How do you adjust the idle on a 300EX?
How do you adjust the idle on a 300EX?
Counter clockwise to idle up, clockwise to idle down. Do you have a balloon? Thats the one. When the quad is warmed up, turn it, till you like the idle rpm.
What is the result of weak compression pressure?
This can cause deep scratches in the cylinder walls, which can cause the compression to leak down into the crankcase. If you have a very old engine, it can also happen that these cylinder walls are just worn, and therefore the piston rings will not be able to seal properly.
How much compression should a 350 Chevy have?
You should have probably somewhere in the 150-170 psi range.
Should compression test be done hot or cold?
The compression test can be done either hot or cold. A hot compression test is done with the engine warm to ensure all the parts are up to temp and the clearances are as expected. If you suspect damage you might just want to perform a cold test instead of letting the motor sit and run to warm up.
What is the most common valve failure that affects compression?

| What is the most common valve failure that affects compression? | Degradation of the valve face and the valve seat surface |
| why must the “charge” in the combustion chamber be compressed before ignition | Improved vaporization of fuel and air |
How can I improve my engine compression?
The tighter you can get this quench area–or the piston-to-head clearance–the better the engine will run. Moving the piston closer to the deck surface also increases the static compression ratio. There is also a limit to piston-to-head clearance.
At what position is valve timing set?
Every time we assemble a four stroke engine we have to set the valve timing. It’s quite simple but very important ! Set the engine at Top-Dead-Center (TDC) of the compression stroke, set the timing marks on the cam and you are done.
