I know bits a pieces of this have been discussed before and I've researched other forums but I haven't been able to draw a useful conclusion. My engine misses at idle and then has an after fire in the muffler. I don't like this happening although it doesn't happen in flight. I'm installing a JPI 830 soon but don't have engine monitoring yet. In searching for the problem I checked the intake bolts and they were fairly loose taking at least a turn to get 96 in-lbs. After twerking the bolts to 96" the misfire seemed to disappear and the engine ran smoother (could have been in my head). Its a week later and the pops and farts are back and my engine is also misfiring. Time to change gaskets, I've ordered both the lycoming and superior gaskets. Three questions: I also ordered the red o-ring gaskets for the other end of the intake tubes. Do the large O-rings have to be changed after removing tube or can I clean up tube, lube the end with clean oil and stick it back in? Do you guys use goop such as permatex #3 avaition, on the paper gaskets or do it dry? If you are in the pro-goop crowd, which is your favorite gasket sealer for this purpose? How about power grab, hold it tight for 30 seconds and go fly! Thanks, Adam
