ok first off new to site And boating. Hi to all.
I am working on a 1989 sport craft 1900 sprint br it has a omc 4.3 that came out of a 1990 four winds it’s not a roller motor it has flat tapets not sure what the deal is on that one that’s a different topic and a oms out drive which I pray that I have adjusted correctly per the manual. Took boat out twice last year after putting in the motor that I bought. due to the other engine had a crack block and that’s how I bought the boat with bad engine. All did good when I took it out. Now start of a new season and performing maintenance.
question is I have the new points set to .019. Now after start up and engine warmed up I worked on the dewell. The dewell is at 29deg book calls for 39 deg and the points are at .010 now and the timing is set to 6 deg before top dead center. Does this sound right. If I try to get 39 deg the points would probably be just about closed all the time. I am I missing something. All of this is done on the muffs.
