I have a older Mercury 850 Thunderbolt and just got it back out of the shop? They replaced the choke on it and the Merc cranked with beauty, but today I was trolling for say a hour and it took 5-7 minutes for the Motor to finally crank? Does this sound like a Carb issue or timing possibly? I would appreciate any info I just got it out of the shop from failing on me and being towed off the lake due to the bad choke. Thanks for any reply or suggestions I have heard that particular motor is very cold natured. Thanks,
Tim
