I can’t pretend to fully understand the way carburetors work. I only know as much as I can interpret from what I read online and from that cryptic Clymer manual.

All my hunting through forums for a step by step instruction set for rejetting carbs was fruitless.

Here is my photo set that hopefully will help others feel less timid when it comes to opening these guys up. Granted, I didn’t fully disassemble them, I only replaced the main jets.

Removing the leaf spring is as easy as moving it to the right and sliding it out from the main jet.

Keeping everything together.

Since I was in here I thought I may as well check the slow jets to see if they were dirty or clogged.

They were fine. I blew some canned air through them and inspected them thoroughly.

Shiny new main jets. Installing them is as simple as pushing them in.

That’s it. I checked all the slow jets (all clean) and pushed in the new 115 main jets, and placed the leaf springs back on.

….but

When I was putting the float bowls back on I noticed that three screws on two carbs weren’t screwing in correctly. The screw holes on the two carbs were stripped.

I was a little sad.

If the screws had been stripped I could have easily replaced them, but it was the screw holes on the carbs that were stripped. Bummer.

Luckily, I live fairly close to an Ace Hardware. A quick trip, and ten minutes later, I came back home with some sweet looking allen bolts.

That solved my problem, except this method only worked on the outside carbs on the outside corners. I just lucked out that those were the holes that were stripped.

I have to say that I kinda enjoy running into these small little problems. It makes the whole experience that much more fun.
