My 97 has a hard time starting when it gets near 35 or below. It never fails to start though.When it gets below 30 I usually have to crank it twice to get it started. It rolls over soooooo slow. The engine starts quick though. I guess I dont know where to go. Ive tried 10w30 with no change, had the starter apart and everything looks good and put new contacts in the solenoid. Has 2 of the biggest batteries you can get purchased from Oreillys and made no difference either. All cables and grounds good also. Starter plate and brushes looked good but I dont suppose that they could be bad? The starter just doesnt whirl it over well at all. Or could it also be valves out of adjustment ? It starts good once its warm. I am lost?
