| Troublesome SU Carb. A DIY Most of the mechanical work are done as on date, inspite of slow progress, the only thing thats troubling us is the Original SU carb. Even the so called Experienced mechanic also is unable to fix the issue. So fed-up of the whole drama, i myself removed the Carb from the manifold today and have got it home. And....! What am i going to do with the SU carb........  I intend to use my acquired skills off-late and some search on the WWW., i am going to get this thing working. I sit and analyse the main issue, 1) When we start the car, the engine races well 2) It does not hold well at Idle Some pics of the Carb |

 Now what advise do you offer Pawan? None.Pawan, I want to share an experience with you, maybe you have a similar problem. Many have seen pics or heard about me and my green Amby being a daily driver. Well, a few moons ago, I had obtained a SU carb meant for the early Amby/Landmaster series with a suitable manifold. This ran well for a while, till my carb needed an overhaul. Try as we did, we could not get a proper kit with suitable needle and pin. This was not even available in UK. So finally I put back the original Carb and manifold. You can only try to get an original and good kit from UK. Otherwise, most likely you are doomed. Been there, done that, and hoping my experience will help you. Cheers harit | ||

Sir I think we should let him do it his way and if it doesn't work then there is always advice to give. So why not let a person try in the first instance ? | |

Dont get worked up Guys  I am on my Work.Dismantled the Carb, Found the needle float not floating as it actually should. On the high rev point, the Float is getting stuck on Top and at cold start, the needle is getting stuck at the bottom  Got a bit of Steelwool , mixed it with Glass wool (40-60%) and started shaving off the rough edges if there are. I might take it to the lathe and get them polished or Buff it. What Oil should i Use at the TOP? Presently have put a bit of Engine oil, i feel its wrong, it says USE THIN OIL EVERY MONTH | ||

| Thank you Manish Finally after 2 days of DIY found the real trouble maker. The Idle float needle is fabricated sometime back and its diameter is just a bit more than what it should be.  Taking this to the lathe tomorrow to get it polished a bit to loose some overall diameter. Hope this solves the trouble. |
