Initial needle settings 91 4 stroke
 

I have a Thunder tiger 91 4 stroke that hasnt been ran for some time. When I put it away a couple years ago it ran great.

Can you tell me the starting point fo rhte needle valve, I cannot get the thing to run now.

I did get it to run once but as soon as the glow driver was removed it died instantly.

Thanks

High-speed needle about 2-3 turns out from closed as a starting point. Idle needle at about 1/2 of its full in/out range.

Thanks Bax,

My be a dumb question, but just to make sure on the low needle you mean half of its distance between fully in and fully out (unscrewed)?

Thanks again.
