Just got the ngine in my new BN7 and got it up and running ove the last week. Yesterday I got everything connected and got it up to full operating temperature with no problems other than not being able to get it to idle. When I played with the carbs I could still not get it to idle. I went to move it and when I pushed the clutch in the mototr stopped abruptly and seized. I quickly got it out of the car and took it apart and when I loosened the bearing caps it spun right up again so luckily no serious damage found at this point. When I put it together the machine shop said that the journals all spec'd out at the original dimensions so I bought standard bearings for both main and rod from Moss. It was cold out when I put it together and the plasti gauge measured out near the smallest tolerance.
My guess is that when it came up to full operating temperature everything expanded and then bound up. That may explain why it would not idle. Does this make any sense? If so, is it possible to sdjust the bearings to make the tolerances larger? Any other ideas/
Thanks,
Steve
