My Yamaha started loosing power. You could kill it for a minute or two and then it would run fine for ten minutes or so. I changed all three filters and in doing so I noticed a hole in the vst filter screen. When I test ran it the problem was worse I could only get about 1300 rpm out of it if I tried to get more it would start surging really bad and even sometimes die... what do think might cause this?...........thanks.....Glynn
