first you should know I am a veggie... 100% right into the fuel tank...

Your injectors are probably fouled by the veggie.....

Go down to pep boys or auto zone and get some parts cleaner. It comes in a paint can and has a little basket inside. Then soak those injectors for a couple of days.... start yourself a rotation. remove an injector and replace it with a spare and soak it for a while. I would even disasseble those and soak them.

Your cylinder sleeve, pistons and rings also look like those injectors.... I use
Diablo carbon remover.... (its used in industral kitchens) I remove the injector and fill the piston and let it soak over night. Then I vacuum the carbon remover out. Then rinse the cylinder with oil...or diesel... or kerosene. or transmission fluid.... rinse it a few times... then change the motor oil.... turn it over a few times and rinse it out real well....Do a cylinder each oil change.

They actually make cameras to look into cylinders... you may want to see inside....

I thougth the second fuel tank was suppose to protect you form carbon..
