Want this question answered?
then youre running about 8.5:1 compression
A popping sound (when running if it will run), backfiring, and low compression on one cylinder when testing with a compression guage.
A "Bad cylinder" or "dead cylinder" is a cylinder with Low compression psi. Symptoms: rough running low power can cause high oil consumption
when my 305 is running it has about 60 psi in all the cyliner
120-150 psi
As a result of wear and tear there was no longer enough compression in the cylinder heads to keep the motor running.
Compression socks can be useful for running. Compression socks are designed to help alleviate some pressure/pain on the leg, which could help with running.
The best way to find out the advantages of wearing compression running socks is to ask a doctor or a pharmacist. They can better tell you about compression running shoes.
Not running on all cylinders? Check spark plugs and wires Do a compression test to see if one cylinder is dead
i'd like to see 130-140 psi. gotta have 90 to fire.
It is the same as it is when you check the compression when the engine is not running. It does not change. It will only get worse as engine wears with time and as miles start adding up on the engine.
Start by testing the compression. It should be consistent within a few PSI on each cylinder. Any cylinders that have little or no compression probably have a burned valve. If all cylinders are up, check the plugs, wiring and distributor.
