GL1000 Float Adjustment

Post by Spullin541 » Sun Nov 26, 2017 10:16 pm



I rebuilt a set of GL1000 carbs two years ago and have done a new set this weekend.

To save my life I literally forgot how to set the floats...

I’m getting old.

The rack is help upside down to unspring the float?

Then lifted to where the tab contacts the spring loaded float needle in the seat? At 22.5 mm I have a Randakk gauge, that I used last time..

I blows my mind I can’t remember.

Its 21mm for Gl100 float height to my knowledge.
Cover the basics and the technical will follow easily.

You need to stand the carbs upright, check and adjust the top ones then turn them over do the same

Look on here NGW site. on page three then scroll down a bit

Previous mentioned .......... https://ngwclub.com/forum/viewtopic.php?t=2952 ......... phantastic DIY thread !!!

BTW....after setting of all float heights you can check with the carbs in horizontal position the real fuel levels in open end plastic tubes.......and also wheather they can keep the exact level for some reasonable time or not .......
This way makes you sure that the 4 x 21 mm float adjustment leads to the proper fuel level of each individual chamber.....

Checking the level in each of the 4 plastic tubes (communicating vessels principle)........(CLICK to enlarge pictures)
