I cannot hear your tractor from here but this is what I will tell you from your explanation. A burned or leaking exhaust valve will rap in the exhaust. A leaking intake valve will mess up the intake to all cylinders and can cause popping back in carburetor. A bent push rod or anything that prevents the exhaust valve from opening fully will cause a pop back into carburetor. How it works is on the compression stroke it build pressure in cylinder but because exhaust does not open when it should the compression in cylinder is then released back into the intake side when intake valve opens. This happed a lot on the 400 series diesel engines when they were first released due to a poor rocker arm that would fail and not open one of the EXHAUST valves. A compression test would confirm leaking valve or better yet a cylinder leak down test. You can usually hear a valve leakage problem by reving engine wide open, shut switch off and listen to intake and exhaust while engine is coasting to a stop. You can also hear compression loss by grounding coil wire and cranking engine listening for unevenness in speed.
