Thanks for all the help it's great! Yes this was a great find Mowerfreak, it almost feels like a new mower. This find was a lucky one I don't think I will find one again in such great condition.
I did test the needle and float just by hand before I installed it and the needle was going up and down fine when it was dry. The only thing I am thinking is there was a couple of little bits of plastic moulding edges hanging on the end of the hinge on the float. I just used some small pliers to clean it away a little bit but I didn't clean it up properly. Just maybe the float hinge could be slightly sticking to the plastic rod on the primer cap? I might have to take the cap off and make sure the hinges on the float are completely free of any plastic bits where it sits on the hinge.
It only started doing this when the engine was hot after running for over 30 minutes or so. First I will try cleaning the hinges on the float of any plastic moulding edges to see if it makes any difference. If it's the same then I will try the original faded Victa needle and float that were in this carby to see if it runs better with them.
Cheers!
