Hi!
Goirish! Why did you remove the low speed needle when you removed the throttle arm?

First picture shows a Kyosho GX.40 (same as a ASP .40 ll). Throttle arm is secured with a small (around 1mm in diameter) Allen head bolt.
Second picture shows the cylinder liner and its exhaust opening(s) on the same engine. All engines look more or less the same. Line up the exhaust opening on the cylinder liner with the crankase opening and that's it!
