Scooters still running well. Managed a 130 mile round trip to St Georges run in Cambridge without any problems even two up. One issue I have is that when filling gearbox oil I can only seem to squirt 200ml in using a syringe. I've seen videos where they are tilting the scoot to get more in, is this advisable ?

More good news. Scooter passed its MOT this morning and been riding about most of the day without any problems. Thinking of chancing a run out to Oddballs Rally in Oxfordshire tomorrow. I tried to read the numbers off the old jets from the 20/20 carb but the old eyes ain't what they used to be.only slight issue is a very intermittent jerk from what seems to be the clutch when riding at the top end, only lasts a second so I'll keep plugging on. ?

Potential success, fitted a new spaco 20/17 carb this evening and bingo. Scooter runs perfect, rode it around the block and it never missed a beat. I did notice that the carb fitted to the scooter was a 20/20 D Dellorto so hopefully that was the problem. I'll keep you posted after a longer run and maybe an mot. Thanks to everyone for their input.

What's your views on a new carb. The one on it could be make up from a box of old bits ?

Tonight I fitted a new plug, scooter started first time, revved up good and ticked over fine. I left it ticking over for about ten mins and occasionally revved it up. All was good. Switched it off and re started it and instantly turned to sh*t. As soon as I touched the throttle it bogged down and died then started ok but would not rev up. I removed the spark plug and found a slight stickyish oil on it. Not thick oil. I was thinking of getting a new spaco 20/17 carb and starting again. I don't have much time to spend on it during the week so I can't check the oil for fuel smell but will do on Saturday. I'm assuming it has electronic ignition because I cannot see a hole in the flywheel which looks pretty new. I'm pretty new to two stroke Vespa's so I'm sorry if I'm asking stupid questions. As for checking the timing I'm guessing that would involve removing the flywheel and special tools etc.

Removed the carb again a renewed the base gasket. Checked the oil, all ok, checked the plug, wet but not that oily. Scooter produces a good spark, not really sure about the timing as I don't have the tools or even sure what ignition system it has. I think the carb is knackered. I've tried adjusting the mixture screw for hour and it seems to work at first then soon returns to bogging down when you open the throttle. I can't ride it so I'm not sure about top end running. It's really frustrating as it was almost running ok three days ago.

Do you mean that the side panel handle is vibrating loose from the lug on the side panel because it seems that the lug is too short to locate the handle correctly on the side panel. Apart from running issues (see my other post) my 150 does the same thing when I'm riding or reving the engine.

Going by the engine number it looks like the original unit. I have never had it running as it should since buying it. It's been totally restored by the previous owner so I'm not sure what has been done to it. It was running about 85% good until I resealled the carb and air box. When I say 85% I mean that it was rideable now it will not go over 100 yards without bogging down. I'm going to have another go tomorrow weather permitting.

I now have the scooter running too rich, on plug check the plug is wet and oily. Adjusting the mixture has little or no effect. The scooter ticks over and starts fine then after a few mins when opening the throttle it just bogs down and eventually dies.

Re sealed carb and air box, thought it was ok. Revs now dropping when screwing in mixture screw. I left to ticking over for five mins and tried to to take it out. As soon as I opened the throttle it bogged down and cut out, it started up ok and ticked over but died when opening the throttle. It will only rev up if I hold the choke on.. I can't even ride it now as it won't even pull away.
Help

Back again.
Checked out the choke, all ok. Adjusted the plug gap and air screw and road tested. The scooter went ok but still has a misfire low to mid range revs. When screwing the air screw all the way in the scooters revs rise at tick over but missfires even worse. I have the air screw 3/4 of a turn out at the moment And it runs about 85% perfect. I'm thinking of refitting the carb with a new gasket in case there is a leak. Any ideas ??

I'll check the choke, never thought of that. The Scooter has electronic ignition fitted, all the connections checked out ok. Thanks for your help. I thought I had it fixed earlier today then it cut out after riding for about 10 mins ?

Help Purchased a Vespa 150 Last year and seem to be having a problem with cutting out. The Scooter starts first kick every time but dies after riding for a few mins. I have shortened the fuel hose and cleaned out all the filters (carb and Fuel tap). Cleaned out the carb and put in a new spark plug but the problem still persists. I thought it might be fuel starvation as once it cuts out it starts up after about 30 seconds but runs bad. I have tried to adjust the mixture screw but to be honest it does not seem to make much difference. Any idea's
