Answer If I was having a problem with high cylinder pressure. I would start with checking for a restriction in the muffler. I would unscrew the muffler and take it off then recheck the compression. If it is still high then check to make sure that the exhaust valve is going up and down and that the exhaust valve port is not restricted. That is where I would start. Good luck.

Compression anklets, socks, or long hose should NOT cause bruising. Most likely, the hose are too tight, too much compression. Talk to your doctor for a prescription for a lower compression product.

What are the advantages of compression?
Compressing files or images enables you to (sometimes dramatically) decrease the memory space that file will take up. Without going into to too much detail, it works by 'approximating' the information in the file, thereby lowering the detail and filespace. However, compression also reduces the quality of the file, possibly corrupting it if it is compressed too much!
Does Briggs stratton engine has to much compression acts like the battery is weak if the plug is out turns freely have set the valves to the best of abilities is there something else?
No, it can't have too much compression. It sounds like the battery or starter motor is going bad. Fully charge or replace the battery, then have the starter tested.
