I'd say that ur compression is going downhill. has it gotten easier to kick? thats a definate sign. you'll still want to check it with a guage. or just rebuild it for the heck of it.
i do feel bad for you mechanics out there when someone brings something in that they've messed up. HOWEVER, i think that is one of the problems with America today (lol). even tho things get messed up i think it is better to know something about the machine your using. take all these women (no offence) that drive cars. i'm not bashing on women or anything, but most women just have no idea how things work, then when the simplest thing goes wrong they have to stop the whole world and get someone to come help them that usually takes advantage of the situation and charges them out the butt for it.
so i think it's good to mess things up in the garage a little, then when you get out on the road, if something happens you can help yourself.
and maybe it's just me, but i like workin on motors. and would rather do it myself and know no corners were cut (or at least know WHICH corners were cut, lol) and save the few hundred $$ that someone else would have charged me.
although, sometimes, it's just not worth the frustration hahah.
