The bike is 19 years old. Caseings will be VERY hard to find. Suggestion; take the case to a welding shop and ask them to weld the crack. Teey will have a MIG or TIG welder which will do the job and the cost should only be about 20 bucks.

Assuming you are using two stroke engine oil, the pump is pumping too much into the gas. DO NOT use motor oil in the gas. If 2 stroke oil is being used, then get a new pump, fix the one you have or disconnect the pump and mix the oil with gas when you fill up. Four ounces of 2 stroke oil per gallon of gas equals the standard 32/1 fuel mix.
