Using a screwdriver into the spark plug hole, turn the engine over manually by turning the primary clutch by hand. Measure movement in and out with the screwdriver till the piston is at “top dead center” or “TDC”. Use a.004 feeler gauge between the top of the valve stem and the rocker arm adjustment bolt head.

Do you need to tune a 2 stroke carburetor?
Why You Need to Tune Your 2-Stroke Carburetor. Improper carburetor tuning will have a much more significant effect on a 2-stroke engine than a 4-stroke because the premixed oil lubricates the crankshaft. A rich mixture will cause poor performance, but a lean mixture can destroy your engine (over time).

How do two stroke engines work?
1 is the displacement, they generally have smaller combustion chambers, which means less fuel burned. 2 is the fact that they have fewer moving parts , which decreases the constant load on the engine, allowing it to burn the air-fuel mixture more efficiently , and reach much higher revolutions per minute.#N#Here is the process of the engine.#N#Intake, The fuel/air mixture is first drawn into the crankcase by the vacuum created during the upward stroke of the piston. The illustrated engine features a poppet intake valve, however many engines use a rotary value incorporated into the crankshaft. During the downward stroke the poppet valve is forced closed by the increased crankcase pressure. The fuel mixture is then compressed in the crankcase during the remainder of the stroke.#N#Transfer/Exhaust. Toward the end of the stroke, the piston exposes the intake port, allowing the compressed fuel/air mixture in the crankcase to escape around the piston into the main cylinder. This expels the exhaust gasses out the exhaust port, usually located on the opposite side of the cylinder. Unfortunately, some of the fresh fuel mixture is usually expelled as well. I'm going to interrupt here for a second to explain how that fresh mixture is prevented from being expelled.#N#so, you think an exhaust pipe is just meant to get the exhaust away from the engine, right? well in the 4 stroke application that's completely true, but in the two stroke, you must use a specially formed pipe, that uses something called backpressure, to force the expelled mixture back into the combustion chamber, this can be seen in the animation quite clearly.#N#Compression. The piston then rises, driven by flywheel momentum, and compresses the fuel mixture, insuring that the mixture explodes properly. (At the same time, another intake stroke is happening beneath the piston).#N#Power. At the top of the stroke the spark plug ignites the fuel mixture. The burning fuel expands, driving the piston downward, to complete the cycle.
What happens if a two stroke motor is too lean?
Two stroke motors are VERY touchy in the tuning process, if they run too rich, they bog down and quit. if they are too lean, they will over-power themselves, and 90% of the time they explode violently. I'm not a certified mechanic in the least. but I do know what I am doing when it comes to re-building and tuning small engines, mainly two strokes.
Where is the fuel mixture compressed?
The fuel mixture is then compressed in the crankcase during the remainder of the stroke. Transfer/Exhaust. Toward the end of the stroke, the piston exposes the intake port, allowing the compressed fuel/air mixture in the crankcase to escape around the piston into the main cylinder.
How to tune carburetor air?
The simplest way to tune your carburetor air/fuel mixture is to look at your spark plug. If the plug is black with soot, the mixture is too rich. If the plug is white (burned), the mixture is too lean. You can also determine the air/fuel ratio based on the performance of your dirt bike.
Why is carburetor tuning important?
Why Proper Carb Tuning Is Critical For 2-Stroke Engines. Improper 2-stroke carburetor tuning will have a much more significant effect on a 2-stroke engine than a 4-stroke because the premixed oil lubricates the crankshaft. A rich mixture will cause poor performance, but a lean mixture can destroy your engine (over time).
What is the main jet on a jet engine?
The main jet is numbered and is interchangeable with jets that will provide a leaner or richer air-fuel mixture. Replacing the existing jet with a higher numbered jet will make the mixture richer, while jets with a smaller number will make the mixture leaner.
How does a jet needle work?
The jet needle regulates fuel by its taper, diameter, and clip position. In the closed throttle position, the tapered needle shuts off flow from the needle jet. As the throttle is opened, the needle allows fuel to pass by the taper and between the straight portion of the needle and jet wall.
What is the body of a carburetor?
Carburetor Body. Body – The carburetor body houses all the moving parts and jets, and mixes the air and fuel on its way to the cylinder. Bowl – The carburetor bowl is located on the bottom of the carb and holds the fuel to be sent through the jets. The bowl also houses the float assembly. 2-Stroke Carb Body And Bowl.
How to adjust needle in jet?
The position of the needle in the jet can be adjusted by removing the needle clip and positioning it on a higher or lower groove in the needle. Raising the clip will lower the needle into the jet, creating a lean mixture; lowering the clip will raise the needle, creating a rich condition. Jet Needle Adjustment Clip.
How does a slow jet work?
The slow jet draws fuel from the bowl and mixes it with air from the pilot air jet passage. The atomized air/fuel mixture then passes into the throat of the carburetor.
