[worn]

Finally I got the motor in my 1980 rebuilt and attached to the car. Want to run in everything but the motor starts and then dies after about 4-5 seconds. When it first starts it sounds pretty good, running up to 2-3 k RPM. I checked the timing, and it seems pretty close, with the timing light blinking away to indicate that #1 is firing for as long as the motor spins.

The motor:
911 SC with stock fuel injection
Dougherty DC15 cam shafts
Backdated SSI heat exchangers
While I was at it, 98 mm Mahle cylinders with CP pistons
MSD ignition with epoxy potted blaster coil.

The only thing new since it last ran are the pistons and cylinders.

Any suggestions? The thing will run, but only for short bursts. I cannot quite get from the key switch back to the throttle butterfly before it dies.

Left the whole mess lie on the lift and drove my TR6 home. Which was pretty good.
Thanks
