2 people---will not take long--Evil Female in you house will do!
Disconnect the COIL so it CANNOT START
Take out #1 Spark plug
WATCH OUT FOR THE FAN!
Stick your Finger/ Thumb in the Empty Hole TIGHTLY!
Evil Woman "BUMPS" the MotorOR TURN IT IN THE CORRECT DIRECTION WITH A WRENCH
(REGARDLESS, IT WILL BUILD COMPRESSION, BUMPING WITH THE KEY, SOMETIMES LETS THE ENGINE "ROLL OR KICK BACK" WHEN THE KEY IS RELEASED. SOMETIMES USING A WRENCH IS BETTER)
This is a 4 cycle engine--the crank rotates 2 times (piston up 2 times)for every one time it makes a Cycle
ONE IS EXHAUST STROKE (pushing toward the top)
The other is COMPRESSION STROKE--THIS IS THE ONE WE WANT!
This is the only UPWARD STROKE that both valves are closed and air/ fuel pressure builds up--when it reaches the top, this is TOP DEAD CENTER (TDC)
So here's the deal--when she bumps it and YOU GET A "SPIT OF AIR" by your thumb----STOP STOP STOP! (You may want to practice a time or two, we want the BEGINNING OF THE SPIT--NOT AFTER YOU PASS IT!)
You are headed up, on COMPRESSION!---Beginning of the spit
Now you must turn the engine BY HAND, in the SAME DIRECTION it normally turns---using a socket on the HARMONIC BALANCER NUT and a Ratchet/ pull bar/ pull handle
TURN IT SLOWLY until your TIMING MARKS LINE UP ON "ZERO"
THIS IS TDC!
THIS IS MY JEEP CJ 5 6 CYLINDER (258) ON 8 DEGREES BEFORE TDC (BTDC) AND THE NEXT PIC IS TDC (ZERO) YOURS IS DIFFERENT!
Remember this happens twice in a cycle (timing marks line up)--only once for the compression stroke. Compression will not build until both intake and exhaust valves are closed
With your modifications---if the cam(s) ain't timed to their correct open/ closed positions for "TDC"---this "Old Time Method" just ain't gonna work!
