My CX500T will not idle properly. When I start it, I have to hold the thottle open to keep it running and it seems like it is either starved for fuel or is not getting proper ignition. I pulled the plugs and checked the gap and they were fine. I cleaned them the best I could do with a rag. A little history is that I just got back from overseas deployment. I put fuel stabilizer in it before I left. I charged the battery and fired it up. It ran just fine. No problems for over an hour. I go back out the next day and now it barely wants to run. Any ideas?
