Hi, all new to this. I've a 2005 Vespa LX50 which has been running great until September when it would bog down, engine keeps running but feels like there is too much or too little fuel.
Had the carb off, cleaned, new float and pin, new vacuum pump, new fuel hoses, new air filter, new spark plug.
I did get it kind off running ok'ish, but it would still always bog down at 3/4 throttle or if trying to get up the slightest of inclines.
Now I can't get off the driveway and i'm at a total loss, been tuning (trying to tune) the carb and when it's on the stand it runs smooth but the moment I put it under load it bogs down, yet on the stand you can rev it to your hearts content without issue.
Engine never stalls and if you stop the bike for 10 secs or so you can ride again until it bogs down, again.
If anyone has any ideas what may be wrong, I'd be very happy to hear.
