Well I have been reading along on your trials and tribulations, looking at the pictures and will chip in with my two cents. First the thing with the bent wiring connections above the oil pressure tie in hose is part of the emmisions, you dont need it. Second your wiring is in need of attention, if that red wire taped up is any indications your whole problem is probably dirty contacts and or broken wires, putting power to the coil with an additional wire tells you that. Step back and start cleaning stuff up, check your wires for continuity, clean up your grounding wires, there are no quick fix's when your dealing with a car 35 years old, and your old Allison system is probably still good seeing you have the same issue using the Protonics. Best of luck Brett.

Thanks for the advice. .. You know the spark i got from the flamethrower did look kind of weak. I think what I'll do then is go back and clean up all the wiring and then try the lucas 25D coil.. Questions: 1. Do i need 12V directly from the battery for this coil? bearing in mind I don't have a ballast resistor? 2. I'd really like to use the Flamethrower coil so is there a way I can get the necessary 12V to it? I already ran a wire from the battery but I guess the built in ballast resistor (the red wire with the tape) is reducing the voltage, i.e. when I put my multimeter on the coil it only reads 10.8V). 3. When I did the coil test (flamethrower) I got a spark but when I connected the cap, rotor, etc. and tested the #1 Spark plug there was nothing...would that just suggest not enough spark? I would have thought I would have got something from the plug test just to show that it's working? Thanks for all your help.

OK I got it running.....sluggish though...I did get the timing correctly adjusted though...It smokes a lot from under the engine, does that indicate a problem with the exhaust manifold?? Also, does anyone know how to adjust a weber carb (see pic below)?? Attachment: IMG_2561.JPG (Downloaded 41 times)

Most likely you have an oil leak from the exhaust cam cover. Oil drips down on the exhaust header, and starts to smoke when it heats up. The cure is a set of rubber gaskets from the JHPS store. As far as the Webers go; The picture shows a set of Dell'Ortos... If the jetting is correct, it is simply a matter of balancing and idle mixture adjustment. See if you can get hold of a CarbTune to balance the carbs, it does make quite a difference on the off-idle pickup. -- Joachim Last edited on 11-07-2010 01:37 am by subwoofer |

These are the ones: http://www.jhps.com/mm5/merchant.mvc?Screen=PROD&Store_Code=jhps&Product_Code=RCG&Category_Code=CC It really works. Not a single drop has escaped since I installed them. -- Joachim

One more question... On the Dell'ortos .... what's a good setting for the idle and mixture screws (just to get to a good starting point?? I think I mucked them up initially and I have problems starting the engine....is it all the way closed and 4 turns back for the mixture??
