"What kind of carb do vespas usually come with?" ,,,it may have had the dreaded walbro carb,,,a bigger pile o kaka was never invented,,this is probably why the carb was changed to a chinese keihin knockoff,,,,change the battery look at the carb inside,,,and also the vacuum fuel taps are very suspect of failing very fast,,,i had to change mine at 200 something miles and eventually the carb with a vm series mikuni,,,the best thing that ever happened to that thing,,,they ran the walbro for a couple years not sure if this year falls into those years when they were used That was over a month ago, I finished getting that on the road soon after posting. Cleaned everything etc |

I just turned the flywheel in forward rotation until I was sure oil was flowing. I don't like the idea of running with an open cover, too high chance debris or litter (this is Boston) will fly in and I won't be fast enough to remove before it gets thrown down the chain.

So I picked up an engine for a spare, got it for free so no biggie, when I turn the flywheel I get to the T and it gets stuck, and if I turn it the other way it gets stuck about a half turn of the flywheel. Seized piston maybe? Is that how a seized piston would act? If it is can I ditch the topend and put on another topend? Never seen a seized engine in person before so I can't say for sure if it is what I think it is till I order some topend pieces at least. Try Astroglide  I don't think so lol. Gonna take a look later, all the heat and humidity is keeping me from spending real time on anything. |

If you have a 50cc you will most likely only use the 0.003 and/or 0.004

Let's hope it's just the CVT belt of something easy like that ... Nope, I changed the belt to a bando and still the same issue. The only thing I haven't tinkered with yet is everything between the valves and the crankshaft.. |

Also forgot to mention, the engine ran with a sawed off exhaust tube to make it loud it's entire life, it has about 500 miles on it. I see so many scooters in Boston with sawed off exhausts, then wonder why I don't se them anymore a month later, I bet this is why lol, stupid kids.

well fawk, breaking in a new BBK on what was a good running bottom end that had been sitting, maybe a oil problem....cause that thing just locked up. less than a mile on it, had been breaking it in justing running thru the rpm ranges slow increase, drop it down slow increase, sounded good.......... then a horrible sound from the engine..... damn, hope its something stupid not wasted, but if it is i will just junk that scooter, its been a problem any way. what? |

Your gonna have to keep an eye on her . since she wasn't getting any oil to the head or the crank bearings. She was def overheating , hopefully no damage was done. I'm not sure where the issue is, or the origin of this noise I described before, but I heard it less after getting oil to the top but I still hear it, usually in high RPMs. My tach broke a couple weeks ago (dropped it while carrying lots of parts and it broke into pieces) so I have no idea as far as a reading. I've decided to store it until a good like 70 degree day to strip down the head and see if there's any damage to the valves or cylinder. I still have my 50cc so I am just using that to get around for now. It's so nice to have 2 scoots now lol. |

 Yikes! but you do lead an oddly charmed life lately. I think some of us here are wondering what's next. I wonder how he found out that you know about scooters and how to fix them... word of mouth advertising perhaps? I hope things turn out so that you'll have happier stories to tell. The frustration you've been experiencing must be maddening.  My life is a series of unfortunate situations interrupted 2-3 times a year by something good. I am used to the world falling down around me, and people trying to screw me over, my life is the training for being a bouncer at a bar I would say, hah... I'm nice, but I can still be cold towards people and show them I mean business. I never start any issues myself though. |

Well the guy has not come back yet, I called him and he said he's too busy, so I told him he has until friday before I drop it off at the police station, and since I live 2 blocks away it's just a 5 minute push over there, not even.
Yes, my life has always been interesting. I like to fix things, I like to help people, but most other people just assume I am nothing and try to screw me over. I dress like a mechanic, all my clothes have oil stains, and about 5 days out of the week I AM working on scooters for myself or friends, but I do not work for people I do not know usually. The only reason I went ahead and started fixing it was I wanted to fix it, simple as that, I like fixing, and wanted to fix something, and at the time it was the only broken thing in my yard. I should have just left it there and when he came back told him to take his trash out of my yard, but I had already started tinkering with it. I am one of those people who just impulsively fixes things, I do not think about it until I have started unscrewing it.
Normally I only help people I know, I do what I can until I discover the parts are unsalvagable then talk to my friends and link them to the parts. It's a lot easier that way, I already trust these people, they know I'm not a pro, they offer to pay me for the work, I don't even ask, and we all have fun working together. I mean working with my friends on scooters and other projects is how I spend most of my time, and what I enjoy most.
This random guy is quite the opposite, he got pissed off when he found out he had to pay for the parts he asked me to order, then got even more pissed off when I told him he can't have his scooter till he pays for the parts. Then when I try to say he can have his scooter back for free, just let me remove the parts, that also made him upset... So it really seems he was aiming to screw me over, or he assumed I am running a charity where I give away my time, and empty out my wallet, so some dickhead can ride around on a scooter he probably stole.

So just in case anyone else ever has this question; Do you need to drain the oil to work on the pump? Answer is yes. No one here seemed to know, no manual said to remove the oil, just says open it and replace the pump.
I have oil going to the head now after replacing the pump.

well I don't see any oil. I know how to change the pump, or I think I do, based off the manual, but like I said before I would like to know if I have to drain the oil first, the manual does not say there is any oil in the area where the pump is.
I do not want to have to find out the hard way, I have enough auto spill spots on my pavement............
So do I need to drain the oil??

Thanks that helps a lot! Looking at my old jug I can see the shape you are talking about, and I think I may have found gasket pieces in the oil that may have come off the crescent shape because the gaskets seem to overlap into the crescent shape a bit nomattter how perfectly I place them. I am guessing my oil passage may be clogged with gaskt pieces. I remember finding gasket pieces in my oil a couple months ago but when I did not find anymore I thought it was okay. Did you test to see if the pump was working ? I doubt its clogged. If no oil is getting to the head , 9 times out of 10 the pump is bad. If you do the oil pump test , and find that is bad , let me know and I'll give you a run through on what to do to change it . How many turns of the flywheel should produce oil in the head? Like right away? |
