Hello all,

I'm having some real misfire/ stuttering issues when I accelerate. Once i get up to speed, it feels fine, it's just at low revs. sometimes theres a hint of a backfire

Ive replaced plugs, leads, distributor cap, rotor, checked for vacuum leaks.

I think it must be something to do with the carbs (although I'm open to other suggestions) I have replaced the diaphragms which were split and distorted.

Is anyone able to upload a picture of a set of twin stromberg 150 on a 900? Im sure I'm missing a bit from the side of one of my carbs, I'm not even sure what it's called. Its like a long piece of housing with a plastic top on it. I've attached a picture that I've just pulled from google, and circled the part I mean. What is it? and I'm guessing I should have it on both my carbs?

Any help would be greatly appreciated, I'm tearing my hair out!

So, I now know they're temperature compensators. Would missing one of these cause the problems Ive described?
