i recently bought a 1982 305 csr it has 1,700 miles on it but it hasnt been run in 20yrs. i put in a new batter,oil,air filter and spark plugs.i cleaned out the carb as best as i could i just used carb cleaner spray .it doesnt run it turns over but it wont fire. i tried pop starting it the bike only went about 4ft then stopped. if theres anyone who could tell me what the problem is and how to fix it it would be much appreciated. this is my first bike so i dont know alot about motorcycles.
