hello .
Is somebody running in to this next problem?
new dle 111 after a lot of days trying to start the engine, find out that he starts with no problems when mounted carburator up right.
But as soon I mount him back in the Plane with carburator down (as shoot be) He will not start only on the choke a vieuw pufs and a lot of benzine leaking.
Is this a benzine intake problem or what shel I look for.
Thanks for advice.

If your choke plate has a hole in it, solder it closed. Make sure the choke plate is closing completely. The trouble is trying to make liquid run uphill, needs a strong vacuum. Good luck, red

If the carburetor is on top and the engine runs that way, it's pumping fuel "uphill" fine. Right? If the carburetor is on the bottom and the engine won't start, and fuel leaks from the carburetor, then it's pumping "downhill" and also getting a siphon effect too? Sounds to me like its flooding out due to fuel siphoning down to the carburetor and having the choke on too. When it won't start and the fuel is dripping, pull a spark plug and see if it's soaking wet. If it is, might want to clear the cylinders out and get the raw fuel out of the crankcase. Start the engine upright, run it up and clear it out good and set the plane right side up and see if the engine continues to run properly. If it sputters and coughs and quits, it's getting too much fuel. I'd be looking at fuel tank height, and the regulator/pump assembly to ensure those parts are working properly. But that's what I would do. YMMV.

The needle of the metering valve in the carb is not seating.

Thanks for advice, but my carb has no hole in the choke plate.

Thans for advice.
Motor keeps running when placed plane on the ground, but will not start again.
Still problem with leaking fuel,I have a frend flying with the same engine and he hase no problem at all.

Tahk you for advice.
the supplier say the same only thing is he lives in Belgium 3000km away.
I will see if I can find a manuel for this carb and clean him in site and then look if this will have a good effect.

It may just have some trash stuck in it?

When starting the engine, if you can, put your finger over the carb opening. BTW, did you pull a plug after a few start attempts? What was plug condition? Good luck, red

This would be quite a dangerous feat with a 27" prop. Not what I would suggest doing. The actual problem here is that the metering needle is not seating. It's the same thing that used to happen with carbureted cars when the float would stick in the down position. When raw fuel is dripping out the carb in large droplets there is not enough vacuum in the reed cage to draw the fuel up into the case. What makes matters worse is that the low needle has now been adjusted for a leaking carb and is now set too lean. The fix is to pull the diaphragm cover off, pull the metering needle and fork out. Spray carb cleaner through all passages and put the needle/fork back in. There are many videos on YouTube that show the correct adjustment of the metering lever/fork. Open the low needle back to where it was originally and fire her up.

make sure the diaphragm is in the fork on the needle arm some times they come from the factory mis installed and holds the needle seat open.

Good point! I have seen 100cc carbs without the grooved pin on the diaphragm. All depends on which Walbro DLE copied. But you are 100% correct, if it does have this type of engagement and it is not done correctly then it's going to leak like crazy.

I have taken the carb from the engine, dis assemble it and wat do i find? yes the needle is not in the fork.
But when taking it apart not one of the packings ar in one piece.
So i have ordered a new replacement set, and will montage after cleaning the carburetor.
Hope this will solf the problem.
but in the mean time we have snow over here so flying seison is over.
Do a update if the asembling is complete and if the engine will work like it must be.
But this will take a while.
thanks you all for your reactions.

Update.
Have placed a new carb, and motor runs whitout any problems.
