I have a c15 mxs. It starts and runs fine when cold. But when I shut it off warm and restart it it sometimes acts like the starter stalls for a second and then starts.
A puff of black smoke comes out the stacks followed by white smoke for 20 seconds and then it clears up.
It is not making oil or burning coolant or blowing coolant out the overflow. What would cause this?
Cat c15 Mxs smokes at startup
