I recently rebuilt a Holley NH and installed it on my 15 touring today. Starting seems much easier with less flooding than the old L4 that was on there. May run a little smoother too ... overall I like it.
Ran into a few small problems though:
1. the spray needle is ever so slightly bent. Not on the needle itself but the brass shaft just above the needle clamp nut. The only problem this causes is as you rotate the needle the force required varies with the rotation of the needle. Makes it somewhat difficult to adjust (smoothly). Is there a good technique to straighten that bend or just buy a new needle ?
2. The carb adjusting rod that comes through the dash worked fine on the L4. On the NH the fork can slide too far down into the needle crosspiece and the securing cotter pin binds on the needle clamp nut. If it does bind you can't do any adjustments until you pull the rod up. Any way to fix this ?
Thanks in advance ...
1. Body work. Rap it straight with a small hammer.
2. Shorten the long side of the fork and drill the opposite side?
2. Remember to pull it up every time. I had to do that on my '15. After a while it becomes a matter of habit.
