Lightly seat both screws then open each of them one and one half turns. This is the factory setting for Japanese bikes. Clean the air filter, install a new spark plug, I assume the Sym has a two stroke engine, mix the gas ans oil 32 to 1. That equals 4 ounces of two stroke engine oil per gallon of gas. NEVER use motor oil, only two stroke engine oil. Also, tighten all carb fittings such as mount bolts and clamps. Replace any rubber fittings if you see cracks. A cracked manifold will let air into the mixture which leans the mix and makes the idle rev upward.
