalls..this tells me your centrifugal clutch isn't working..this is more known as the pto clutch where i come from..lol..they are hanging up..or the one-way bearing is on it..check it out..remove the left side cover..see if you can turn the outter housing by hand one way..and not the other ?..if it turns both ways..your one-way bearing..or the arms inside it our worn..or just bad..just start with fuel..make sure it's getting plenty of it..check your air filter..make sure it's clean..then move on to the pto clutch check.
Hi ironsetr, I have the same machine with the EXACT same problem. It's NOT a fuel issue at all. I found out the hard way, I rebuilt the carb, and also replaced the neutral switch (along with the reverse switch and the oil temp sensor just to be safe) but alas that did not fix it either. The culprit is the fan control module. It is a black box located under the front left fender with six wire leads coming out of it. There is a similar box on the right side, that one is the CDI. The dirty little fan module is responsible for all that ails your machine. Instructions for replacement? Glad you asked, gently remove old fan control unit, place on ground and smash repeatedly with a hammer, this helps recover your spent chi. Gently install precious new fan control module. Just so your aware the module has been discontinued by honda, but I saw several used ones available on ebay and occassionally a NOS one comes around. The part # is 38710-HA7-671. I've run into several other people who have this same problem so I'm going to post the solution to those as well. Hope this helps, good luck!
Stalling in gear
The issue is the fan control module. It not only controls the fan but also the warning lights. When it shorts internally it will also cause the stalling problem when you put it in gear. Frustrating problem and hard to track down, I found out the hard way after rebuilding my carb, and replaceing the neutral and reverse switches, and the oil temp sensor. It's a black box located under the left front fender. The part # is 38710-HA7-671. Instructions for replacement? Glad you asked. Gently remove old fan control module. Place on ground and smash repeatedly with a hammer. This helps recover your spent chi. Step two, gently install precious new fan control unit. Ride off into sunset. Hope that helps!
