Have you tried the new Drafts feature yet? I just lost a long message today and learned my lesson. It is a good idea to save a draft of any long post you are writing. You can then just keep writing and keep saving a draft, knowing you have a backup if there is a glitch. The draft is automatically deleted when you post the message.

Amac Float

I have a 15 MDX carburettor (top feed) where the tickler doesn't reach the float to move it.

Could someone please let me know the correct float and needle dimensions for the 15 MDX. The float and needle if have fits well but something is not right. Also the tickler is of a good length.

The needle I have is 32. 6 mm long, with 22.2 mm above the float when seated. The float is approximately 41.5 mm dia and 38.3 mm tall.

Hi Rob,

One look at your photo and I thought "That's the wrong float" - but just the on-going mobile phone photo distortion problem.

Your float is the correct dimensions - used in both top and bottom feed. And the shut-off needle looks OK. SO perhaps it's just a case of extending the tickler a little? A plastic cap on the end would work.



Thanks Leon,

I think that would be a good simple solution. Seeing that the tickler looks correct and quite long I just thought the needle was wrong.
