well, good news is i found part of the problem. bad news is.... i found the problem.
seems like the gasket blew AGAIN
between the intake and head right near the water jacket. it may not have blown... im thinking the intake may not be torqued down tight enough and is causing a water as well as a huge air leak. so its inconsistently dripping water in there causing the inconsistent sputter and the intake may be causing an air leak causing the surge in rpms at idle. i cant smell it in the exhaust tho so its burning it clean out the exhaust. i found it while i was changing plugs. numbers 1 and 2 are clean. the 3 and 4 plug had the nice brown haze it should of had.
anyhow... imma try and see what i can do tomorrow. hopefully i can fix it by snugging it down and hope it stops the leaks. if not i guess i gotta rip into it again
