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.
