Hey guys,
I have a 95 Johnson 50 hp that has a problem start when temps are below 40 degrees. It seems to run on just 1 cylinder, then after it runs(stutters) awhile and warms, it will go on 2 cylinders. I have had it not start at all when cold, like it isn't getting spark. Then get home and heat up my plugs QL78YC with a torch, put them in and it fires right up. Am tempted to line the inside of my motor cover with some heat tape to keep warm. In the summer it runs just fine. Is there a different plug that will tolerate colder temps?
