Piston Kit 99909-229

First off, I am not a certified mechanic, I, am a small engine enthusiast, and my advise is given freely, from my personal experience of repairing my own equipment. I too, continue to learn more and accept advice, thank you, and here is mine..
1. Upon trouble-shooting diagnosis, suspicion was confirmed that there was a lack of compr ... Read more ession to the unit.(55psi) note: you need at least a minimum of 70-75psi or better, for proper compression to start the unit. In some cases, it is still possible that 70psi \"may\", not be sufficient. If you, do not own or have a compression tester, you, may still be able to tell if you have a compression problem simply by just on pulling the starter rope, if it pulls too freely, and with little to no resistance, chances are that is the cause, but it is always best to use a compression tester.
2. Ordered all parts through ereplacement.com!
Replacement of any internal parts on small engines is not an easy task for those who are not familiar or mechanically inclined. But it can be done. Tip: before disassembling, it is not a bad idea to take several pictures, or video, during this process. Thank me later.
3. Remove spark plug, and housing.
4. Remove carburetor and associated components.
5. Remove muffler, and ignition coil.(before removal, and since the unit was an older model, I, optioned to spray penetrating oil, onto to all bolts, nuts, etc. before putting torque into them, nothing worse than adding stripped screws n bolts during the process, but sh__ happens.
6. Removed cylinder, evidence of heat discoloration, and scarring on exhaust port side, plus piston ring had forged with piston confirmed diagnose.
7. Inspected crank and piston rod, clean out all possible debris that may have fallen inside the cavity. Blast of compressed air works very well. Advise: my opinion, should you have to replace these parts as well, it is probably better off, to just buy a new unit.
8. Removed and replaced piston(and associated components) note: rubbed piston with 2cy oil to help with cylinder installation.
9. Carefully, slide new cylinder, onto the piston, with special attention not to damage piston ring.(the top of the piston has an arrow, make sure this is pointing to the exhaust side of the cylinder). Secure cylinder to casing.
10. Attach muffler(this would be a good time to inspect and clean the spark arrestor screen, over time, they clog from improper oil mixtures and will bog the unit preventing full power), attach ignition coil(with proper gap setting, use your manual, or a business card works great).
11. Reattach carburetor and components. Note: since the unit was not used for an extended period of time, it was my option to include a carb rebuild kit into the repair.
12. Rechecked unit with compression tester, 95psi! Reassembled housing, installed spark plug. Note: prior to connecting spark plug wire, and I\'m not sure whether it matters or not, but I, decided to pull the starter rope slowly(about 10 cranks), just to feel the compression and for the piston and cylinder to lube and bond.
13. Fresh gas added, and she ran like new.
Good day! I, hope this helped, and best of luck in your repairs.

9. Still will not start.

1. Removed the spark plug.
2. Removed the plastic motor cover housing.
3. Removed the carb. and the muffler.
4. Remove the cylinder. Note which side is exhaust and which side is intake.
5. Remove the piston (little keeper that holds the wrist pen in may be a little difficult removing) (NOTE: The arrow on top of pi ... Read more ston points toward exhaust side of cylinder).
6. Use light motor oil and lubricate the piston, the ring and the cylinder. (The piston kit comes with everything needed. Make sure the gap part of ring meets at the stop in ring grove of piston).
7. Reverse the steps when re-assembling.
