So i have a 88 Suzuki quadrunner 250. I bought it s few months ago and have not been able to give it any attention until this passed weekend. Together with my automotive mechanic friend we took the carb out and cleaned it really well, drained all the gas that had a little water in it, blew out all the tiny particles with compressor and also blew out the gas line to make sure if is clean. Checked the spark plug to make sure it still looked in good condition and checked for spark and looked good. Filled the tank with fresh gas and put everything back together. We went ot fire it up and no success. Ive read other similar problems on line and think that all of these things are basic trouble shooting solutions except not in my case. Can anyone please give me some insight on what else my buddy and i can take a look at and troubleshoot to get this show on the road. We feel that it should have already started with what we did. By the way, the quad does crank and the motor does turn but doesnt start, not even a putt putt putt; off.
