shimming needles

[scottsgs]

Hi all,

I need some advice. I went to Radioshack and bought some washers and shimmed my needles. It's like night and day in the way it goes now. My question is this; I used one shim per needle. Should I have removed the plastic spacer on top? It only raised it what seems like a millimeter or less. Will the one spacer be enough?

Thanks,
Scott

I don't understand your question. Where did you place the Radio Shack washer?

The way to raise the needles is by removing the plastic spacer above the clip and replace it with a washer stack that is thinner - two washers typically is about right. Since the spring pushes up, the needle height is determined but the stack above the clip.

The idea is to replace the plastic spacer with washers. You want more needle sticking out of the end than before. The spring will push it into the plastic piece that goes under the circlip and raise the needle.

I want to learn how to do this and the theory behind it...Can someone put together some instuctions with pics(lots of them)? or get me a link?

Get the assorted Radio Shack small washers.
Take off the plastic spacer on top of the jet needle.
Stack washers to match the same heigth of the spacer. Remove two washers to raise the needle one notch. (like a dynojet needle or non-USA needles) Replace the plastic washer with this amount of washers.
This will raise the needle so it will rise out of the needle jet sooner and richen the needle circuit.
