Hello,
I currently own a AXE ROSSI .21 Cobra 198R21 and have about 3 1/2 Gallons through the engine. I noticed some fatigue in the connecting rod when the piston is at TDC. I can feel a slight movement back and forth with the flywheel while the piston is stuck at TDC. Anyhow I took the entire engine apart and didn't notice any damage. I would like to hope I caught it in time. Anyhow, I have read that these engines require a rod rebuild after 10-15hr. mark. Now, this would not be my first race engine as I have replaced them before. Anyhow, I am wondering if this is the correct part number for the rod. PN. 16008 $45.00The engine still has a lot of compression and pinch left. Will this new connecting rod last longer than the one I had before?

Also, I purchased a Turbo Head for this engine and was not aware that the Novarossi 6 Turbo Plug doesn't seal. I ran the engine and it ran actually fine, but when I came home to check it I noticed it was a air leak. Now I tried a O.S P3 plug and it worked no air leaks. The question is now, I didn't strip any threads nor did I force the plug in the head will I have problems trying to use a AXE Turbo Plug later on?
