Hello JaysNJcub127,
These carbs are easy.
Turn the fuel valve off or pinch the hose off.
Remove the air filter house.
Pull the float bowl off using a 9/16 6 point socket.
Turning away from the seat towards the front of the mower.
Use a short piece of awg12 wire to poke the float pin out, remove the float making sure not to loose the float needle
Shake the float to see if it is full of fuel.
If the float is good and you have gunk in the bowl.
Un-screw the vertical screw-adjuster and take it out.
It is about 2.5 inches long with a sharp point.
Look at the carb the cast tower that extends into the bottom of the bowl
has 2 holes in it. Use a piece of light wire to poke through 1 hole and out the 2nd hole. This is where the main part of the carb gets it's fuel and when these two holes get clogged.. NO Fuel gets to the mains.
A shot of carb cleaner works good after using the wire.
Inside the tower is a needle seat jet. It can be removed with a flat screwdriver, but is not usually done as it comonly sticks and won't come out anyway.
The 2.5 inch long needle has 4 holes in it make sure these are clear and use carb spray to spray into the two bottom holes and spray comes out the top holes
That is pretty much it.
Re assemble.
Using only your fingers tighten the long needle all the way down and then using a screwdriver back the needle out 1 1/2 turns.
Never force the needles with any tool as you will ruin the factory "TUNE"
I may??? If I get my 105 running, convert it to E85 just for the fun of it...
Feel free to contact me if you have any questions...
I love Tuning Carbs!!!!
