Hi Guys well I called acehobbys and talk to the service dep and they told me to set the low speed neddle .32 to .16 of a inch so I got a feeling gauge and tryed it and it worked the only thing was it was a little too much so I went down to .010 and it worked out good it started right up and idle good I took that measument from another carb from a TT36 Not saying that the 2 figures they gave me were wrong it was a good starting point . And for all you out there that have a problem with your ThunderTiger engines dont be afraid to call ACEHOBBY They are Great and VERY VERY Helpfull you can reach Them at AceHobby 1-949-833-7498 ask for John he is really good and very Friendly. Anyway so far the heli is Idle good will try to fly it sometime tomorrow I have to reajust the high speed neddle. I will reort back to how it runs. Keep'em Flying Ed
