The typical cause of hard cranking on this engine is the valves needing adjusted. The compression release works off the INTAKE valve. I have detailed instructions for adjusting the valves, how to check the compression release and other helpful hints - - usually done by only removing the valve cover.

As for your rod play, rod and wrist pin should be tight. This is usually not a problem with this engine. What is a problem is the counter balance weight bushing and the eccentric on the crankshaft that the counter weight runs on.
It is not practical to repair those.

Thank you Walt. I tried adjusting the valves at the get go with no results,but before disassembly i was adjusting the exhaust valve as per Demseys 4th edition after i got it apart i realized the compression release worked off the intake.but again none of those parts looked worn at all.Thanks again Mike

At present, ALL B&S engines relieve compression via the Intake Valve EXCEPT the Vanguard "V" twins.

Check rod clearance with plastigage. If its .003 (Three thousandths) or less your OK. Usually if it's not scored it's OK

Set intake .003/.004 exhaust .005/.007

Thanks everyone
