Hi all
I am running an o.s. 28 xz in my losi 8ight-t 2.0. With 30% nitro fuel. My problem is the I have the tune so rich that the performance of the motor is suffering ( bogging down out of corners and of the line ect. ) yet my motor seams to still get extremely hot + 140 c. I've taken the motor apart and every thing looks fine. There's no pre detonation signs on the pistons or glow plug. Will adding a extra head shim make it run cooler? Anyone got any other ideas why it might be running so hot? I've even cut the windows out on my shell so it's not a air flow issue.
