Technical | How To / Re: Espresso 150 cuts out when throttling

Thanks to all of the suggestions ... I got it running!!! Woo Hoo!

Aside from replacing the spark plug (which was somewhat blackened), I dismantled the carbi as shown in the video, cleaned it all out, put it back in, tightened everything up and gave it a start. Within 30 seconds it was revving beautifully. I will still check for air-leaks as it's something I should probably now that I've just put together my first carbi.

Thanks again for all the support, ideas and help.

Cheers,
Af.

Thanks. So short of rebuilding the carbi, how do I go about getting a cleaner into it? I have some carby cleaner here but not sure where exactly to spray it into?

The instructions say to take the air cleaner off which I can do (that's the large pipe going from the air filter to the carbi). Then it says to spray in burst inside the carbi throat. Is that where the air cleaner pipe joins to or somewhere else?  ???

I have the kymco service manuals here so could probably pull apart and rebuild the carbi but I'm trying to avoid that if at all possible.

Thanks,
Af.

Thanks so much for the quick reply Vivo. I really appreciate it. Fuel starvation is most likely the issue here I agree (based on my limited knowledge of these things).

Checked ...
  • Air filter is very clean
  • Fuel lines have no kinks that I can see
  • Fuel cap on/off makes no difference

I found the pilot screw and made a few adjustments but it didn't seem to have any impact at all to the RMP at idle that I could hear, except when it was almost closed. I've returned it to the original setting.

I've put up a video to hopefully help diagnose the issue. I can focus in on particular areas if it helps. Just be my guiding hands!


Cheers,
Af.

Hiya,

Just got a second hand Kymco Espresso 150. Only done 1000kms and is very good nick with RWC and recent service. Got it home and am finding that it starts ok, but when I hit the throttle it cuts out suddenly. There is no spattering or chocking kind of action, just a sudden drop dead.

I can hold the throttle at a very low power to get the back wheel spinning (on the stand) with no troubles, but as soon as I give it a little more (even slowly) it cuts off.

So far I've checked the air filter and that all looks very clean. I adjusted the idle but no luck there either. Found the spark plug but can't get the damned thing out to check it as it's screwed in quite tight and is difficult to reach. All the lines look good with no cracks. I'm not very good with mechanical things (wooden things, no problems though!) so any advice or thoughts would be great.

I'm hoping to bring it into a service centre but everywhere seems closed until the new year. :(

Any thoughts?

Cheers,

Af.
