This guy has a 2000 model Vespa LX50, that he told me has a bad fuel line. I say no problem, come over and replace all the fuel and vacuum lines with good ones, and throw some new gas in. Everything looks great, good flow from tank Diaphragm and no leaks. After cranking it for a good 5 mins, it finally starts with the Throttle WIDE OPEN. Then SLOWLY gets going and I can let off the throttle, SLIGHTLY. If I let it completely close or go back down to IDLE, it DIES.
I DID NOTICE: It is MISSING the clamp on the INTAKE side of the Carb. The hose coming from the Air Filter Box. I know these things a picky when it comes to AIR/FUEL mix, and I just wanted a second opinion, before I take the valve cover off and check the valve clearance. THANKS SO MUCH GUYS!
Sorry Cyborg, so used to posting in the general 50/200, totally forgot there is a Vespa section!
Thanks a lot guys, that is what it was. I went and grabbed a hose clamp that would fit, got it put around the intake hose, and adjusted the idle. Fired up with a good high idle, then I heard the electric choke start to move and now she is purr'in like a Vespa!
IF it was mine, I would've checked the valve clearance too, but they didn't wanna pay for that! hahaha She did however want to bring it by my shop to get the fluids changed. The gear and engine oil both look like they still have the packing/shipping oil in the scooter. I told them to get that changed ASAP!!! Other than that, it is a NICE scooter! Someone re-painted it Baby Blue from Yellow, and the ODO only says 143 Miles. My guess is they got it to learn, Wrecked it, Painted it, and sold it to this guy for 1500 Bucks!!!
the missing clamp probably is a huge portion of the problem but you may want to inspect all vacuum lines ,,, and also i'd check the carb if that doesn't help you may have a sticking float that's slightly flooding it,,,,,or the tip of the float valve needle not be seating properly,,,just a couple thoughts
The clamp solved the issue, as far as I can tell. Had to get the Idle adjusted, but after the choke disengaged and she settled down, she stayed running for a good 10-15 mins just fine! She was happy, I was Happy, it all worked out! She said she would call if anything changed and SAYS, she would like to bring it by for the fluids change on it. I am pretty sure it still has the CRAP oil they put in it to ship it over here, and told her THAT would cause more problems than anything! Hopefully I will hear from her today to get it all changed!
Fluids on that machine will only be the final drive ,,, and if I'm not mistaken it's synthetic right out of the box , and if memory serves it's a 3600 mile first change,, it is a 2 stroke correct?,,, just make sure she keeps an eye on the oil reservoir so she doesn't run it dry and ruin the engine
