Help me fix my SU's!!!

[gator]

I have had the same problem as described in the firsts post. I thought my problem was float level. My mechanic sets the floats by blowing into the float jet (when remover from car) and closing the float as you blow. He sets the float so that it is just past level with the float lid (closer to it) as that is when it is shuting off the valve. This seems to work too.

My problem however is that I have been testing the car with no air cleaner on it and it hase been backfiring when warm with the choke off and stops backfiring and runs pretty good when the choke is pulled abit. I have re-installed the air cleaner and will test it in the morning (my eyes are closing at this time of night). It is cold here now and I think the cold air could be my problem.

I guess I will see.

I purschased the Z-theraphy tape to help me with my carb problems,and he says that measurement should be set @ .55"

If you measure from the float cover to the top of the float, it should be 14-15 mm (which is close to .55"). If you measure the actual fuel level in the bowl, it should be 23 mm from the top of the bowl. The fuel level can only be measured with a sight tube and the fuel pump running.
