suzuki dt 4 will not idle

[pjb123]

she will not idle and tried to die when u rev it up jiggling choke helps to overcome weak spot

stripped and cleaned carb with airline
checked theres enough fuel to carb masses of fuel
compression check 115 psi
starts real easy and will rev up with jiggling choke and throttle
but wants to die all the time on low revs
like a jet is bloked so blasted compressed air in every hole i could see
no difference
played with idle mixture screw all the way in and out no difference
played with float height no difference
i cannot see any kind of idle jet to clean in float bowl
cleaned one on top
how does idle revs work on this ...
will run at higher revs without too much problem sometimes with a little choke on ..
it seems its all about weak mixture at low revs
the screw on side of float bowl seems to be a drain as openig it just lets fuel out
anyone undterstand this csarb ====its got a pipe running through the middle of carb whats that for ..
even reduced gap in spark plug no difference
i am beggining to suspect crank seals ....
any ideas thanks in advance

Re: suzuki dt 4 will not idle

played with idle screw no difference?, take carb off and clean, your idle curcuit is plugged, screw should make a big difference, this is general info, not for your specific carb. had many old motors same problem, have to take apart and clean, blowing air with it together won"t help, been there done that.
