Diagnosing a Honda GCV160 That is Hard to Pull the Start Rope

In this video I go through troubleshooting a Troy-Bilt w/ Honda that I got from a yard sale that had been sitting. Turned out the cam compression relief had failed and made the rope really hard to pull.

I have the exact same mower so the procedure for changing the cam gear was of great interest. Thank you for your very clear instructions which I’m going to save if it ever comes up.

This is a super video, thank you. Are old Honda HRS-21 mower GCV-110 engines similar?

[@JLPicard440]

HI! Thanks for the great feedback! I looked up the HR 21 engine and it looks like it's one out of the 70s... I could not actually find anything on the GCV110 at all...

I bought A Troybilt mower with GCV 160 engine at a yard sale. It has 150 psi when spun with a drill. That's my prob;em, right?

[@JLPicard440]

HI, it could be! I also mentioned in the video that these engines have an issue with the valve getting stuck and as a result it cracks the rocker arm. It'll cause the same exact symptom as the compression release. You'll have to take off the valve cover to look and see..
