recently serviced my single AMAL 930 from '73 TR7RV, flattened the bowl and added new upgraded float and needle. Bike runs perfect but when I pushed tickler down no gas came out, kept holding it down and gas eventually came out the intake of carb.? There is a slot in the tickler when looking at it with bowl removed, could the orientation of this cause the problem?

Probably when you changed the float you changed the height of the floast relative to the tickler. Remove the float bowl and press doown on the tickler button. Using a pair of side cutters, grasp the roll pin (the part that pushes on the float) near the carb body and *gently* lever it away from the tickler button a bit. This will lengthen the reach of the roll pin realative to the float.

Use the flat side of the side cutters as a fulcrum against the carb body to ease out the roll pin. Lever it gently, or you'll end up pulling the roll pin out of the tickler button sleeve and the tickler button and spring will launch across the garage!

Thanks, so even though the tickler is flooding out the carb since gas will eventually leak from intake if I hold it down long enough, it's still not long enough to go through tickler itself?

I screwed a self tapper into the bottom of the roll pin, screw in or out to adjust.

Cort, didn't see that other part of your post. If you have gas flooding the bowl and carb, then you should be good to go. In theory, the further the roll pin sticks out of the bottom of the carb when tickler is depressed, the quicker the bowl should flood with fuel.

As to why the fuel is not exiting the tickler assembly, you must have the only dry-tickle Concentric in existence! crazy

I have a "dry" tickler also. I do not know what makes that way. Tight fit?

It's been a while, but I seem to recall inserting a slim pin punch into the roll pin. Then with a short sharp tap from small hammer, that was enough to move the tickler button. A millimeter at a time or so, till you get the required float deflection. This would have been with the early small steel tickler button though I'm assuming it would do for the later larger alloy buttons as well.
The whole thing is quite sensitive as to position and with any adjustment to float level, the tickler setting could well need adjusting to suit.
Hope this helps.

You didn't put the floatbowl back on the wrong way round after the service did you?
