And I decided it needed a tune up anyways. So I replaced the spark plug, air and fuel filter, fuel lines. I cleaned the spark arrestor and rebuilt the carburetor. Which solved my problem. It starts and runs on choke but eventually dies same goes when I take it off the choke. I also can’t run it at full throttle. I did this 3 times and now it’s back to not even starting but it may be flooded too so. I’ll open the carburetor later. But my last thought is it might be the ignition coil/wire but I want to be sure before I replace it. So if anyone has any advise that would be much appreciated, thank you in advance.

Just putting in a rebuild kit without first cleaning is one mistake. Then when replace the metering lever its height must be set correctly, metering diaphragm and gasket must installed in the correct order, and finally the carburetor must be re-tuned most times. Then of course the compression should have been tested before even getting to the carburetor as if the engine compression is below 100 psi it is a lost cause usually as the PNC would need replacing but the piston is already NLA.
