The ST G90 likes to have the ''it's own way''.
<ul>[*]The G90 likes LOW nitro percentages - many happy owners recommend 0% or 5% and will argue to the death. Diehards for sure.[*]The needle's cat's eye needs to be aligned with the throat of the carb. see pic 1.[*]Have a spare throttle linkage because they are CHEAP.[/list]There a MANY happy G90 owners out there.

Get a couple of #4's - if you have a spare you'll never need it. Just like the guys who take a 30 gal. trash bag to the field to ensure that they will NEVER need it. How UNTRUE that is. [img][/img] My LT-40 didn't need the bag but it needs repair - bad battery pack.
For more info check the Glow Engine forum - might even be a Super Tigre sub-forum. Check it out.
This is not only true of the G90..........liking LOW nitro percentages. I was recently having problems with a well broken in OS91FX and I had to do a factory mod to help it along but the suggestion was there that when you are approaching bigger engines like the 90's/91's they do like a lower percentage of nitro. I have since gone to 10% from 15% and the 91 runs much better and is much more reliable. I do have a ST75 that I had been running 15% in but I'm also going to go to 10% with it too.
