Default 2000 Quad Master 500

Runs but has flooding issues...my mechanic doesn't think it's carburator/gas problems ...thinks it's the CDI or somekind of electrical but Suzuki is saying if the bike is running at all it isn't the CDI...any info is appreciated

First off, what do you mean by "flooding issues?" If you are getting fuel in the airbox and/or crankcase then you certainly do have a carb and/or fuel tap fault.

No fuel in the crank case or air box...the bike won't idle and sputters up when riding at quarter throttle or less and can smell it running rich...replaced the float needle valve and seat and diaphragm and spark plug...the ignition coil is reading 15k ohms but the local Suzuki dealer said if the bike is running at all it wouldn't be the coil or CDI...

The spark plug is turning black a little and it's almost like the choke isn't fully turning off...plus the bike only has 3500 Kms on it

Could be that you are right, and the choke isn't going off. The plunger can stick in the carb, but one fault I have found with Eigers is the outer cable swelling and getting longer. Weird I know, but water gets in, rust starts and forces the coil of wire that forms the outer cable, apart. Stretching it enough so that choke doesn't go off fully. The fuel tap is vacuum operated and it is possible a holed diaphragm can let fuel down the vacuum tube and into the manifold without going through the carb at all. Remove the vacuum tube and, if fuel runs out, you have a faulty tap. Other possibilities are sunk float, wrong jets fitted, or incorrect assembly of carb. All these are more likely than an electrical fault. A misfire caused by an ignition fault can cause the plug to look sooty, but like your Suzuki dealer implied, unlikely.
