It saddens me to read these posts. This sounds not one bit like the Terry Landrum I know. It seems that you have been meeting a different WWS Terry than me. Are there 2 of them??? I am fortunate to have over 25 of Terry´s saws for me and my crew to use. Some I sent to him for porting, and some he aquired for me i the US and ported. I live in Norway, and run a treremoval and treepruning company. 4 times I ordered saws from Terry, and 4 times he delivered. Wonderfully powerful and reliable saws. Stihl 150 and HQ540 arborist saws, and HQ 550,560,576,390 and 3120´s. The first saws came from him 4 years ago, and the last in 2018. With one exception they all run completely reliable. The exception was a 550 with just a tad to much squish, so the piston ring got just barely loosely pinched in the piston groove. Terry sent me new piston and cylinder. I prepaid all orders to him (quite substantial payments), and every time he delivered what was agreed upon. I am very grateful for the wonderfully efficient saws he mad me, my company would not be doing so well without Terrys help.
