My L28 was beginning to experience some hiccups lately. It would start and run easily enough but would run 'flat' with poor throttle response and the thing would hesitate until the engine was fully warmed up. First thought that came to mind was the carby. Don't all investigations start with the carby? However, the engine had been running well a while ago and had only started to degrade recently. I had a good look at things under the bonnet. I asked myself the question...."How old are these guys?" The leads were the original L20AET ones I got from a Jap import motor I bought way back in 1990. They looked good and weren't crossfiring but were they up to scratch? Time to break out the multimeter! The results were: No 1 = 10.31 No 2 = 15.58 No 3 = 14.99 No 4 = 13.25 No 5 = 11.49 No 6 = 16.60 These values were read with my ohm meter set on the 20K position. The new leads that I had bought were: No 1 = 2.05 No 2 = 1.91 No 3 = 2.06 No 4 = 2.19 No 5 = 2.49 No 6 = 2.54 These values were also taken with the ohm meter set on the 20K position. I even tested the coil to distributor wire. The original L20AET wire had been cut, so I'd never used it. Instead I had an 9mm 'eliminator' series wire that measured 0.96 on my meter, again on the 20K position. The new wire I got with the set measured 1.26 :surprised So I kept the old eliminator wire on. Firstly, I guess one could conclude that the 'eliminator' series of leads would be better than the "Top Gun" 8mm leads I've just put on the car. Then it would boil down to cost vs performance etc. However, I think that with the new leads I have on the engine, I should see an improvement over what was in there originally!! I'll do some 'cruising' and let you guys know how I get on.
