New carb socket fits loose

Hi Kelsie,

Have you swapped the "Carburettor Socket Assembly"  (CSA) from one side to the other?

If so, did the tight fit, move with the swop?

# If it did it's definitely the CSA.

# If it didnt, it's the carburettor itself (ie not the CSA).

I did not swap the socket, because it is loctited in place and I don't really want to mess with what isn't broken. But I did swap the carbs just to see how the 1/3 would fit in the 2/4 socket, and it was loose there. So it does seem to be the socket. 

I called Lockwood yesterday, and they test fit a new socket for me, said it was so tight they couldn't turn it by hand on one of their carbs, and then sent it to me. So I think my immediate problem is about to be solved. However, I do think there is a manufacturing problem here, and I've been asked to file a report with Rotax about it. I'm going to be taking some video of the problem for Rotax, per Lockwood's request.

Kelsie,

I just inserted my five year refreshed carbs into new sockets from Lockwood and both sides had a distinct click upon insertion and both are nice and snug. 

Thanks for the followup, Jim!

I also received a new carb socket from Lockwood, one which they tested before sending it to me, and I still have the same issue once it is installed on the engine. I'm at a loss currently as to what might be causing this, but I no longer think it is the socket itself.

Well that is odd- it will be interesting to see how your engine idles and how your pneumatic synchronization goes- if the loose socket leaks air it will cause problems.
