Adjust the valve on top of the throttle body with a 1/4 turn in the inward direction. Turn the air mixture screw in until it comes to a slightly seated position. Turn the screw outwards by 1-1/2 turns. Push the throttle stop screw backward until the throttle shaft is closed completely.
How do you adjust the valves?
You adjust one valve at a time, by turning the clutch until the valve you are NOT adjusting is at max lift. You might need to do this several times because tightening the jam nut will alter the adjustment. Turn the engine over to TDC and recheck the settings.
What kind of engine does a Yamaha golf cart have?
Initially, the Yamaha G1 2-cycle gas was the standard-bearer and in 1985 the G2 4-cycle single-cylinder gas engine was introduced as the new standard. link to How Does A Golf Cart Work? - Complete Guide To Understanding It (2021)
What is the difference between a golf cart and a car?
Golf carts are also known as golf cars. The term "cart", in its purest sense, refers to a vehicle that does not travel under its own power. Golf cars, however, are most commonly referred to as golf...
What is the correct valve clearance?
Recommended valve-to-piston clearance is generally 0.080-inch minimum on the intake side and 0.100-inch minimum for the exhaust valve. The exhaust needs a little more clearance because it expands more with heat.
Do you set valves hot or cold?
Major camshaft manufacturers recommend setting valves cold, to avoid erroneous adjustments on lifters that may be "pumped up" If you are setting valves on a fresh engine that has not been run, everything should be well lubricated before you begin.

Do valves get tighter or looser when hot?
For an engine with cast-iron heads and steel valves, you can expect the lash to tighten up a couple of thousandths of an inch as it heats up-so for the cold lash you would set the valve lash a couple thousandths larger than the cam manufacturer's recommended hot lash setting.
How do you set valves?
When the exhaust valve just begins to open on the first cylinder in the firing order, adjust the intake valve by loosening the adjusting nut slightly while spinning the pushrod until you feel lash in the rocker arm. Tighten the adjusting nut until the slack is taken out of the rocker arm and pushrod.
How do I stop my golf cart from backfiring?
One of the simplest ways to reduce backfiring while operating a golf cart is to adjust the throttle plate so the controller does not apply fuel when the motor is idle. This makes it more difficult for residual pressure to build inside of the manifold and cause backfiring.
What engine is in a Yamaha golf cart?
At 357cc and 11.4 horsepower, it is Yamaha's most fuel-efficient carburetor engine. The PowerTech AC enables muscular hill climbing and a smooth ride. At 48 volts, its output is 5.0kw (6.7hp) for up to 60 minutes before recharging.
How much compression should a Yamaha golf cart have?
How Much Compression Should your Golf Cart Have? You can get a good feel about your engine's condition by checking its compression. The vast majority of gas engines should have a compression of about 150 psi. If your golf engine is new then your compression should be between 150psi – 160psi.
What happens if valves are not adjusted?
Too much or too little valve clearance can result in poor performance or a rough idle because the engine can't “breathe” normally and operate at peak efficiency. Too much clearance means the valves will likely clatter and, over the long term, cause damage to the valves, camshaft lobes or rocker arms.
What is the valve clearance for the intake and exhaust valves?
Opinions may vary between piston and valve manufacturers, but a popular consensus is a minimum clearance of . 080-inch for the intake and . 100-inch for the exhaust. The exhaust valve expands more due to heat from combustion, and therefore needs additional clearance.
How do you adjust intake and exhaust valves?
To perform the procedure rotate the engine by hand, as soon as you see the exhaust valve begin to open adjust the intake valve. Once adjusted continue to rotate the engine until the intake valve opens entirely and just begins to close, now adjust your exhaust valve. That cylinder is now complete.
What is cold clearance?
Clearing of the sky after the passage of a cold front, the cold air displacing the warm, moist air of the warm sector as a depression moves away. The process is usually marked by a veering of the wind (in the northern hemisphere, backing in the southern hemisphere), rising pressure, and a fall in temperature.
What part is between the push rod and the valve?
rocker armThe rocker arm is balanced between the pushrod and the valve spring. When the pushrod applies pressure to the underside of the rocker arm, the rocker arm pivots downward and compresses the valve spring. The compression of the valve spring opens up the exhaust valve and releases the exhaust.
