Speedfight won't start after cleaning carb

[bass2k8]

I have a Peugeot Speedfight 100 Prost, 01 (2000) plate scooter. I attempted to clean my carb, following the instructions from a haynes manual.

Relating to my previous topic ( https://www.bikechatforums.com/viewtopic.php?p=2808631 ) where my speedfight had problems accelerating past 20mph I decided to clean my carb to see if it fixes the problem.

I'll talk you through each step that I did so you can identify the problem I may have.

1) Remove the rear body panels, disconnecting the rear light connections and boot release key cable.

2) Take off the seat, and remove the boot casing.

3) Detach the fuel line and vaccum tubes from the fuel tap.

4) Remove the fuel tank, detaching the fuel monitor cable.

13) Unscrew the bowl from the carb and cleaned with petrol.

14) Remove the main jet.

15) I noticed there was some crap in the Main Jet, so I got a needle and poked it through.

16) Reinstalled the Main Jet, and Screwed the Carb Bowl back on.

17) Reattached the Carb to the Grips and fastened them.

18) Reinstalled the Automatic Choke to the carb.

19) I Reinstalled the Throttle cable to the carb and then noticed that the throttle was really loose to turn. There wasn't no friction to it, so I removed the throttle cable from the carb. I then twisted the throttle to see if there was any difference and there was, it felt just how it should be. I have tried many wasys of inserting it back into the carb and it still feels very loose.

20) With the throttle cable installed I had a look inside the carb and noticed the throttle needle was in contact with the main jet, and when I twisted the throttle the needle did not move.

21) I decided to leave it, and reattach the fuel line and oil tubes to the carb.

22) Reinstall the air intake pipe.

23) Reinstall the air filter rear casing, and then install the air filter.

24) Placed the petrol tank back where it sits, and attach the fuel monitor.

25) Reattach the fuel line and oil tubes to the fuel tap.

26) I then went to start up my speedfight and it just wouldn't start. Watch this video to hear how it sounds like: https://www.youtube.com/watch?v=hn1MvlO7lAM

27) I then checked to see if everything was correctly connected and it was.

28) I removed the air filter and air intake pipe.

29) I noticed to the right side of the carb I could feel a suction as I attempted to start my speedfight. I then placed my hand over it, and then went to start my speedfight and it started... but one problem it was at FULL revs, it scared the shit out of me haha.

My theory of this whole thing is something to do with the throttle needle. I don't know what to do so I am looking for advice from you wonderful people. Thanks for taking your time to reading this topic, I highly appreciate it.

I suggest you take it apart again and re assemble slowly and carefully to make sure you have everything in the correct place.

I would not advise using a needle to clean the jet, it could scratch it and ruin it.

[bass2k8]

Everything inside the carb is in the correct place. I made sure of that.

People have been saying that it may not start because there isn't any fuel in the carb bowl to ignite with... they asked me to use the kickstart a few times to put some fuel in there, but theres a problem my kickstart doesn't work.

What I did instead was manually put some petrol into the carb bowl and screw it back on with the fuel in there. I have not tried starting it up yet, because my battery has died at the moment so its now charging.

I really need this working as im reliant on it to travel to college and work!!

you might want to make sure you have refitted the carb to manifold gasket the right way up, if it's upside down you will be sucking in air.

Edit: just realised this is a 100 so doesn't have the bolt on carb so pay no attention to the above

Carb looks like it was pretty clean, doubt there was any need to do it. When they're in regular use they don't really clog up, it's just when they're left for any time that the petrol gums up and coats and blocks stuff. Don't poke needles through jets, they're soft brass, a blast with carb cleaner would likely blow anything out or just soak it in some and use compressed air.

As for the fuel, it was probably just an empty float bowl, depends how long you tried to start it for, takes a little while of cranking to fill the fuel line and float bowl back up. You also haven't mentioned reattaching the vacuum line to the fuel tap, make sure you did it and that it's attached at both ends (engine and tap).

[bass2k8]

What is the manifold gasket?

Is this it?:

If so then yeah its fitted correctly. Hmm there must be something wrong with the vaccum tap operation then. Please explain more about the manifold gasket.

have u got your pipes on right? i had this problem with my bike too and i used easy start and sprayed it into the carb then tried to start it and it fired up straight away. this would help get it running then u can adjust your idling and stuff while its running. just make sure u have the pipes in right and the carb has been fitted together properly. you can buy easy start from any motor shop or halfords its a few pounds and comes in a spray can. hope this helps

I have got it working now so it doesnt matter I dunno how I got it working, but the throttle needle casing that slides up and down seemed a bit stiff so i moved it around a bit, then started it up and it worked

And oh I had my kickstart's pinion gear snapped, so I had to replace the whole kickstart mechanism, got a new pinion gear, kickstart quadrant and friction spring. But the thing is that it doesnt spin around when u kick it, it gets jammed... I've taken it out and in many times and it still doesn't fit properly... i may need to get another kit as this one was USELESS.
