Been lurking for awhile but today i have a question regarding my (i think) Silver Century Plus ser # CPC 31301L, which drives my Vivacity 24 sailboat when there is no favourable wind....
Cutting a long story short it has been working well but stopped the other day out of the blue after 6 hours of continuous running, excepting fill ups...(probably i have close to 20 hours running this summer, sometimes 2 and 3 hours in a stretch)
It seems the points gap had closed up, I don't have a manual but i did some reading of the FAQ, searched the Forum and garnered enough info to have a go at setting the points.....
I have been somewhat successful by sort of hit and miss and i say that because of what i perceive to be my problem....
That is top dead center of the piston, checked with the plug out seems to occur when one of the 4 spokes of the flywheel is directly over the points adjustment screws....
I have tried setting the points before and after the spoke problem and had the motor running but the gap was less than 16 thousands not the required 20....and now after closing everything up the motor refuses to fire.....
also and i don't know about these matters, the points seem to remain open upon flywheel rotation longer than what i'm accustomed to with old Land Rover engine points, i think this is referred to as dwell......It would seem to me the points should remain closed much longer and only open ever so briefly at top dead center......
Have i made any sense with this query
