Hi, Dragonej and the usual suspects are:
1. Spark plugs in bad condition or partially fouled.
2. Spark plug cables in bad condition and leaking.
3. Spark plug gap too close or too wide.
4. Faulty ignition coil, module, and or sensor.
5. Battery nearly discharged.
6. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
7. Intake air leak.
8. Water, dirt, or rust in the fuel system, carburetor and/or filter.
9. Fuel tank vent system plugged or carburetor vent line closed off.
10. Carburetor controls misadjusted.
11. Damaged carburetor.
12. Loose, dirty, or corroded ignition module connector at crankcase.
13. Faulty MAP, CKP, O2, and/or CMP sensors.
14. Incorrect valve timing.
15. Weak or broken valve springs.
16. Damaged intake or exhaust valve.

SOURCE: What did I break? entering

It sounds like the "middle drive" is damaged. You should seek professional help with this problem as a number of special tools are need for disassembly and reassembly.

SOURCE: I have a 2005 Honda

Your Honda is designed to give you many , happy, trouble free miles. Honda's are known for there stock quiet. Your Honda will NEVER sound like a Harley. When you modify it , it will only sound like a lawn mower with a blown out muffler. If you still want to proceed , you can drill out the baffles if you have a drill bit that is a foot long. If you decide to modify your stock system you have to drill through several chambers of the baffles to relieve the back pressure. With this method if you are disappointed with the out come you can not put the stock muffler back on. Drill only one hole at a time and drive the bike for a day to see if you have achieved the desired affect. If you relieve too much back pressure and develop a flat spot in your acceleration you will have to put in new main jets or a jet kit with needles to restore your performance. You will also have to install a jet kit if you change the exhaust system. I do not have a recommendation for a system . If you go this route be sure the system you pick has a baffle that is adjustable or changeable so you can adjust the sound. Warning: all aftermarket systems will be louder than you want them to be and ear plugs may not be enough to help.

Sounds like you may have a air leak on your intake manifold. Check all the manifold to carb bolts and manifold to cylinder bolts.

My lawn mower will start but after a few minutes of cuting it stops and have to wait ten or fifteen minutes before starting again

Sounds like you have an exhaust valve problem. This is something the that most people cannot repair, it requires special tools and knowledge. Something best left to professional.
