I've been trying and I've got it pretty good but i will try to adjust it again tommorow and will let you know more ill watch the video thank you i will see if that helps a little
If the car is older than the engine ,then there is other things that may cause the issue that you described!
1. Make sure that the fuel tank holds tank pressure via from exhaust tube!
Make sure that the fuel tank cap has a good seal an does not leak!
That will cause the engine to run lean ,rev up an run unstable!
2. Make sure that the tank pressure tube is not plugged up from the muffler nipple or
if the tube simply slides in a hole in the muffler ,if it does ,pull the tube out an cut it at an angle
so it doesn't bottom out inside the muffler!
3.Make sure that your transmitters throttle trim is adjusted right in relation to the idle gap on carb
an not closing the carb completely off when you release the trigger/ refer to correct idle gap!
4. Make sure that you have a throttle return spring on the carbs throttle arm or lever!
Some people use a rubber band or a small metal return spring!
5. Check air leaks at the carb needles/most common when engines are old ,but needle o-rings
have been known to be bad new from factory!
I use sticky grease on old needle o-rings to help seal them!
I hope this info helps!..
