If you notice poor performance coming from your motor or any leaks near the carburetor, it would be worth inspecting and potentially replacing the gaskets to any other parts being damaged as well. To replace this gasket set, you will first need to disconnect the spark plug, and then the fuel line of the engine. Locate the carburetor and use a wrench to loosen and remove the carburetor bowl. Once the bowl is removed, carefully remove each gasket and O-ring that is worn out and clean the carburetor with carburetor or brake cleaner. Install the new O-rings, and ensure the new gaskets have gasket sealant to prevent leaks. Reinstall the carburetor bowl and secure it with its screw. Install the fuel line and the spark plug, and check the engine for any leaks.

Like I said, this engine was way too lean from the factory. Being a honda clone engine, I was pretty sure honda carb jets would fit, I was right. A simple matter of removing the carb bowl and unscrewing the jet and installing the jet of your choice. The too lean factory jet was a 103. I ordered a 105 and a 108 to have options, I installed the 108 and it is perfect. The engine starts on the first pull, runs smooth and I can adjust the idle as low as I want to and it stays smooth. The exhaust is cooler and the exhaust even has a quieter note to it. This engine should last a long time now. On to the next projects. I ported the exhaust can on my husky chainsaw yesterday, and it definitely has more power now. Life is short, just do it!
