After rebuilding my 450 k5 it is time to let him come alive ....
before starting I like to know if the advancer is correct?
There is a dot on the moving part and a line on the static part.
Is it correct there are opposit of each other. The foto is upside down....
Please your advice,

Hans

Pretty sure your breaker cam is on the advance unit 180° out, the dot lines up near the line on mine

No problem - backfiring through the carbs? I'd expect so. BTW - as I'm sure you are aware, having had the engine apart, the 450 engine does not retain any oil below the cams and followers. It relies on oil flow to fill the camshafts (by way of the oil passages up the 2 right hand cylinder studs) and that lubes the cam bearing surfaces and the followers out of the holes in the cam lobes. All that takes a couple of minutes to accomplish on a cold start, so keep the revs as low as possible for the first couple minutes to avoid undue wear on the lobes and followers. Other than taking that precaution, they're pretty durable engines
