A little update. Today the Honda would only run with the choke open. So I decided to pull the bowl. Mind you it’s 14 years old. There was a bunch of crud. Power foamed it and wiped it as good as I could. Shot more power foam into bowl after installing. It’s running smooth now.
Since my plugs get changed every 30K on my Tacoma. I clean the throttle body as well. I don’t remove it. With the truck on I wedge a pole between the gas pedal and seat to open the throttle body. I use Amsoil power foam and wipe away.
Yeah this thing has been a beast. I did a few years ago. Filled the cylinder with Amsoil power foam. Let it sit over night. Pulled the cord a few times before installing the plug. I should taken after photos of the piston top. It did clean most of the carbon off.
