I just pick up a Harbor Freight generator,has 13hp LIFAN engine on it. My question is,I removed the plug to check gap. and than decided to check valves settings,they where .06 on int. .08 exh. is what they call for, Now when I checked compression,it only had 66 psi. Last week I checked my 1864 cub cadet,and had 169 psi on both cylinders.
Now the engine has 10 hrs on it,and I think that he used synthetic oil and the engine is not broke in.What do you think.THX are they junk engine!

The Tecumseh engines, rebuilt, with compression release read about 60-65. I think that's what you're dealing with, release opening the valve early to make it startable.

Lifans are considered one of the better clone engines and they are supposed to be designed to run for 1500hrs which if true is a pretty long life. I would run the generator and see how it responds to a load. If it can support 70-80% of it's rated continuous power then I'd say you don't have any issues in the engine. If it only has 60 lbs of compression then it won't do well under a load.

It's almost surely equipped with an automatic compression release. Like was said, if it pulls the load ok, then I'd not worry.

It is absolutely equipped with a compression release. All the 13hp Honda's and clones have them.. Franky P has one and you probably even hear it click off when you start the engine up.
