Frequently Asked Questions
What happens if I run without a filter?
Even a short run pulls grit straight into the carburetor and bores; never run the engine with the airbox open.
Does a dirty filter really cost me economy?
Yes - a clogged element richens the mixture and softens throttle response, so a fresh filter often brings the economy back.
Should I check the airbox for anything else?
Look for mouse nests and oil in the box - these trucks sit, and a fouled box undoes the fresh filter.
