Ive finally got my 1275 running due to timing issues. Although ive got a carb that was tuned for a 1380 engine. I need to change the needle.

At the moment it won't run without choke, and doesn't run well at all.

The needle at the moment is quite thick, would making it thinner make it run better?

I would much rather just put a needle in it though than mess around with it, what needle would you recomend for a 1275, HIF44 and stage one kit.

BDL or BDR

Brilliant thanks alot. I will sort one of those out as soon as possible, Is there anything I can do to get it running better for now, because I want to get an MOT before wednesday.

BDL or BDR

Mini spares sais the BDL should be used with a 256 degree duration camshaft with standrad filter. Thats not my setup.

playing with winsu gives O?7 as the best result, but I dont have the full version so i can't work out the last letter :/

had another fiddle, managed to find out it's a OA7. Only quickly checked it out but that gave the best results overall, 0.6% rich throughout, as opposed to 4+% on anything esle.

Hope that helps.

Ummm it might help if I knew what those numbers meant, doesnt come up on mini spares.

Ok im stuck, I can't get it running nice. I put a carb on from my 998 and it took ages to get running once it did it was rough as anything and kept spitting back throught the carb mouth. Not going to use that carb then.

It drove on the hif44 but needs choke to idle, what do I need to do to the needle to make it idle? shave off the point or nearer the top by the spring. I want to take this car for an MOT tomorrow.

Eeeek I'm not sure about profiling needles, try a PM to dklawson? He did a thread a little while ago about profiling needles I think, I'm sure it was him.

As for the OA7 needle, you'd have to do a google, or try www.burlen.co.uk

HTH.

Well thank you who have helped. Ive now got it going quite well, I think itll be enough for mr MOT man. 1000 rpm idle and revs very freely. Hopefully its enough,Idealy I need to get it on a CO2 meter but I cant afford one. I got the needle from a scrap carb I found in a friends garage.
I think its a standard 1275 needle, but who knows.

Will one of those needles work?

It's an SPI engine, running a HIF44 carb, foam air filter, lcb exhaust system. Slightly bigger valves.

Pretty much a stage one 1275 engine.

Minispares stage 1 kit for a 1275 with HIF44 carb comes with a BBW needle

You can tell which needle you have because at the thick end it will be stamped on the side.
