Triumph Bonneville T120R Setting the float levels

I get a miss fire at around 5000 rpm as the motor is running rich, I check the float heights, they are not done in the usual method of bending the tangs on floats. The floats are set and adjustment is acquired by repositioning the needle seat. This is a guide to setting the float level for an Amal 930 carburetor,with the standard settings near the end.
After doing the job she runs a hole lot sweeter! :-D

Thanks Joe :-) it will make a big difference when the carbs are set up,

don't forget to sync the cables (slides)

let us know how you got on!

hey, great videos man! you've helped me so much with my '71 bonnie! question: i recently did a full cleaning of my carbs and set the floats. now left carb doesn't flood when i tickle it. is it possible i set the float too low?

when pressing on the tabs when should i stop pressing? when the pin goes into the hole, there is a little room left for me keep pushing down. should i stop right when the pin gets seated? if so, i can definitely see how i would have set the float level a little too low.

Hi bja214 :-)

glad my vids are helping.

You should press lightly on the float when the tangs are at the bottom of slot thats enough.

I extended my tickle buttons using a small (cut down) nail, what fit in the roll-pin.

Thanx for this video Lunmad! Really helpful on this topic. I didn't really understand what people meant when they explained this process to me. I put it in one of my playlists so I can find it again when this particular step comes up!

...hello Lunmad, I tell ya that I did the opossite way in my 626. I did what say in some manuals, to heat the bowl and the hit the other way (from down side), so I have that brass thingy more "tall" right now

Wouldn't it make more sense to measure the gap while pressing on the actual needle, not the float flange? It seems more important that the needle range is addressed instead of the float range. I have my float at the acceptable level when up, but I believe this is too low for the tickler to even contact the float and she will hardly run on that cylinder. Perhaps my floats have gotten misshapen?

Thanks,
