I just got an Arctic Cat Lynx 250 single cyclinder. Checked it today and it has no spark. First of all where can i find out what year it is? Next it has the spirit engine and i need to get it running has good compression but what should i check first to fix the spark issue? is there something that it usually is. also where can you get parts if you can? Any help would be great. Thanks

Well, I'm guessing maybe 78. The data I have lists an AB25F1 for 77 & 78 , F3 for 79 and F4 for 80 so it's possible 78 has a miss print and is actuall F2. First digit of the sleds serial number should tell you what model year it is for sure I.E. 7=77, 8=78 etc.

On the spark issue I always start with the switches, key, handlebar kill, throttle safety switch then check wiring and spark plugs.

You said this a new-to-you sled so you will have little or no history on when or how the (no spark) issue developed. It could a simple switch issue or a complex stator/ignition coil problem. Use aprocess of elimation on the switches. If you have no knowledge on how the electrical works then find a buddy who does.

The handlebar kill switch and throttle safety switch I believe share the same wiring harness on that sled. Once you locate the wiring harness to that side of the handlebar you should just be able to unplug it. I believe that year of sled had an ignition system which was open to run and the switches cpmpleted a circuit to ground to kill the sled.

The best test for the throttle safety switch is to have someone hold the throttle about 1/3 open and check for spark. The switch looks for slack in the cable and shuts off if there is slack. They were finicky switches.
