I recently replaced the intake gasket as well as the distributor o-
ring. I got the top end back together and adjusted the valves as
specified by the manual that i have. my problem is that the truck
idles incredibly high after setting the timing to 10 degrees before
TDC and the truck has absolutley no power. I drove it a mile and it
barely got me home. I am hoping that i didnt overtighten the valves,
but i think it is looking like i did just that. I dont believe i have
a vaccum leak creating high idle, but that would cause my lack of
power anyway. would it? i also read from some fellow s10 owners that
you need to unhook a bypass wire from the ECM when you set timing. Is
this true? can you steer me in the right direction?

valves w/engine at oper. temp. & idling. Back off each one until it starts
clacking, then slowly tighten until that one's clacking barely stops the
noise. This is zero lash. Tighten it an additional (whatever manual
specifies--often 1/4 turn) amount, and go on to next one. Good idea to
repeat procedure once again to obtain the "fine" tune. s
