Hello everyone! I am having an issue with my new Mercarb that was put on this last fall. I have an 88 3.0 MerCruiser and it was starting and running rough last season. I replaced the rotor and cap, plugs and plug wires last year, and this year I had the carb and starter replaced this year. I also have new water separator filer, fuel filter and fuel line this year.
It is starting much better, but I can still tell that it is not idling quite right. I have made adjustments per the manual and tweaked them to get it idling better,but it is either to rich and it backfires from the carb when I am starting it or it idles rough and it eventually dies.. I tried to adjust my choke and it is wide open all of the time. When I loosen the screws and try to adjust the choke it still says wide open, it will not move at all. I am sure this is why I am having the idling issues that I am having. When it runs, it runs great, it is just when idling when I am having the issues. What am I missing about this new choke? Thank you for the help!
