Small Engines (Lawn Mowers, etc.): Honda HRB216HXA push mower, honda hrb, starter cord

Question
QUESTION: I serviced my mower new oil gas and cleaned filter affer, the mower started on first pull no problem. Then i took the blade off to have it sharpened. I put the blade back on now it wont start and takes alot of power to pull rope. The rope pulls but you if very hard. What could i hav e done to make tbe mower this hard or tight to pull. I did finally get it to start but wont stay running.

ANSWER: Did oil get in the cylinder or carburetor/air filter?  Is the blade on securely?

Remove the spark plug and pull the starter cord several times to see if any oil comes out the spark plug hole.

Remove the air filter and see if it has oil on it.

Remove the bottom float bowl nut on the bottom of the carb and drain the fuel out of the carburetor to see if any oil got in the carb.

Let me know what you find.

QUESTION: Blade is secure. No oil on filter. No oil in carb
Removed plug pulled several times did not see anything come out put my pinky down plug whole came out clean
To be clear when i say hard to start i mean i have to use all of my strength  both hands my back and legs to get the rope to turn over the engine. This HONDA HRB 216 is self propelled

ANSWER: Many times the difficulty pulley the rope is caused by oil in cylinder called hygrolock.

Were you able to pull the cord easy with the spark plug removed?

QUESTION: The problem was the new bolts i put in the blade. They where to long and put pressure on the clutch. But thank you. The mower does idle wierd though. It repeats: fast (loud) to slow ( soft) and almost dies if i slow the throttle. Mowed whole front yard still does it. Before i mowed i did accidentally remove carbarator when draining float bowl. Any ideas?

Answer
Dirty carb...very common with today's engines as the carbs are tuned so precise to meet emission standards.

You will need an air compressor, a small one will do.  Remove, dis-assemble the carb and clean by blowing compressed air through all the orifices (holes) and spray some carb cleaner through the holes as well.  Blow clean again and re-assemble and install the carb.

Cleaning carbs accounts for over 85% of repairs these days.
