That's a useful tip!
As of now, the engine seems to be an engine again, as opposed to the boat anchor it's been lately.
This wouldn't have happened without the patience and good advice from you all!
Thank you very VERY much, all of you!
After turning the rotor 180°, it fired up, but not too good. Died after about a second. Even had a nice flame inside the air filter. But it fired.
So I advanced the timing, got a little better, but died rather quickly again. Turned the distributor housing some more counter-clockwise, and it fired up good. Had to encourage it a little on the throttle, but it was firing stable and I was soon able to keep it at 2K RPM.
Naturally, it overheated, so after 10 mins, I shut off, and let it cool a little. There was a bad coolant leak from the upper radiator hose, due to the hose clamp deciding to give up the fighting spirit in the heat. Had to top up with some water.
10 more minutes, and yet again overheated, but by now the cam has run at 2K RPM for 20 mins.
Changed oil, changed from pure water to antifreeze mix coolant, and now I only have to hook up the Lokar throttle wire, and kickdown wire before I can take the Chally out for a spin!
Might have to adjust the idle too, but I have a couple of Holley books that should help me sort that out.
