Hey all, been awhile since i posted anything around here, thankfully its because i havent needed to, shes been running great, well i went to pop in some new plugs this afternoon to find the 3rd plug in from the front, the threads are going, im afride next time i may not be able to get the plug to stay in properly, for now its secure and well, anyone have any tips on how i should proceed when the time comes, new head? used head? etc etc, i doubt its possible to fix threading there as the plugs are standard sizes.
