Smoking a 4.88 lb shoulder and it stalled big time. It was 147 at 4 hours and in the last 5 hours has only gotten to 175. It is looking good but based on time I will pull it late tonight and we will have to eat it tomorrow. I did recheck with another probe just in case the other was off. Wow well, it will still be good tomorrow. I have come to the conclusion the the smaller one take longer to smoke the a larger one. It may be due to the fat vs meat, I do not know, but any time I have had one under 6# it stills to stall badly. Hmm think a beer may make it go faster lol
