What needles for this set up ?

[youngcamper]

Hi All,

I'm currently trying to sort out the rough running on my car. It's got standard 1098 engine with 1 1/4 twin SU carbs with pancake air filters and a 12G206 head.

I haven't fitted any of this so I don't know if the correct needles are fitted in the Carbs. Does anyone know ?

Cheers,

Will

Is this the Spridget engine with the burned exhaust valve ??? What needles are in there just now? I believe M is popular.....

Thats right, I thought that thread would get too muddled if I asked this. I am pretty sure M is what it has but I will check.

Thanks,

Will

1962 - 3 1098 Midget engines used GY needles, M was the rich option.
1964 1098 Midget engines used AN needles, H6 was the rich option
This set up was also used on the 1275 Midget

thanks Mike,

The needles were the right ones after all, a quick go with he colour tune had it running really well.
