OMC Cobra 4.2L Very difficult starting when cold. Once the engine is warm starts immediately. I'ved replaced points, plugs, dist cap and plug wires. Choke appears to be working.

Cobra hard starting

Pump the throttle a couple times but leave it out of gear when you try to start the motor. Push the throttle forward about a third or two thirds then try to start the motor. Watch your rpm so it does not run away from you.
I have a General Motors in-line four-cylinder Marine engine and that's how I start mine when it is cold or hot outside. If you have electric choke make sure the butterfly on the carburetor isn't open to far or it will not suck enough gas to start. When the engine does start it may shake some until it burns off that extra raw gas and your combustion increases. The engine shaking does not mean it is misfiring.
