Does it have any compression? Are the needles set correctly? Did you try to lean it out?

the engine has been improving the performance after 5 tanks, but it is still slow. I believe it has compression how would I know if it haden't? the engine works. the needle is fine I adjust it to the best performance. Sorry, but I don't know what you mean by "lean it out"!
