So I've had my bro-in-law's 4 wheeler to get it running again.
Ended up buying a new aftermarket carb, cleaning fuel tank, cleaning petcock and it works near perfectly .
put the petcock to PRI for about 5 seconds , turn it back to on, pull full enrichener , start it up (starts right up), slowly release the enrichener and put it in gear and go up down the road. Slow, fast, idle etc all good
BUT then out of the blue it will start missing badly (by this time the motor is hot), to the point I can't move the ATV.
Then out of the blue, maybe 30 seconds later, it is back to normal and I can go up and down the road for testing just fine.
I'm trying to get the ATV in tiptop shape to return to him, but bugged by this miss, I'm sure this machine will come back to me if it keeps missing...
Thanks in advance
BTW I am mechanically inclined, but not an expert on this atv...
recently picked up some project bikes off CL for cheap. got a honda fourtrax (the ancient 4x4 kind with the straight axle in the front as well as the rear and a back-up kick-start) plastics are crap, but my goal is to get running like a champ and patch the plastics up and sell to one of my many friends that want a reliable 4x4 for dirt cheap and doesnt care what it looks like.
so the former owner says it needs carb rebuilt, but its sat for 3+ years since so who knows. things I see: carb is missing (he gave me a box of parts along with the bike), engine turns over and feels good with kick-start, brakes need work, battery missing (That always puts me off, cause then I know most likely someone's been tampering with the electrical.

Hi guys. First post, hope you can help. As above 1991 Honda fourtrax. Starting, running fine until a few weeks ago. Used primarily to put my ski boat in the garage (put 2" ball on front). Any way, had just backed boat into garage, turned off to crank trailer wheel down, when I went to restart got nothing.
No neutral light, no headlights, no reverse light, would not turn over when start button pushed. It would crank and run when I jumped the contacts on the start relay. While running the neutral light will come on, although it is dim and flickers. Reverse light on when running and in reverse.
What I have done to this point:
1. Used jumper cable to ground battery (-) terminal to engine block thinking ground wire from battery to engine may be bad. No neutral light, no start.
2. Applied 12 volts to start relay. Got a loud click like it was making contact. I didn't have the battery/starter cables connected to the relay, but I am assuming it would have cranked at that time.
3. Disconnected neutral switch wire. Grounded neutral switch wire with jumper wire. No neutral light, no electric start.
At this point I am thinking ignition switch vs broken wire in the harness going to the neutral switch (due to dimness and flickering when running).
Any and all suggestions to help track down this issue are appreciated.

I have a 1988 300 Honda FourTrax, All wheel drive.
My brother and I were fixing up this quad. We put a brand new battery and fuses in and it was running fine until we put the quad into reverse. As soon as it was put into reverse all of the electrical cut out and power wasn't making it to the head unit anymore and both of the brand new fuses popped. We figured there might have been a short from the starter or solenoids, but they are all working properly. At this point we don't know where to start looking for where the short could be. I'm just wondering if anybody has had the same issue or knows of similar issues that could cause these electrical shorts?

So I have a Honda Fourtrax 300 year 1988. The ignition doesn’t start it with no sound. The headlights won’t turn on. It has a brand new charged battery, fuses are good, oil is good, gas is good, reverse is rusted, it shifts good, won’t jumpstart but when you try it will turn over, it will start if you jump the solenoid give it gas and spray starter fluid on the breather but it won’t stay on long but will stay on for the little time it does by itself. I don’t know what’s wrong and I need help!
