I have always wondered: When we tickle our amals, the fuel spills out the tickler button or a small hole just below it. This appears to be well up into the level of the throat. It looks like this would be too much. Does the level in the bowl really reach this high or is there a passageway that just lets a little in to this height.

Jaydee,
There are two tiny holes just inboard of the needle jet from the primary pilot mixing chamber that squirts out raw fuel into the induction system manifold. The idea is that when you just see fuel from the tickler you let it go. This ensures you have fuel on the "rich side" and should start the engine with one or two kicks. There is no accelerator pump on the mrk1’s to help squirt that small amount of extra fuel. This tickler is the solution. Tickle till she squirts but don’t go overboard. On a magneto fitted twin at the back of the timing case might cause the wrong type of fireworks to happen. :shock:

Like Thomas said no need to even see weepage for the pilot 'chamber' to be filled and best sucked into engine by closed throttle on 1st kick of cold engine. That's all it should take, if all other factors normal. I've tried to count each tickler till I see slight weep then later try to just hold em for a count and let go before any weep or wetness detected - w/o looking down. Sometime I could but mostly couldn't so gave up on that little self contest. Mine don't need another tickle to start on closed throttle till many hours left to cool into night.
 
I don't have chokes on my 850, so have to tickle. In the cold weather I have realised I need to jab a tickler while its running a little till it warms or I have to start all over again, [ sometimes 5 times. ] It starts first kick normally. Its a bit of a race to get to the tickler after the first start though. Warm weather is here now so gymnastics not required so much.
Hobot, when the fuel squirts out that hole in the side, that's showing you how high the fuel is in the carb.

Steve , I have tried too, but it is impossible to routinely guess how long to hold the Tickler down so that you fill the Carb but don't leak any fuel out. The time to fill changes with the fuel level in the tank.

If it’s really quiet I can hear the fuel come to the top of the float bowl just before it squirts out at the tickler. But my ears are not that good anymore. Too many loud toys. The sins of my youth. :wink:

Ugh I guess the level of fuel in tank and temperature of the gas skews second guessing ticklers day to day. Still like the perfectly fettered Commando, we know its possible > now and then. In my shed or garage I can hear fuel flow in and get higher more juicy sound but always surprised me by some over flow. Funny ole craft we choose [or it picked us] to nurse along.
