Well I had no issues going back and clicking on the pics that I checked before posting that, so I'm not sure which ones are missing.

Edit: Ok, just went and checked again, and now I can't click on the little thing from photobucket, but I could when I posted originally. Ran into this issue on a couple other forums and it works fine there, not sure what's up here.

Mmmm pics on thread states:
(photobucket)
Please update your account to enable 3rd party hosting.

But was able to open by right click on mouse.

Now, from what I understand, it's just about flattening the reed cage seating and ...voila !

Woooww engine really performs much better now, for those who have not done this mod yet... go ahead its worth .

It really sucks you can’t view the pics on this topic. I assume the OP is long gone and their Photobucket account is closed.

Is there anyone else who could do another post on this topic with pics, please?

for some reasons the pics don't load for me..any way i can get them?

try going to thread tools on this page, upper right corner, and then click see attachments. let me know if this works for you to see some pictures. if Not complete, let me know,

This was done after about 500 flights and two seasons of flying. This engine ran great before the mod, but now it's my $320 DA-55. I did not change over to bowman rings because I showed no signs of blow-by. I will however put them in a brand new engine and do this mod before even firing the engine for the first time.

Order a new gasket set before doing the mod! Mine were ok and reusable but they are $3.99, not worth the risk IMO. I also sanded the carb smooth. You have to remove the choke plate to do this, just the plate, not the entire arm.

ENJOY! Ask me any questions!


So you have a dle 55? Lets make it run like a DA.



Remove these two bolts. And take note of the orientation of the reed block, and port location that goes to the carb.



Thats a slap of marble I had laying around. 320 wet sand paper on the left and 400 on the right for finishing.



Reed Block Before. Clean them on the outside first, then mark so that you place them back exactly as they were before.



Clean up these edges using a file. Notice they aren't even square.



Mark with a marker. It may look flat but the results will fool you.



Notice the low spot. Keep sanding.


Very light pressure and keep it strait on the edge. Take your time!


This was actually the furthest off. This is what it looks like after. As soon as you begin sanding, you will see the low spots. I took extra care with the 400 grit paper after the low spots were gone.

This video does the mod no justice. The true test and change is in the air. No more blurbling the entire flight. It now runs smooth throughout the power band, and throttle response has been greatly improved. ALSO before anyone brings it up... I lowered the throttle in the video to see how low I could go. This is NOT the engine loading up.
