Excuse my ignorance. I've been rebuilding my engine this summer (as you may have seen the pics back in July) and as I work I've been looking for other parts to change to help boost power. A couple things I am considering are new reeds and K&N filters. I came across a carburetor compensator in a royal distributing cateloge on page 245. My question is would adding a compensator eliminate the need for me to rejet my carbs for the new reeds and filters? If I still have to rejet I know I watch for piston wash and read the plugs, but how long do you need to run the engine before you get an accurate reading from the pistons and plugs?
