Hello all I’m new here yes I’m a first timer lol I’m hoping someone can help out I purchased a rally 200 it turns over good but won’t start I have good spark, it’s getting gas and air. I think the valves aren’t in spec but I can’t find the timing marks anywhere. Does anyone know where the marks are? Also I sprayed some carb cleaning and I got flames actual fire coming out the cylinder head through the carb what would cause this issue Thank you very much
