Hi Paul,

Assuming you are referring to the float chamber, you need to check:

1. That the locking screw on the top has been loosened
2. That the float needle is engaged in the hole in the underside of the lid, and
3. The lid is not on cross-threaded.

The important thing is not to use force - just nip it up and tighten the lock-screw.

I hope that helps!

Unfortunately, this is not something we stock - we probably should, but there are so many things we are trying to do at present. If you feel inclined to get a batch made - 20 perhaps - we would happily buy the surplus from you (provided the price is not sky-high!). If you are happy to do this, let me know, and I will send you a drawing.

OK Thank you
Is there any information out there about fitting inverted levers? What holds them into the bars and do I need to buy new cables? Thanks John

When trying two look at the new and used items for sale, it asks for a user name? Which I cannot remember  or find? Can you help with this?.
