Didn't think the vacuum line would make that much difference, but tried that way. I can get the timing mark to be where it should be, starts good, seems to run ok. But, it just seems like the engine is working a little hard. I don't have much vacuum either (13).Difficult to describe..seems to have minor vibration and smells warm. I tried to keep the thing as close to original as possible, cause it was my grandpas, but I really need to put a set of gauges in this thing so I can see what is going on all the time.
