  • 302 trailblazer

    I have a 302 that started running like it's in one cylinder and will not give me my heat. Anyone know what the problem is?

          My Bobcat had an ignition coil go out on it, so only one cylinder operation. When I replaced it, I replaced both. I figured they both had the same amount of running time, so the other may be about to quit, too. I kept the one that was still working though. Check your oil level and make sure it is not getting fuel dilution. Mine was getting fuel in the crankcase due to the dead cylinder. I changed the oil and filter when I replaced the coils. If you want to find out which cylinder is dead, crank it up and lightly spray the exhaust manifold with water right where it comes off the head. the one not firing won't steam off much if any.

              Make sure you smell of the oil to see if you can detect a gas smell to it, not just look at the level. New sparkplugs won't hurt anything either.

                Did you ever figure out what the problem was with this machine? If so, what was it?

                  One of the 2 coils has failed. I like to replace them as a set. Have to remove the outer plastic cover. to get at them. I use a paper envelope to set them.

                    That's what I figured too. I replaced both of mine as a set since they both had the same run time. I kept the one that was still working, to have an emergency back up spare. I am still wondering if the OP ever got the problem sorted out or not.

                      Machine is fixed. Welds like a brand new machine. Looking back the machine over the last year or so seemed to weld colder than i set the dial. Next time the machine seems to do that I will change the coils out first thing.

                        So it turns out it was a coil for sure. Thanks for the update on the outcome, I was starting to wonder if we would ever find out what the actual malfunction was. Did you check your oil for possible fuel contamination? Perform the olfactory test to see if it is in there.

                          Actually my bosses machine. Told him to change oil, he just kind of blew it off. His machine... I own one with the robins engine. I would just change oil no questions asked.
