Small Engine Troubleshooting Problems? Ask a Mechanic Now.
HI, my name is***** will be assisting you.
The first thing that I would check is to make certain that the crankcase is not overfilled. This could happen if the carburetor is leaking fuel while sitting and it would get into the crankcase and cause a hydraulic lock in the engine making it very hard to crank over. The second thing that I would look at is the valve clearances, this engine has an automatic compression release built into the camshaft, if the valve clearances become too wide the compression release will not function properly and cause the engine to crank really hard.
It happens a lot with all different brands of machines, it is not just your model or machine. It has more to do with the fuel that we are getting and all of the additives that are put in the fuel. I do see this happen a lot more often than what I would like however it is normally a fairly easy fix and not terribly expensive to do.
I am not certain what you mean by a real answer. I have been in the small engine and lawn equipment repair business for 28 years. I do have considerable experience with this issue.
The first thing that I would look for is a fuel leak which would create your problem.
The next thing is the valve clearances.
I am sorry that you feel that you haven't received a real answer here.
