hey guys. I timed my 61 last night and it running a lot better but it has a hard time spinning over fast enough to crank now. I set it to 8deg with the vacuum line off and plugged and rechecked it a few times. it started up this morning when it was cold but it still didn't crank like it did yesterday. once I ran it once I coulnt get it to spin fast enough. I backed of the disi a little and it cranked up once but not when I tried to restart it. any thoughts
