a flooded carburetor will spill fuel into the combustion chamber causing an improper fuel to air mixture. too much fuel in the combustion chamber will not completely burn. the unburned fuel will be pushed out of the exhaust.
A carburetor flooding with fuel can result from several issues. A stuck float in the float chamber can prevent proper fuel regulation, allowing too much fuel to enter the carburetor. Additionally, a malfunctioning needle and seat assembly may fail to seal properly, causing excessive fuel flow. Lastly, a clogged fuel line or filter can lead to pressure buildup, contributing to flooding.
You can smell exhaust because your exhaust pipes and exhaust system has worn out. As a result, the exhaust and carbon monoxide it contains leaks inside the van. Soon, it will not be a problem because the carbon monoxide will have killed all of you.
Backfiring in a Honda 400EX when you let off the throttle is often caused by an overly rich fuel mixture, which can result from a dirty air filter, incorrect carburetor settings, or an exhaust leak. Additionally, it may be due to unburned fuel igniting in the exhaust system. Check the carburetor and adjust the air-fuel mixture, and inspect the exhaust for any leaks to resolve the issue. Regular maintenance can help prevent this problem from occurring.

Flames coming out the exhaust is the result of the exhaust igniting fuel that was not burned inside the engine. Occasional pops of flame can be from backfiring, which shoots out unbirned gas that gets ignited from the heat of the exhaust. On cars without electroinc ignition or fuel injection, which covers all older cars, turning the ignition off while moving and then back on can result in a backfire and flames.
A popping sound coming from the carburetor typically indicates an issue with the air-fuel mixture, often due to a lean condition where there isn’t enough fuel for combustion. This can result from a clogged jet, vacuum leaks, or incorrect tuning. Additionally, backfiring through the carburetor may occur if there's a timing issue or if the ignition system is malfunctioning. It's essential to diagnose the root cause to prevent potential engine damage.
flooding
Any oil burning will result in "blue" smoke. If you have blue smoke coming out of your exhaust, you definitely have an engine problem
Couple things. 1- worn valve seals letting oil in the combustion chamber. 2- worn piston rings -same result. You probably have a cracked head on the exhaust port.

Ireland has many rivers and lakes and can get a high amount of rainfall. As a result flooding does often happen in parts of Ireland.
The usual result is flooding.
