I was out on my way to the market and the scooter seemed to be running well. It was moving at 45 mph at WOT but when I pulled over to turn into the parking lot it simply died. I managed to get it started and drove around the parking lot and it seemed ok so I went in and got my groceries and came out cranked it right up and drove off into traffic.. After about two miles I made a left hand turn and then accelerated away as normal but when I slowed again to make a turn the engine died again and refused to start leaving me to walk it home the last half mile. I continued to work on it at home. The spark looked weak so I got a new plug and the scooter started right up but died immediately and would not restart. I finally cupped my hand over the air intake and the engine would start and idle as long as I would keep some of the air choked off. It would also run with my hand removed from the intake when the throttle was applied but as soon as I released the throttle it died unless I had my hand back over the intake. BTW the vacuum caused by my hand sucked extra fuel into the throat that ran out on the shop floor. I assume that the low speed circuit is screwed up but don't know where to go from here. It is carburetored with and starter enrichment module rather than choke. |

I worked on it while listening to the second half of the LSU vs. Arkansas game. I suppose about an hour and a half total. So I guess I earned $250/hr. |

Knew you could do it Phil! Subtract your expenses, then divide the remainder of the shop estimate by your hours in fixing it....you made a dandy hourly rate! being an automatic, you can simply put her on it's stand, lightly apply the rear brake while increasing idle speed. When it just starts to fight the brake, back it off till it stops fighting. Then when on it, if it still tries to pull slightly, just back it off a tad more till you're good. |

I finally got a chance to read the tech manual on the carb and decided to dive into it today. I was pleasantly surprised that it is a very simple set up. There are no needle valves to set and the float level is a go/no-go situation. If it don't work you replace it. I inspected the diaphragm and found it only slightly dirty. I guess reassembling the diaphragm chamber is the trickiest part of the reassembly. There was a little dirt in the float chamber but none noticeable in the float valve, main or low speed jets. I put her back together and installed a good filter in the fuel line.
When I tried to crank her up I thought I was skunked because though she was hitting I couldn't get her to fire up and stay running. It was at that time that I realized the "technician" had apparently turned the idle stop screw out too far trying to get her to fire up. I turned the screw in a full turn and she started and ran at a very low rpm. I did a little more adjustments and had her idling smoothly. The engine is supposed to idle at 1600-1800 RPM but I don't have a tach other than my mechanical tach and there is no access to the crank shaft without disassembly. Regardless I took it out and ran it about 10 miles and she ran like a top and never missed a lick. It could still be that I need a cold start fuel enrichment unit but a cold start tomorrow should reveal if it is malfunctioning. Total cost of repair was approximately $9. $3 for carb cleaner and $6 for filter and hose clamps. Confidence building? Priceless!

Well probavly but I think Honda had special tools for carb service as the tech manual instructions describe removal without removing anything other than the left side panel. I may end up pulling the engine or the rear wheel and fender. We will se. |

Carb. was installed before the engine? |

Dave, the manifold is designed to capture both nuts at either end of the manifold on the inside. There is no room for a socket of any type and certainly no clearance for an extension. I was thinking a 10mm crow's foot with 1/4" drive. |

Phil that is a real handful for such a small engine. Hope your successful with your project.

Phil. When you put the carb back on try using a 1/4in drive short extension and thinwall 10mm. socket. If you don't have one that is very thin it is worth the couple of bucks to get one from one of the "expensive tool trucks". Put a little old fashioned window putty or similar in the socket and press the nut into it. Putty will hold nut for you so it doesn't drop out. Start on stud with only ext. at first. Use ratchet to finish tighten before you put air intake back on. Good luck with your project. Daniel I agree. I have been riding motorcycles on the street for 45 years but skydiving etc. go beyond my personal threshold of things I don't want to try. Dave. |

Teresa loves to go riding motorcycles with me, but we don't get much time to do it. No matter what you do, there are horrifying stories connected, whether riding motorcycles, or just slipping getting out of a bath tub. Life's too short to live in fear of all the fun things. Having said that though, you'll NEVER catch me rock climbing or skydiving, among other things. I do have many personal limitations! |

I went to the shop and picked up my scooter, still shaking my head over the amount they wanted to charge me. 
I started taking her apart and managed to get the carb off in about 20 minutes even though there is absolutely no room to get my smallest 10mm combination wrench in between the fender and the engine cowl and reach into a blind pocket with the open end. All I could do is turn the nut on the manifold about 1/16th turn at a time but it was enough to get her loose. The nut on the outside I can turn with a box end but I am more concerned abut getting her back together and retightening that inside nut.
Now I come inside and read up on how to take the carb apart and clean. |

I saw some photos of a four wheeler that ran under a truck while the guy was texting " what are you goi......". They were pulling him out in pieces . His legs were trapped under the steering wheel and his body minus head was in what was once the trunk. Car was totally unrecognizable. Luckily he was by himself. He was just dying to text. |

I don't know if I could have been able to even comprehend that price. Honestly can't imagine how I would have reacted.
My wife was a first responder and one of the training films was called "Death on two wheels". Just happened to be on an evening when I went along with her. Not the sort of film that the general public sees. That was nasty. If they ever come out with one called "death with two wings" I will probably quit flying. My wife has been supportive of my flying but is real leery of motorcycles so I know where your coming from.

They planned to ream you out good didn't they! All it should cost is some time & a can of carb cleaner spray. Patience is the main ingredient. |

Wife was pleased to learn I wasn't going to get it fixed. But was disappointed that I intended to do it myself. She worked the emergency room while in nursing school and said they had so many accident victims that were horrendous so she would just as soon it never ran again. |
