I have a 1986 Suzuki LT250R, but it has a 521.2cc 2-cylinder Rotax snowmobile motor in it. When I bought it, I would hit the primer 3 times, pull twice and it would fire right off, and idle. I rode it maybe 5 times with no issues. The bike sat for about a month without running, and all of a sudden, I couldn't get the thing to run. I would have to hold it full throttle, and pull it over almost a hundred times to get it to light off. Of course it wouldn't idle either, but as long as you kept it running, it was OK. I put fresh spark plugs in it, and it didn't help. Yesterday I couldn't get it to start at all. I am sure this is a fuel issue, so the question is, what would cause it? I have 93 octane mixed 4 gallons/1 quart with Wal-Mart 2-stroke motor oil. This is the first 2-stroke I have owned, so any info/tips would be appreciated.
