Firstly that main jet seems a little on the large size if the sizes are the same as Delortto then i would say you need to drop down to around 118-120, secondly SI carbs or spaco as they are better known in my experiance are of poor quality and notorious for being hard to set up. persoanlly i would bin the thing and get a proper delortto 24/24 carb it wont cost the earth and will save you hours of mucking about.

SI 24/24E IS a standard P2 carb whether it be Dellorto OR Spaco, and there's no difference between the two, the Spaco is no harder to set up than the Delly as it's the same carb made under license.
The 160 is your air corrector, not the main jet.
If you unscrew the air corrector you will find the atomiser/emulsifier tube, and below that you'll find the main jet.
Your atomiser should be a BE3 and you need to be running about a 120/122 depending on whether your scoot is autolube or not.

Turn your petrol off when you stop!
No seriously, turn your fuel off, allow it to tick over for 20 seconds or so and then switch off your ignition. 1 it means that it shouldn't be flooded when you next go to start her up, 2 your float needle isn't continuously immersed in fuel so it's life is prolonged.
next time you go to start her up just choke on, wait til she starts and then fuel on. Make it a habit and you'll notice the difference.

The bowl is part of the carb body fella, it doesn't come separate.
It's either a whole new carb or live with what you got I'm afraid.

If the needle is new and the float is good, then maybe its worth to clean the needle house (where the needle goes in). there can be a tiny thing stuck on it, enough to allow fuel to enter pass the needle.
What Ive done is take an ear bud with a little rubbing compound on it, put it on a cordless drill. A few seconds of cleaning will do. If you use rubbing compound, make sure to clean the carb thoroughly.

Well, you have to do it with the carb removed from the engine.
The cleaner comes in spray cans. Its very strong material so watch your eyes and avoid skin contact.
You would just have to open the float bowl, remove needle and float. Clean the needle house, then spray the area with carb cleaner.

Read more: vespa.proboards.com/index.cgi?board=general&action=display&thread=2498#ixzz1IxvR6Lq4Sorry but have to disagree with the above, Spaco are cheap poor made copies of proper Delorto carbs, the alli used is thinner and the threads strip very easily, the quality is very poor and any proffessional will tell you they can be a git to set up right. |

My First tip is bin the carb, its is clearly flooding and sounds like you have tried all the normal tricks, when you say all electrics have gone how far do you mean, does the electric start and horn work.

Check your wires to voltage regulator under left hand side panel.Check wires in black plastic junction box on top of engine behind carb.

Sorry Dave, I'd have to disagree with you on this one, as would the good old chaps at Piaggio as they were fitting Spaco SI carbs as OEM on the later P ranges. As I said they are made under Dellorto license, not just far east copies. As for setting up...... 20/20, 24/24 are set up exactly as they should be, the only one I know of that's a bitch to get right is the 26mm. Of course I will bow to vastly superior knowledge should anyone know anything different. |

Agree with you Joey.Your correct in saying that on the later model Vespas Spaco carbs were fitted as standard equipment.The replacement ones i have found to be excellent and very good value at around £45.I have fitted T5 and PX200 and they are set up perfectly.

Well speaking from current experiances as I have just had major trouble with a 24mm spaco standard fitted to a PK 125 LML , its a nightmare no one including me can get it to run right and its the carb changed it for a 19/19E delorto and its perfect, on examination it is clear that the carb is poor quality. I have spoken to a few people locally who rebuild scooters all the time imcluding a local dealers scooter mechanic and he agrees with me. He has attempted on more than one occasion to fit those 26mm spaco carbs you see on ebay that people have bought and he has never managed to get pone to run right for any length of time. At the end of the day I believe in the old saying you get what you pay for, I just paid £90.00 for a genuine 19/19e BNIB its two thirds the size of the standard 24mm spaco but 3 time the weight?  Good luck chaps |
