2.7 First Start ?

[Daniel Cooper]

OK folks-

the 2.7 (actually a 2.9) went back into the 69 911t after a careful redo on the leaking throughbolts. Per the recommendation of the folks at Ollie's, I dressed and lightly countersunk the holes in the case, and then used the green o-rings and rtf for the install. Did each separately and very carefully.

Two issues on the first start attempt:

1) The motor fufs, pops, and bangs, rather than starts. The spark plug wires are installed consistent with the instructions in Wayne's book and are in the correct order (I believe). I also believe I did the static timing on the distributor correctly--line on the rotor lined up with the line on the distributor housing at number 1 TDC. Did I get it reversed 180 degrees somehow ? Any tricks to be sure it is correct ?

2) There is still one leak. Not huge, but problematic. It appears to be on left bank, on the case. Return tubes are dry, and the oil pipe connection is dry. It doesn't appear to be coming from the head or valve covers. I will take some photos when I get it leaking some more. Thoughts ?

Just roll the engine around to the compression stroke TDC on #1 or any number really and make sure the rotor is on that plug wire to start. or you may have it to far advanced or retarded too?

Once you have confirmed the plug wires are correct bring the timing mark for 1 just short of the mark on the case, then turn the ignition on and rotate the crank and listen for the pop of the points to check the timing. Do this with the dist. cap off.

Weel--

I put a Petronix pointless ignition in it, so I think I will have to use a timing light for this exercise.

OK--

rotated the distributor 180 degrees (turned the crank around to the Z-1 mark again) and hey hey, it fired right up !
