carb take 2

Thu May 14 21:48:19 PDT 2009

The DJ kit came with a 5/32 drill bit, but this is a large bit and used to make a pilot hole to pull those plugs out.

I know I have a lot of questions, but this is my first time doing a jet kit. I am just soaking the carbs overnight and reassembling tomorrow.

DJ supplies 4 clips and 8 washers. Per their instructions, I'm putting the clip on the second from the top groove with 2 washers over it.

Then I put the needle in the rubber cup.

Then the white cup thing with the feet over it goes over the end of the needle.

Once it is all together it seems as if there is a bit too much free play in the needle. Is this ok?

Regards-
