1981 Volvo penta 270 4 cyl timing/dwell

[Jerbs1984]

I have a 1981 bayliner with a volvo penta 270 drive with the 4 cyl engine. I am doing a tune up and I need the specs for the timing and dwell for the points. I am very familiar with a points system so I know how to set it properly but I dont have the specs for degrees of dwell and timing at idle. If I could get that info or be shown where to get it I would greatly apreciate it. Thanks!

Hey thanks for the info. I set the timing to those specs and it was much better. It had not been tuned in years so the dwell was at 52 degrees and timing was only 2 degrees BTDC. Thanks again, runs much better.
