hey everyone, i recently did a head gasket and cylinder head repair on my 2000 xterra 4x4 xe. everything came out great but im having some issues with getting my timing right. i have tried setting the ignition timing to the 15 degrees btc that is stamped on the hood but it seemed to lack any sort of power and was shit when it came to mileage. i was getting about 12/13 combined hwy and city and hwy alone maxed out at 14. when i originally got this rig i was getting 18/19 combined hwy and city driving and nearly 20/21.5 hwy only with a fully loaded rig with people and gear. i remember reading somewhere that 12btc was a good place to run at and have set it in that general area. now im getting about 17 hwy and 15/16 in a combined environment. where is everyone running your timing at and what kind of mileage have you been getting and what kind of fuel have you been running? i have been running plus this past few weeks.
