My /6 conversion is going on 3 years as it seems as many do. I had a local old school reputable shop build the stock 2.7, case was done at Ollies, .... should be a great engine. Finally trying to get her barking, but just won't take hold. While cranking she wants to start, but when I release the starter, she conks out. We have a spark (not real significant), timing is close, carbs appear ok.
Is it possible the valves or maybe rings are not sealing because the engine sat for about 2 years? |

windforfun, thought you are an EE Sir!
It's at 12V... A human will not even feel 1 amp at 12V. .071 amps X 12 v = .852 watts of power. You really cannot do anything "automotive" with less than a single watt. It will slowly take the battery down. That's it. Now .071amps at 400,000 volts could fry your ass... Maybe too many (IMG:style_emoticons/default/beer3.gif) (IMG:style_emoticons/default/beer3.gif) (IMG:style_emoticons/default/beer3.gif) ? |
