I Have A Xingyue Group 5000watt Generator Dy5000l I Am Haveing A Problem Pulling The Rotor Off To Get To The Compression Release I Put 2 Pins Through Rotor And Used A 16mm X90 2.0 Thread Bolt Screwed Into The End Of Rotor But Rotor Will Not Pop Off Crank I Used Lube Inside And Tapped On Sides With Mallet Rubber Hamer ,the Company Will Not Answer My Fax And I Can Not Get A Ring When Calling The Number Has Been Disconnected And Is No Longer In Service.i Just Got Through Putting A Honda Exhaust Valve In And I Double Checked Valve Clearences And Tried Adjusting Down To .002 On Both Valves But There Was Still Too Much Compression To Pull Crankover Flywheel Key Looks Great Also .
