1988 Suzuki QR 250 - after basic troubleshooting still no fire


Qrunnernewb

Recommended Posts

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.

Are you saying it has spark, but will not Fire?

The first thing on any older Suzuki Quad I check is to make sure the crankcase is not filled up with gasoline. If it is check the Rubber Diaphram in the petcock. It is common for these to fail and keep feeding the carb gas until the tank is empty.

I recently re-built a 88 suzuki, and if you have good spark, and your jets are clean, I would look at your enricher. Somtimes those old quads will not start without it. Make sure it can move up and down freely, and that it is connected to your enricher lever.

Try starting it with full throttle. Also, if you are pull starting it, pull back the lever on the right side of the head.
