high speed needle assembly question
 

I'm wondering if I may have found the reason for my poor running TTPro .36.

Where the HSN screws into the carb. there will be a washer then a nipple that the fuel line attaches to.
Underneath this nipple a hole is drilled through the main shaft of the HSN.
When the HSN assembly is attached to the carb should I make sure the nipple ligns up with this hole?
It looks like the assembly could be tightened up with the nipple rotated on the shaft so it does NOT line up with the hole under it.

If I had done this could it cause a problem?



I have not been able to get onto the web site to look at a manual / assembly.

can you post a picture ?I can not tell by your description where this hole is .

It shouldn't make any difference, because (providing everything is machined/manufactured properly ) there should be an annular groove all the way around the inside (that piece w/ the fuel inlet nipple is known as a "Banjo fitting" ) so as to feed fuel no matter what the orientation of the fuel nipple is.

This is what I was thinking but was hoping it would fix a problem..

the term here is properly machined.There have been instance where the nipple is not drilled out properly or attcheched properly
