the instructions for the turmoil .26 motor say fill the tank start the motor and drop it on the ground and run it with much smoke coming out of the pipe to ensure the motor is running very rich ..run 3 tanks this way and your motor is now broken in and ready to be leaned out .....lolololol...what they dont tell you is that this will cause the internal parts to not expand and contract enough to break the internal parts in ...many manufacturers just use a generic break in procedure because they dont want to confuse new drivers and complicate things ...the best break in procedure is from the late ron paris ...who was arguably the best nitro motor tuner in rc .....
start car on bench with aluminum foil wrapped on the head
once car is running lean the top end needle until the head temp reaches 220-240 degrees
shut the vehicle off and bring piston to bdc
let cool to ambient temp
repeat 3 more times
then throw vehicle down and run it keeping temps at 220-240 ...
run 1 tank 1/4 throttle blips ...then one at 1/2 blips then one at 3/4 blips the one at full throttle blips ....never blip throttle for more than 1 second at a time ...run whole tanks and let cool to ambient temp in between each tank
it will take you all day but you will have a motor that is good and heat cycled ...which inmho id the most important thing.....just all my .02 worth
