How Does One Correct Low Compression?

[inspectorcritic]

Solution probably gonna be tuff pull the low end apart don't have a machine shop or a press.

almost always a gasket if top end isn't so old it is worn out - clean motor very well, ride it a bit and look for oil seapage

I pump the compression test held it for 5 minutes no leaks so that is not the problem.

compression is tested with a gauge in the cylinder not the bottom end.

How many miles on the engine?

how low is it? about 25 pounds is almost always a crank seal

rings, gaskets, crank seals. hard to say without having my own hands on the thing but those are the first things you should check

If it's the seals, I would go with the higher quality double lip seals. I had chronic seal problems until I went with this kind of seal.

Pull the head and look in the cylinder. How old is the engine?
