Hi Michael,

After I installed the flange around the intake tube, I placed the O-ring in first, and then the retaining metal ring on top of the o-ring. I then pushed down on the metal ring to make it flush with the top of the flange and o-ring.







This made installation pretty easy, as it all wanted to stay together.

Copy all. If you don't mind doing an experiment, try installing the O ring on the inner retainer first, then set it aside. Install the two bolts to hang the tube (big gap), then slip the O ring assembly in and draw the bolts up. Please report back with relative observations.

I have a set on order for the Rocket so it will be a while before I can try "your" method to compare.

I use Mike's method as well, O-ring installed over inner ring, put bolts in a few threads, drop the O-ring and inner ring into the recess while holding the tube down, do up the bolts.

There is an arc cut into the face of the silver ring to aid in keeping the O-ring in place.

Good thing is once you get the bolts tight, you should never have to touch this stuff again.

BTW, we shipped out a bunch more today and some more will go out tomorrow to those who ordered and paid.

Another CNC run is scheduled for June 27th.

Michael - I tried your method, but I couldn't assure that the inner metal retained ring wouldn't slip out. The only way I could assure all of the parts were oriented correctly was by using my original method.

I did run into a frustrating situation on my #1 cylinder where the flange would want to slide down the intake tube while trying to get my screws aligned, causing the o-ring and metal ring to fall out. This was quickly remedied by using some electrical tape to hold the flange as high as possible during assembly.





I finished installing everything on Friday and went up for a test flight. Without exaggeration, THIS IS THE SMOOTHEST MY ENGINE HAS EVER RAN! I have always struggled running LOP - typically I could get down to about 10 degrees LOP (7.5 GPH at 24 squared), but any less than that and the engine would let me know. Friday I was able to go down to 6.9GPH and the engine was quite happy with me on my 0.7 hour test flight. I went for a 2.4 hour flight yesterday and experienced the same smoothness and ability to run lean.




Thanks for a great product Ross! It's the single best upgrade I've made to my RV.

Default Great Product

Installed mine on M1B tubes. Had to chop them then reweld. All I can say is that this is a great product. Engines runs great after being plagued with induction leaks from poor custom made tubes. Thanks Ross!!
