One of the throttle levers for the second engine is a little loose when push it up wants to fall back on its own i took the assemble out and the nut is tight holding the throttle cable assembly but seems to still have some slack to it anyone know how I tighten that up just a pinch at idle position there is some slack in the cable looks like need to tighten up the throttle cable
just go slow and dont stay in one spot too long with the gun its better to come back at it for a second run with the gun and do it outside not in the garage so you not breathing in the plastic fume is really easy just keep gun like maybe 3 inch away from plastic is what I did. The gun i used had 5 heat setting i was using #4 pretty hot so didnt take very long did 2 passes.
