Needle Settings For A Walbro 644
Hi, i know what the manual says are good settings on a Walbro 644. But i was just wondering what the best settings you guys have come up with on a stock Zen 260 with the 644?? Im using a NGK plug.

RE: Needle Settings For A Walbro 644
if i remember correctly the 'final' settings i had on my 644 with stock motor was like 2 on low and just under 1 on high. Needle settings will vary depending on air conditions, elevation, etc.
