Here’s a heads up for you. Your B-12 chemtool carb cleaner aerosol makes a terrific gasket remover. I used it to remove difficult baked on gaskets from a   2004 Yamaha grizzly 660. It helps blade cut better. You may not get it off completely the first pass but it will come off much easier. Also a shearing action with the blade will help prevent gouging. Lastly, two hands for beginners. Hope this helps
