Perry, I would try swapping the plugs to different cylinders and see if the problem follows what currently is the #2 plug to whatever cylinder you put that plug in.

Subject: [TR] TR3 Question -
Was out of town for a couple months and my little TR3 was put to bed without any preparation (left town in kind of a hurry, and drive the car practically daily in decent weather.
When I got back, it wouldn’t start without starting fluid, and ran terribly, was rally hard to get off idle. Needed choke to run. Underivable.
So I went through what it could be - figured something on startup. Put some fuel treatment in the gas - thinking it had lost oomph while sitting, but running was really bad. Changed plugs, checked fuel pump, timing (have pertronix) etc. seemed like cylinder 2 was not firing -
Plug was definitely not fouled or as dark as other plugs. Checked wiring - switched plug wires, new red rotor, new distributor cap (I use the MG cap with push in connectors), then found that if I removed the plug wires one at a time, it would nearly die, except for number 2.
Checked valve lash and reset, tied again - checked compression - 133 - 137 across the board. Got it running again, got better, then ran good enough to drive - went fine.
OK - So maybe bad gas. Would Jake sense that the fuel srtailizer and octane booster finally worked its way to the cars. But, still, cylinder 2 doesn’t affect engine running as much if spark wire pulled. Is this a function of the firing order? I cant imagine what it could be - cant be carb - feeds number 1 as well. Has big spark, as do all the plugs, and from the cap.
Any ideas? Sorry for the length of this post and thanks in advance!
