HR21 SXM HR21-CL & HR21 SXM HR21-CL No references found online for these units.

I do not find any info to these specific models. They must be old or rare models. Most queries are PDM,SAMX,PDA etc. Both are self propelled,GV150 engines but different length operator control handles. They have 3 speeds,clutch brakes and full feature thottle controls. Help! Could use a service manual but the system is fairly self explanatory. The both run with great compression but hunt. No carb work has been done. Vacuum leaks present.Exterior gasket issues. I believe. Will make gaskets soon. Thanks! Ronn
