Status: offline 		You can solder the hole shut (I would remove the choke plate from the shaft first ,and be sure to put some loctite on the screw when you put it back).
The cause of the problem is probably the carb diaghram.
You should not need to close the hole in the choke if the diaghram (fuel pump) ,is working correctly.
Put a carb kit in it and be sure to replace the diaghrams and clean or replace the internal screen while your in there.
K20 WAT is the kit number - many sources on ebay

One other item to check is the pulse line they get hard and leak at times and won't pump properly. Of course there is always the internal carb issues, a dirty screen can also cause this. But I would do the simple stuff to start off with.

Status: offline 		hey guys i didnt mention this is a new engine. this is the 3rd new dle in my club that has this issue. i agree it may be internal but seems weird all three
do the same thing. one is so bad he has to take the muffler off and squirt gas in the cylinder every time he starts it. if not ,you can flip it all day and it will never hit

Either the choke plate isn't seating (it doesn't need solder) or you have a plumbing problem.

Status: offline 		when one of my gassers has been sitting for a while regardless of brand, they all take several flips of the prop to get the carb wet.... after i get it to pop with the choke on and throttle open, it may take a few more to get it running.... thats pretty much the way it is



is this your first gasser?

 and fliping the prop 200 times to get fuel is not normal. on my new dle 55 its still on the test bench and i can duplicate this issue at will. pluging the hole works every time.
2 or 3 flips and she pops.

Plugging the hole is just a band-aid to another issue. I also agree with BH that you have an air leak someplace. The first place I would look is in the induction area. The carb/carb block/reed cage/crank case stackup is problematic with the rear carb setups. Very easy to overtighten the 2 mounting bolts and distort the plastic parts. The second place to look would be the reed block and reeds. If the reeds arent sealing well during the piston downstroke then you have a weak pulse going to the diaphram. Soldering the choke plate may get you better starts but the root issue will still leave you with poor performance and reliability.

Also, I would confirm the diaphragm is correctly installed and not hardened
A maintenance kit is cheap from you local lawn mower shop and includes different types of diaphragms, gaskets etc

It's like a different engine now.

Status: offline 		Hope you folks don't mind me butting but I have a DLE 30 with more or less the same problem. It started and ran great last year but after storing for a few months won't start. If primed it starts and runs great but no matter how many times I flip the prop I can't get it to pop. I've been reading the various forms and did replace the filter screen and looked at a rubber diaphragm on opposite side of the carb. It looks good and is flexible. I keep hearing the term "Reed Block and Pulse Line"  which could cause the problem. Where in the carb is this found, on the filter screen side or the side with the plate held on by four screws. I've tried to find a site with an exploded view of the carb without success as it would really help.

Thanks,
Rich

Your 30 doesn't have a pulse line as such. The pulse port is internal between the carb and the reed block and is just a drilled passage. The DLE 55 uses a separate external line for this function.

The reed block lives between the carb and the backplate on the engine. If you don't know where is it, I don't think I would recommend you try to work on it unless you're up for learning new things about engine maint.

For what its worth I have found the tip of the needle stuck in the seat after a lengthy storage time on three occasions at least.
Might be worth a look at beginning of the flying season.

Thanks again,
