How to remove #24 Main Jet Tube?
« on: April 10, 2023, 02:45:37 PM »
How do you remove #24 the Main Jet Tube from the carb so the new one can be installed?
I assume that they are pressed in???
So that brings me to the next question... How to press in the new one?
TIA

It is not really a very tight interference fit.  Hope you like oriental food, cuz your gonna need a chopstick!  First remove everything in the float bowl, most importantly the main jet (26) and emulsion tube (25).  Next unscrew the top and remove the whole slide assembly.  Now take your chopstick through the open top and push your needle jet (24) out through the float bowl.  Probably gonna be fairly stuck if you have never removed it so only use as much force as necessary with a tool softer than brass...liike a chopstick!
If it works good, it looks good...

I have never seen one of those needing replacement unless a ham fisted PO mangled the top of the open end inside the carb body when trying to remove it. They will sometimes just drop out if you have used a Ultrasonic cleaner on the carb bodies.

When they don't I would spray some cleaner down in there and then I always use a conical pencil less the lead piece. It will fit into the opening in the top section inside the carb and a light tap will dislodge it to allow it to come down the tower assembly in the float bowl area.

The wooden pencil will not damage the brass and there is really nothing too special about the piece. Just remember it goes back in with the open top facing into the carb venturi area. The closed over bottom faces towards the float bowl.
Common sense.....isn't so common!
