[DMCForum] Tuning



Now that my front-end has been fixed I'm back into the engine.

Martin: You recommended I clean out the distributor and I did so. The
timing mark jumps off the scale between 1600 and 2000 RPM. (I can't
look two places at once).

I installed the new idle tube O-ring and verified it is sealed. I
sprayed all around the engine (again) and the only leak I could find
was the golf tee I plug the CO screw with. (slight). I fixed this.

Before repairs I was running around too rich and underpowered. When
warmed up, the engine would idle at 1000/1100 RPM.

After I put the O ring in and cleaned out the dizzy, I leaned out the
CO screw, checked the timing and made a very minor throttle set screw
adjustment to make the idle perfect.

Power is MUCH improved. Before, the engine wouldn't rev -under load-
beyond 3500 RPM. Now it'll redline. I feel I have good acceleration
and power. The only thing that bugs me is the engine still "farts" or
pops. It doesn't do it often but it bugs me. I have to find that.

I am having a hard time figuring out how close I am to having this
right because I've never ridden in a properly running DeLorean under
hard acceleration! It -seems- right but maybe I should have yet more
power....? I need to ride in Mike Cohee's car and have him put his
foot into it.

I also need someone to ride behind me and tell me if I'm still gassing
people. I can't smell fuel in the exhaust anymore but still...

Lastly, one more time: What brands of wires can I get that are the
right kind, that are PRE-MADE and have the proper boots on them? I
plan on using Bosch copper plugs and buying a higher voltage coil.

Thanks,

Rich
