Hey guys I've been attempting AG for a while now but always seem to have problems. My latest batch, a pumpkin ale based off Golden Boy Pumpkin Ale recipe I found here, seems to be fermenting slow. I brewed this recipe a couple weeks back and it came out great! My worry is that a couple days after putting the first batch in the primary it was mostly done (OG: 1.05 FG:1.014). This time I checked the beer 4 days after putting in primary and the reading has barely dropped (OG: 1.045 Current: 1.034). I've always had problems with low efficiency ( usually in the 60-70% range), but this time my efficiency was around 55%. Can this be causing a stuck or slowed fermentation? Should I swirl the yeast cake? Wait it out a little longer? Any help would be appreciated. Here is the grain bill:
7.00 lb Pale Malt (2 Row) US (2.0 SRM) Grain 52.83 %
3.00 lb Munich Malt (9.0 SRM) Grain 22.64 %

0.50 lb Caramel/Crystal Malt - 40L (40.0 SRM) Grain 3.77 %
0.50 lb Caramunich Malt (56.0 SRM) Grain 3.77 %
Mashed at 150-155 for about 75 minutes, 60 minute boil
