the compression stock, (goes up) compresses the 400cc of air/fuel in to a 55cc combustion chamber (all valves are closed,) and at about 8 degrees (before) TDC the spark fires.
on #1 the rotor most point to #1 spark wire, and bam, #1 cyl. fire and starts the power stroke (going down)
firing happens at end of compression cycle, 8 degrees before the end of it. in fact.
the distrib can be timed on any of the 4 top cap terminals.
but the harness will not reach on all 4. so.. it's timed at the 11 o-clock term. this is the factory setup. and referred to over and over in the FSM, to do other things related,
so that is why we use 11-oClock
the CMP has no idea at all were #1 is, it only knows how to fire 4 times per turn.
the Otto Cycle engine:
intake stroke (sucks, while piston going down) sucks in 400cc of air.
compression stroke , piston rises from BDC to TDC)
firing instant, is now, 8degreses BTDC. (combustion or power cycle starts NOW)
air fuel burns fast. and piston is at power stroke TDC to BDC.
now at BTC , piston goes up and exhaust cycle happens.
the distributor is installed so that the rotor points to 11 oclock cap terminal. #1 firing
with crank at TDC 0degr. mark (there is only 1 mark) or attempt 8degrees before TDC., id not try.
and both #1 cylinder intake valve are closed. (called lash loose #1)
then the clamp bolt is set,(tight) on distrib, base
the #1 wire inserted to 11oclock to #1 plug
then CW 3 to 3 plug.
then CW 4, etc.
last CW 2.
per drawing on timing page 8v
start engine, use timing light to hit 8 degr, BTDC, with light. timing freeze jumper in place.
