    Need to check behind the carbs on the intake manifolds to see if you have brown gaskets. If you have black gaskets, these need to be changed along with other parts. The early models had issues with the gaskets swelling and making the engine (pass out) on take off and hard to start. The very first thing to do is run compression, if you have off compression, you have other problems. The engine should be around the 95-100 psi range. be aware that all compression gauges differ from one to the other. So long as the cylinders are within about 10-15 psi of each other.
