Thanks

I tried all kinds of stuff to mine, but it only ran much better after I pulled the head and cylinder and cleaned all the carbon out of the ports and from the top of the piston... Hope that helps.

I'm just browsing and looking for some nice pictures of a red qt50 (used to have one back in the day) but I can help you with your search for more power. First pull the head and cylinder and clean all the carbon as mentioned earlier. It also helps to use a good sparkplug. I enlarged the intake air horn on the carb and radiused all the hard edges inside it...then followed that up with a full polish on the inside of the carb. You can pick up a lot of power by smoothing out the little intake pipe between the reed valve and carb...You need to use a die grider or dremel with a long carbide bit. I enlarged and contoured the ports in the cylinder, and also milled the head for some more compression. You can add a k and n filter to the carb if you get rid of the stock side covers over the air filter housing. If you want to know more just email me at matpei@yahoo.com
