Given my talent for misunderstanding charts, I rely on the chatter to pretend I know what I'm buying. It hasn't helped my photography much.

My buddy Jake was hauling freight through Nevada last summer. The dust out there coated his diesel engine so thick his truck started choking near Reno. He had to get towed because his air filter was totally blocked and he didn't have a backup. After that mess, he actually took advice like @rowan_kim55 mentioned and now checks his filter every other time he gets fuel. He even bought one of those heavier duty filter elements and keeps a spare in the cab. It really shows how you gotta stay on top of it in the desert or you're stuck on the side of the road.

Man, my buddy had the exact same problem. Some guy at the scrap yard finally told him about preheat and it fixed everything.

Remember my friend who sketched goofy animals on all his old work schematics? His new hires found a box of them in the storage room last year. They said those drawings actually helped them understand the flow better than the clean digital copies. It's like the doodles added context, made it stick in their heads. So maybe those mustache comics are more useful than we think.

Seriously, patch testing saves so much hassle with DIY fixes.
