G'day David,
I have a 23 McLaughlin with a K model carby. I just found this discussion. I am having troubles with mine. It appears to go through fuel so quickly, that the float doesn't have time to come up and close. It runs like a donkey until I manually shut the needle on the float. As soon as I do this it runs sweetly until it the requires me to let the float go and allow some fuel in. Any ideas?
Also, did you find a replacement carby that was reliable ?
Thanks,Richard.
