Need some help on my 1983 90 HP Evinrude. I just rebuilt the carbs but the engine is hard to start the first time. Once I get it started it starts with just the bump of the key the rest of the day. Any ideas? I have had many evinrudes and mercurys over the years from 9.9 hp to 150 hp and have had this issue with Mercs before but not with evinrudes. with the mercs I would just choke them till they hit. this doesn't seem to work with the evinrude. thank for any help!
