DIY Float Height Tool
« on: August 21, 2007, 08:55:25 am »
A Honda shop wanted an outrageous $40 + tax for the tool.  Here is my 1c solution.

The tool fits nicely between the bowls and works like a charm!

1.  Split the old diskette case and remove innards
2.  Measure precisely the float height you need (shown is 26 mm ) and  mark with the X-acto knife
3.  Cut out the height section and a second smaller piece for main jet clearance.
4.  Trim top off (or not)
5.  Label your tool
6.  Make as many as you need.  Trade them with your friends.  Comes in many colurs  :D

I did the same, but with a piece of cardboard. I like yours; lets see if I still keep some floppy disks around...

Used bristle cardboard for my first one.  the legs got creased and bendy, and the carb bowl edge puts little dimples in them, so, the height changes - was good for only one use.  The plastic version doesn't have any of those issues.

I didn't bother to make a better version because I knew next time that I would need it, it would take less to make a new one than to find the gauge in the drawer chest.... but I have to admit the floppy disk gauge is the perfect blend between durability and low cost.

I made a similar device but out of 0.040" aluminum.  The overall size is smaller so it will fit in and check the float heights with the carbs on the bike.

Perfect and thanks for sharing.  I am making one today.  Can I use this even with the carbs on the bike just to check the height?

The book says to do it with the carbs off of the bike, upside down.  I have gotten away with doing it with the carbs on the bike.

Bump on the pic repost request.
I've seen these made out of credit cards, but never a floppy disk, and now I'm super curious.

nowadays you'll have to check yard sales to find a diskette!

You know all those credit card offers you get with the fake credit card they enclose to make you want it??  That's my 22mm float height tool.  Flexible, yet durable plastic, and free.  Great minds...

Cheers,
G
