Opinion on this Break In Procedure?
Hi Guys,
I got this info from a friend, please comment.
BREAK IN PROCEDURE
Some things to remember during break-in
1.Run with the body off.This will keep the engine cooler.
2.Keeo the air cleaner on at ALL times.
3.Run on a smooth,hard surface.An empty parking lot is perfect.
4.Use the same fuel that you will use for normal running.
5.Resist the urge to accelerate and decelerate quickly.
6.Break-in puts stress on the glow plug and can burn it out.Make sure you have an extra plug or two on hand.
7.Do NOT overheat the engine.
TANK 1
Your first tank of fuel should be running the car at a very rich needle valve setting.This allows the fuel to carry as much oil as possible into the engine to properly lubricate the internal parts during the break-in.
1.Open the high speed needle valve 4-1/2 turns from fully closed(counterclockwise).This is factouy set already,but check it to make sure.When closing the high-speed needle,close until youfeel some resistance.DO NOT overtighten or you will damage the engine.
2.Fill the fuel tank and start the engine.
3.Run the buggy on a smooth surface with the body off.
4.Run back and forth at medium speeds,slowly accelerating and decelerating the buggy.
5.Run the buggy until the tank is almost out of fuel.Do not allow the tank to run out of fuel during break-in.This leans out the engine and can cause overheating.
6.Stop the engine and allow it to cool.This noumally takes around 10-15 minutes.
NOTE:If your engine does not stay running consistently,increase the idle speed by turning the idle stop screw clockwise.
TANK 2
Lean the high-speed needle 1/12 turn from "tank 1" setting.Run the buggy for the complete tank and then let cool.
TANK 3
Lean the high-speed needle another 1/12 turn from "tank 2" setting.Run the buggy for the complete tank and then let cool.
TANK 4
Lean the high-speed needle another 1/12 turn from "tank 3" setting.Run the buggy for the complete tank and then let cool.You should notice the engine running much better at this point.
TANK 5
Lean the high-speed needle another 1/12 turn from "tank 4" setting.Run the buggy for the complete tank and then let cool.The engine is now ready to be perfoumanced tuned.
Important! At this point,the engine will likely be running at a faster idle speed than needed (This is typical after break-in).Adjust the idle stop screw to lower the idle speed so that the wheels do not ,or just barely,rotate when you lift the buggy off
