I'm starting to run this engine and was looking for opinions on the low end needle. Are any of you using the low end needle? Or Just cutting it off and screwing it in?

Thoughts and opinions please.

Thanks in advance.
 
cut it off it cost me a race by not cutting it off as it vibrated back in and could not run up to speed during a race
 
Walt,
These are very smooth running motors and you should not have that much vibration to move the needle. Check the run out on the collet. That is where most vibration comes from.
