Question about 2005 Honda Metropolitan Base

1 Answer

My Honda Met.2 Chf50 runs great with handkerchief on intake of carb but when you attach breather quits

My Honda runs great when I have my handkerchief over the intake of the carburator but when I attach the breather it wont run. I've cleaned the carburator. When I purchased it at a garage sale it didn't run. So I replaced the battery and that took care of that problem but this has me stumped. There are 2 wires on the top of the carburator that I do not know what they are for. I took them off and put them back. It has me stumped. I do not have a manual.

Hi, Monte the two wires are probably for the electric auto choke for this scenario you will need your service/owners manual if you can't find the best tool you ever bought for your Yamaha, despair not, for a mere zero $0 you can download another one.

SOURCE: % hp Honda Motor runs on choke

Dear LC39B,
Is it possible you are blaming the wrong part of the machine? Did you try the Honda Motor on its own? I am asking , because if the pump of the washer has some fault or a bit jammed, this will demand a lot of power from the Honda. You can try the Honda with no water connection and no gun.
Regarding the Honda motor, you should check the electrical system also. I am saying this because you did not mention it, in your service procedure.
Regards,
MG.

SOURCE: wont run...

Any water in the gas? Remove the water trap bowl at the bottom of the petcock, (gas valve). Any water or trash in the bowl? Drain a cup of gas from the tank. Any water or trash in the cup? Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ).

Get a fresh set of stock NGK spark plugs. Clean or replace the air filter. You seem to be pretty thorough in what you have done, but since plugs and filter weren't mentioned I had to ask.

Assuming you are getting air, gas and spark, and the timing is correct then it should run. Right? Not necessarily. Can the bike breathe? If pressure cant get out of the tailpipe the bike won't run. Mufflers can sometimes collapse internally. This restricts the flow of burned gasses. causing backpressure. If nothing goes out of the cylinder then nothing goes in.

Try removing the exhaust pipes. Now see if it will run. Get back to me because I would like to know what you find.

SOURCE: starts runs min. or two then stops....

Go to toro.com then click customer care, then click manuals and parts. Type in model no. and download the owners manual. This should get you the spark and flywheel gap. Probably still something in the carb. Some orifices are very hard to find and to clean but they must be clean. Also check for dirt dopper nest in the muffler.

Hi and welcome to FixYa,

Almost always, the solution is to pullout again the carbs and redo. Some ideas to consider:

  • overflow is always caused by the needle valve not closing the inlet seat;
  • too rich mixture could be caused by wrong air/fuel mixture adjustment;
  • you may also want to check how the carbs are fitted to the coupling to the engine intake as well as how the air cleaner enclosure/box fits over the carbs.
The above are just for starters. Post back result(s) or updates on any developments.

Good luck and thank you for using FixYa.

Starts and runs but will only go 25 top end and 10 going up a hill. I cleaned carb, and changed plug. Filter good. Any help about how what to try next?


Dennis, Write up found in scooter guide.net link below.This scooter was restricted to 25mph via a series of restrictions to the variator, ECU, intake and camshaft. 2009 was the last model year for this CHF50 in Canada and the USA, although this scooter was available for a few years after this due to excess inventory from the 2009 crash of the scooter market.
You can have it modified at a shop probably $$.
Check the attached links,instruction and guides, Good luck

Was riding. Why did it just shut off?


Hi, Sue the following applies to carbureted also fuel injected models and the usual suspects are:
1. Severely discharged or a damaged battery, 9 volts or lower.
2. Faulty alternator/generator and or voltage regulator.
3. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
4. Faulty main circuit breaker or ignition switch, check for loose connections and continuity.
5. Faulty system and or ignition relay, check for continuity.
6. Faulty ignition coil, ignition/electronic module.
7. Faulty CKP, CPS, CMP, MAP, TPS, O2, or BAS sensor, corroded, loose or broken wire connector pins/sockets.
8. Water or dirt in the fuel system, carburetor or filter.
9. . Restricted, blocked or kinked fuel line.
10. Fuel tank empty.
11. The gas cap is not venting properly or fuel tank venting system blocked.
12. A faulty Fuel Pump, pressure regulator and or fuel injectors.
13. Vacuum line from intake manifold to petcock broken, cracked, or not attached, carburetor vent line plugged.
14. Needle and seat stuck closed in the float bowl.

When I attach breather pipe to the side of carb bike gets very sluggish ,and when I take it off bike runs smooth , block one end of vacuum pipe that goes into carb? Or will I cause damage to bike ?


Carb vacuum lines are easy to misconnect. You have not listed your machine, or model, so I cannot determine what the details of the challenge you face actually are.
A description of your machine would help immensely.
Often a vacuum line from an intake is used to actuate a fuel valve.

2 lines running from the cylinder head into air intake is spitting fluids


Running into the AIR INTAKE, or the AIR FILTER/CARB MOUTH?

If the latter, it's the lines for the crankcase ventilation breather, and quite common for it to carry a little oil mist.

86 honda shadow VT500C flat spot in throttle about 1/4 throttle


The carbs are most likely clean, especially if they were soaked in real alkaline carb cleaner. Honda Shadows are very fussy about incoming air. If the air cleaner intake box is not fastened securely to the carburetor intakes the engine will run lean. The reason for the lean mixture is there is not enough negative pressure with the airbox disconnected and the carbs get too much air and not enough fuel.

There is a 2 second hesitation in my throttle when trying to accelerate to 2nd gear. Possible solutions?


Clean the carb plus check for intake leaks.
checking for intake leak warm your bike up take a can of WD40 while the motorcycle is running spray with WD40 with the nozzel attached around the carb joint/manifold if there are intake leaks the engine rpm will change then you will know you need to replace the o-ring or gasket or carb manifold/carb joint.

2004 honda crf 150 and all of the hoses are off of carb.?


Not positive but on two stroke bikes all but one of your hoses are breather and over flow hoses and are smaller than the fuel line that should come from the front left of the carb and go up to the fuel tank. the rest should come from the carb and have holders attached to the carb feed the line closest to the holder and fit it on the breather hole coming from the carb pertruding outward from the carb. there should be three or four lines and one fuel line.

Carburetor


It is located between the Intake Manifold on the engine and the Air Breather, which is under the seat. To remove, turn the fuel shutoff valve to OFF. Remove the fuel supply hose from the carb; it may help to leave it in place on the shutoff valve. Loosen the hose clamps that connect the carb to the Air Breather and the Intake Manifold. On the right side of the bike, you will have to remove the cover and cables for the throttle control. The cover should be held on by two small screws. The cables will come out of their grooves, but you may have to work at that a bit.

The diesel prob is carbon build-up. Replace the sparkplugs, check that the exhaust is not blocked. Check for spark and fuel if it still won't start. A simple way to clean the carbon out is to get the engine up to operating temp, remove the breather and with the engine running at about 1000rpm carefully feed it clean water down the intake. Don't over-do it! A drink bottle works great, but just a bit at a time! You will see quite a lot of dirt come out the exhaust. Put the breather back on and take it for a rip! Frankster016
