Hey guys, I was wondering if you might help point me in the right direction. I have a 93 Ski-Doo Mach1 with the 670 Rotax / duel carb. I am having a bear of a time trying to get it started this year. I have flushed the fuel system completely, and cleaned out the carbs. I have disconnected all the kill switches and ign switch (this is a pull start only) I am getting spark (inline spark tester) and I know that I am getting fuel from the wet plugs. I can only get it to start (no belt) about every 100 pulls or so with the throttle wide open. I can feather the throttle and get it to run for about a minute or so (lots and lots of black smoke), but when I try to get it down to idle it dies. I had a friend watch the spark and he said the spark cut out before the engine died. Upon trying to restart, I can not even get it to fart unless I let it sit for an hour or so. I am thinking that there may be something wrong with the CDI box, coil, stator, or maybe the ignition trigger. Any ideas would be helpful. Thanks for any info.
Jon
