RE: setting idle and fuel mixture
O.K...good to hear we got things headed in the right direction...
Now....you say the wheels still turn slowly?...is this while it is on the bench with no weight on the wheels? or does the car move when sitting on the ground?....there is no problem if the car seems to want to move when you put it on the ground...as long as it doesn't take off and just "acts" like it wants to start moving...
Go ahead and turn the the low speed mixture screw in a bit at a time until it is idling decent..give the throttle a "blip" or two and see how responsive it is....as you lean down (turn in) the low speed screw the idle will more than likely pick up a bit..(this is normal as 2-strokes idle faster than 4-strokes)...if the car wants to take off after that then you can adjust the idle speed screw accordingly to keep it from taking off...if it tends to "lurch" a tad bit while it is sitting on the ground...thats no problem..
Make SMALL adjustments at a time...no more than 1/16-1/8 turns at any one time on any of the mixture screws (even LESS on the idle speed screw) and after each adjustment....give the motor a little time to adjust to the new settings...the changes will not be immediate...also...don't try to make too many adjustments to the idle and such using the controller....leave everything zeroed for now then you can make a few fine adjustments after that if needed..
Just keep in mind that tuning these things takes a LOT of patience and very fine adjustments...if you are patient and keep making these minor adjustments she should come around to you.
Let us know how it goes!
