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? |

Any possibility of a vacuum leak?

Any possibility of a vacuum leak? Thanks, but it doesn't appear so. I attempted to connect an ammeter in series with the battery+ terminal and the + cable. I blew the fuse in my VOM, so I am suspecting there is too much of a current draw somewhere. Not sure how to track it down. |

I blew the fuse in my VOM, so I am suspecting there is too much of a current draw somewhere. Not sure how to track it down. Ammeter is good for 10 amps. If you tried cranking that draws about 75-100A. If you blew a 10A fuse with just ignition on, then you definitely have a VERY large current draw somewhere. Coil / CDI box should only be 4-6A draw. Lights or other large current drains turned on at ignition on could take you well over 10A fuse. You either need a shunt resistor or a DC capable current clamp if you want to measure more than 10A directly. Have you confirmed the basics yet? PS - why are you measuring current? To confirm the coil while cranking you only need to monitor voltage at the coil while cranking. |

To confirm the coil while cranking you only need to monitor voltage at the coil while cranking. Basics, yes. Fuel, compression, spark timing ok with spark. With everything off, just connecting the battery I get a larger spark than I would like. I am suspecting a large current draw, earlier I disconnected the alternator with no change. Pver the past several months I did some metal work, hell hole and other misc metal repairs in the engine bay as well as adding a /6 mount. Hoping I did not damage any wiring within the main harness.
