[QUOTE="OMC_Rookie, post: 403927, member: 20419"] Thanks for looking at this pappy, I've always had issues getting this engine to run well at lower rpm's - has a tendency to run relatively rough and splatter a bit especially with continued low rpm use (ie setting and retrieving crab pots) I've spent time trying to tune it with this low speed needle however found it not to make much of a linear impact when adjusting the screw as per the proper instruction. Following this I decided to purchase a carb repair kit - upon dismantling found this issue and though I better check if this could be the source of the problem and not to waste a carb kit on it. I pulled down my old 25hp evinrude carb of similar year to inspect. The 25hp carb has a near perfect inner circle for air flow whereas the 30hp appears to have a gouge out of bush. I'm almost leaning towards putting the carb kit into the 25hp carb and throwing that on my 30hp engine (I know the blocks are the same). but its a shame to waste 5hp. [/QUOTE]
