On Zama M1 (which are used Only on Eager Beaver And Mini Mac chain saws) ther are several precautions to watch for. One is, If you ars not familiar with these type of carburetor (2 cycle in general) allyour effert of disassembling and reassembling willnot solve your problems.The need to be pressure tested,"THEY MUST HOLD PRESSURE"(by the way,that white plastic thing is called a fuel pump body).Also,the fiber washers and plastic sleeves holding the carb/coil to the crankcase,mut be in the right possition. Now you mentioned fuel coming out of the muffler. I`d suggest you take the muffer off and see what condition the piston is in . FOR COMPLETE INSTRUCTIONS,DIAGRAMS OF THE CARB AND THE ENGINE IT`S SELF, GO TO "ITERTEC.COM AND ORDER #CSS-8 CHAINSAW MANUAL." THERE`S MORE TO THESE SMALL ENGINE`S THAN WHAT MEETS THE EYE.
