=93 Joe,

There was a = posting=20 some time back explaining how to find TDC, but a search of my archives = didn=92t=20 turn it up.  I think it was Lynn Hanover who explained how to do = this,=20 but I won=92t bet my life on that.  This process worked for me on = my=20 20B.  So, I=92ll try to explain it for you.  =

 

Remove = spark plugs=20 for easy engine rotation.  On #1 rotor (nearest front cover) = rotate the=20 engine in the normal direction until you can see an apex seal in the = exact=20 center of the trailing spark plug hole.  Mark a convenient tooth = on the=20 flywheel.  (Helps to make a pointer)  Then rotate the engine = backwards until you can see an apex seal in the exact center of the = leading=20 plug hole.  Make another mark on the flywheel using the same = reference=20 point as before.  Now count the number of teeth between the two = marks and=20 place a mark on this tooth.  Rotate the engine back again to = align this=20 tooth with the pointer.  This will be TDC.  Now you can mark = the=20 crank pulley at the pointer on the front cover, or just use the this = new mark=20 on the flywheel instead.

As y'all may remember I = just built=20 from mostly new parts a 13b to replace the one that I think I = overheated to=20 the point that coolant was in the rotor=20 chambers.

 

I have spent the last = few weeks=20 since the build and a repair of the PSRU by Tracy rerunning wires to = better=20 routes, shortening wire runs (since I made most wire way too = long.....to be=20 fair to myself, the Velocity has a 17 foot + run from the IP to the=20 engine/firewall so a bit of excess was expected).  While I was = doing all=20 of this I kept tinkering with the engine to verify installation and = clean=20 up  and put things in a more "flight ready' condition since most = of the=20 concepts have now been proven.

Thanks to Tracy's test = modes I=20 know I have spark plugs a sparkin' and injectors injecting, if I can = just get=20 them to play nicely with the timing I should once again have a = running=20 engine.....hopefully I will know enough this time not to ruin=20 it.
