CRF110 Carburetor Cleaning and adjustment

I watched a couple YT videos the other night and decided that I could tackle cleaning my daughter's carburetor. First I had to get to the store to try and find a JIS screwdriver (or bit). I luckily may have found a suitable bit- I looks right and there are plenty in the little $8 kit to choose from, so I had a go at it.

I decided to take off all the bodywork to get better access. I know how to do it easier next time.

I drained all the fuel. It wasn't bad, I think I can reuse it. The air filter looks clean too. I should check the spark plug and motor oil (I'll do those tomorrow).

After removing the carb and cleaning the jets (some holes near the tip weren't passing light as I thought they should) I thought it wasn't so bad. I hope that soaking in carb cleaner was enough as I didn't have anything small enough to poke in the needle openings.

All was going well until it was time to put the float bowl back on and I noticed that the gasket seemed to have stretched a little.

Here's a pic of the gasket and the offending (?) chemical I used.

Re: CRF110 Carburetor Cleaning and adjustment

Pro tip when cleaning carbs in solvent.

Always remove o-rings and gaskets. O-rings are always a gamble whether or not theyíll swell from the chemicals. Sometimes the fuel/air screw will have an o-ring on it too.

And always have a spare rebuild kit on hand, easy when itís only a single cylinder.

Re: CRF110 Carburetor Cleaning and adjustment

The microfiche also reveals an o ring that I didn’t remove and it’s an expensive little booger. Should I also purchased that too and replace it anyway considering how the other appeared?

Re: CRF110 Carburetor Cleaning and adjustment

Also, there was an extra nipple and tube on this carb that I can’t identify. I’ve got fuel, air intake, mixture down tube and float bowl drain. What’s the other for? Appears to be for air but for what I don’t know (didn’t trace it last night).

Re: CRF110 Carburetor Cleaning and adjustment

Also, can I use a gasket maker instead of replacing the rubber gasket?

Re: CRF110 Carburetor Cleaning and adjustment

I talked with a trusted dirtbike mechanic who told me about a gasket in the freezer trick that can sometimes work. I'll give that a shot.

I sent him a link to this thread and he got excited when seeing the can of Gum Cutter and cautioned against using it in the future. He said he recommends Brake Kleen (I think that's a brand name) as it's gentler on parts that Gum Cutter. I'll probably toss the GC in the trash or return to the store if they'll take it back.

Got a pic of it? Probably the float overflow drain.

I would say no. Are you talking like a liquid type stuff? Iíve never had to use a ďmakerĒ, but I have made gaskets out of sheet material for automotive applications. Iím a firm believer in using OEM stuff for motorcycle replacement, aspecially on carbs.

Re: CRF110 Carburetor Cleaning and adjustment

The "mystery" hose is a vent.

Today I called the local Honda dealer and inquired and they quoted a price of $32.xx for the full kit.

I think he was mistaken as I got it from their online store for $13.55. It will be shipped to the store and I'll pick it up...whenever.

Then I arrive home to try the freezer trick and notice that the gasket had shrunk noticeably in my cold garage and I was able to get the float bowl back on!

Should be smooth sailing from here!

I'll have to make a decision about using the same fuel vs tossing it out. BobVila.com indicates that the fuel is probably good and I hope so, I've got a few gallons of fuel spread out in 3 containers (2-stroke premix, 87 and 93 octane).

Re: CRF110 Carburetor Cleaning and adjustment

Happy to report that the bike is running great! I ran it with some "fresh" fuel and 3/4 of the old fuel, which had a slight yellow/brown tint because.....wait for it.....
I put Stabil in the tank (Doh!)
I was also able to solve the original problem which was a too fast idle. I simply needed to turn the idle adjustment screw. Leave it to me to find the complex reason when the answer is simple.
