Needle circlip on late model Amal

[Buzzook]

Hi all

I was taking the throttle cable off the late model Amal on my ESC to see if I could free it as it had jammed, and in the process I somehow knocked the circlip that holds the needle in the base of the carb slide off.....

...and it has three grooves in the needle stem to choose from........eeny meeny miney mo.....

Anyone know which it should be for standard 25:1 set-up?

This is the single body Amal with the black plastic float chamber....

And it's a Model 75 Silver Century ESC

Ok, I slotted it into the bottom slot and after I changed the plug and added new fuel, it fored on the thrid pull.

Then I found it was nto piumping any water at all - despite me having drilled out the crap that was blocking the head....

So am now pulling it down to investigate further.

Sorry Mark I was waiting for someone else to reply.

In the factory these were fitted in the middle groove during assembly, during it's test tank run it might well have been moved up one if running rich or down one if running weak.

Remove powerhead & then exhaust tube & then water delivery tube, check tube is clear from top to bottom, check around exhaust port for signs of cracking, check that there is a clear passage from the water delivery pipe to the water jacket.

Yes, the one Jim tried and then I tried after the 102 overheated.

Having pulled it down again and done some more backflushing it ran fine and pumped heaps of water, as seen on the video on the Bobbin Hd thread....

Will experiment with the needle setting as it seems to be running ok on the lower setting, except it is a little hard to shut off...
