Tick Over Screw....Killed Engine

Not being a carb guru can i ask the question...if I adjusted my tickover too low via the carb tickover knurled knob would this cause the bike not to start ?....rode 30k down the lanes without any issues, on way home came to a set of lights and tickover sounded a bit fast, reached down and tweaked it in slightly about 1/2 turn and bike died...doh then she wouldn't start wouldn't even bump.....pulled plug and was dry....tipped bike and fuel came out of overflow pipe....so fuel in there ?.
Anyway I un-screwed it slightly and left her 5 mins and then she started back up...knocked her off again and started first kick...back to normal.
Does the adjuster screw actual shut of fuel to the I'm guessing this bit the slow running jet hence she wouldn't start ?.

No.

Love the detail you go into....your level of understanding of the problem astounds me and I might need to get you to explain it in more "Simple" terms so I can make sense of the problem

Don't think the tickover screw does anything other than raise the slide.
However I do know when I adjusted my tickover screw by mistake my bike would not start until I gave it the merest hint of throttle.
Once the tickover screw was reset the bike started no problem.
I made sure I left it alone after that.

Top man Hew, sounds like you did the same as me or I did the same as you lol.....was strange the bike was just dead wouldn't even bump but maybe the tickover screw being set to slow causes this problem.....I shall leave it alone in future specially when sitting at traffic lights........................NOOOOOOOOOOOOOOOOOOOOO

Hey Hew, he asked me????
LOL  
The slide-srew only adjusts the size of the throat of the venturi, and 'too little' is too little for starting - however good enough to idle on, as a running engine produces way more vacuum than a kicker ever can.
The idling micture-screw determines the quality of the mix, this independent (not entirely true but good enough) of the venturi's size.... so completely separate things these two.
For starting I always turn it up, then after warming up I turn it down again - that is if I can reach it, some tanks prevent access.

Too late Burp harms done I booked my bike in for a rebuild based on your short first answer, dealership recon's £980 for the strip, check and rebuild...but honest m8 don't feel to bad about it I am sure the wife and kids can survive on very little food till the bills paid.

  - you guys crack me up! I love this forum  

I think we all did the " oh i am going to adjust my iddle " thing  
I have lowered mine once because it "felt" little bit high but then the bike refused to start and had to rise the iddle little to get it start again , some people do this al the time , they drop the iddle after the engine is fully warmed up that it idles nice and low and then later after the bike got cold they rise the iddle before they start the engine , i have chosen the other path called the " lazy one ", i left it to iddle bit higher at all times and never had to touch it again  

Well Maddert,
I first like a low idel, but also a low idle setting (on a carb, diff with efi) increases engine braking - and that bit's also nice to have.


I am now sitting with a terrible guilt complex Mauser, really, I'm veryvery close to sending an Aid parcel to Blighty.
This darn helpful Hew, I feel like blaming him but can't & won't go that far, he helped me too you see.
Mind, a more practical solution than sending a box will be that I will go dine out only 3 times this week, so I'll sortof be participating in our starving bit.
