I'm working through starting my freshly rebuilt 2056. It has the original D-Jet and is a 1975 motor. At first I had no fuel pump, I fixed that.
Now there is no spark from the coil. I traced the lead from #8 on the fuse box to the relay board then out the relay board. I have 12.4v at the coil positive but no spark. I'm testing it with a light-type tester. No bueno.... It is a Bosch coil, i believe it is a "blue" coil. I read here that there should be 1.5 ohms resistance between the two poles on the coil with everything dissconnected. This one tests at 7.4 ohms. A spare coil I had had similar results with no spark at crank and 4.6 ohms resistance. I assume i need a new coil...... Right? |

QUOTE I'm working through starting my freshly rebuilt 2056 I didnt catch the new rebuild part. So you havent precharged the oil system yet? You should charge the system before trying to start it. Then you need to follow the cam break in steps |

Then you need to follow the cam break in steps By pre-charge the oil system you mean spin it up with the starter until it gets oil pressure right? Cam break in will be done according to Jake's instructions as it is his cam..... |
