Hi .........
In your case I would suspect that your timing is retarded and the bike would run better/correctly if you set it to factory spec. Or maybe you have a mechanical 'advance' and it's stuck in the retarded position?
Good problem ............ let me know how you get on

The presence of water on the plug, lead and cap play havoc if old or hardened. Replace the cap with a newer "long sleeve" rubber boot that covers more lead and a real tight grip on the ceramic of the plug.

Spray some WD-40 aroung coil wires. You can make up a simple guard from aluminium tape to stop water spray encroaching coil from front tyre.

Check that there is no obstruction on the rear head fins allowing any deluge to fill sparkplug recess.

Ensure there is a good sealing gasket on your left side generator/stator cover and they cover is not distorted or loose.

Good idea to wrap one turn of insulation tape on the bars underneath the switch cluster to stop switchgear shorting out on handlebars when really wet.
Cheers.

My 1968 mustang wont idle when I lift my foot off the pedal. But it will idle when I step on to the pedal. What do I do?


If you look at the throttle linkage on the driver's side of the carb you will see that it should rest on a screw at idle. Turn that screw in a little should solve your problem.
If that doesn't fix it then you will have to adjust the mixture screws in front.

1985 Ford Bronco 2 choke plate not closing


The choke butterfly (choke plate as you call it) can only be partially closed when the engine is cold. It is used to create a low pressure under in the throat of the carby which causes excess fuel into the engine when cranking and early running to help warm up and to prevent the carby icing up. After a few minutes the butterfly will be fully open and remain that way while the engine is at operating temp. As to the engine stopping down the road look for another fault -- Like incorrect fuel cap on tank , blocked fuel filter, dirty air filter If the engine starts easily and runs I doubt that the fault will be in the carby.

On my new 49cc 2stroke brushcutter what position should the choke lever be up or down when I put to up it cuts out even though up says off and down says on


Remove the air cleaner and look into the throat of the carburetor. Move the choke and watch the butterfly plate whether it closes or opens. Normal position is open--closed is for starting and warm-up. If the machine won't run with the choke open, return the machine to the dealer for adjustment. Hope this helps!

Hello, i have a yamaha dt 125 r motorcycle and I have a problem release the front chain gear because the whole engine turns while i am trying to remove the nut from the gear.W hat should i do?


Did you try an impact driver? How about putting the bike in low gear? If not, just get a breaker bar on there an whack it with a brass hammer. I'm pretty sure it is a right hand thread. Hope this helps.

2001 mercedes c240 has a really rough start but when the car almost dies I turn the car off wait 3 seconds and it starts perfect. Next comes the issue with having to warm it up before driving anywhere...


Gasoline- thank you. Warm up is not an issue like diesel is. Sounds like the choke is is either wide open or over choking. With the engine cold, remove the air cleaner and note where the plate is at the opening of the carb. If it is wide open then without touching anything else and engine not running, step down on the gas pedal and see if the choke plate reset itself to restricter the carb inlet. If it didn't, then take some WD 40 and spray the linkages and the rod ends holdin the choke plate.By hand work the plate and linkage holding the gas open at the carb. Then set the plate to wide open and do the gas pedal thing agan to see if choke sets itself back to restricting the carb intake. If it does, start the engine and as the engine warms upm the choke plate should start opening on its own and you are off and running. Roitine question. Is your air cleaner clean? If the choke plate needs adjusting. get back to me. K? Good luck Remember to press the gas pedal down once before cranking. That sets the choke for cold start. Hope this helped you Good luck Note, the WD40 won't hurt anything but avoid spraying with engine running or when engine is hot..

Usually, there is a way to adjust the position of the choke. I've seen two ways:
1) The electric assist might be able to be rotated or re-positioned by loosening its screws.
2) The choke positioning lever can be bent or extended by straightening it with pliers to fully close the choke plate.
