There's also a variation as to whats included with the Walbro kits from Stens and those from Walbro themselves

This is a Sten's kit for the WT series Walbros. It comes with the teflon(?) diaphragm.

For what it is worth, I rebuilt a WT201 on a ZDZ 50. Replaced the main screen, both diaphragms, and cleaned everything up very well. The metering lever was out of adjustment, lean, in a never-opened carb. That was reset. The engine now draws fuel better than it ever has. And, the infamous "It's a ZDZ and hard to start" no longer applies. The engine was also much easier to tune with the re-built carb.

It is impossible to know just what change made such a noticeable improvement in the engine. My experience with gassers is limited to this engine. I have a new-in-box ZDZ50 about to go into a Wild Hare Giles; the carb on that engine is going to be inspected internally and have the diaphragms replaced before it is even mounted.

Mine runs good everywhere except inverted after about 10 or 15 seconds. If I throttle back, roll over and let it idle a few seconds sometimes it will throttle back up. It also doesnt want to throttle up after a downline. Has about a gallon and a half through it and CM6 plug. I'm going to tear the carb down and check it, but is this usually a sign of too rich or lean on high or low? Thanks

Had a good afternoon flying the Giles 202 with a DLE30. I got to see and touch my first DLE20. Larry bought 3 of them. Man what a cute compact engine. Yesterday was nice too and engine related. I took 2 engine,s too a Old Time Tractor, Auto and engine show. Even steam engines running a wood cutting mill. I added 2 photos. Best Regards Capt,n

prophecy; the following is from 2 Stroke Engine Tuning Technique by Pat Roy aka Tired Old Man "Sags on a long up line? Take a little off the high needle. Really fat and burbling in mid throttle level flight? Adjust the low a little leaner. Very small adjustments on either needle for flight adjustments."
