Thanks to all for the ideas re door gas struts. Should be sorted now.

Next problem. The sockets on the plenum chamber for my 912S, where they go into the rubber hoses to connect to the carbs, have collapsed somewhat. I guess it is the combination of the heat from the engine softening the glass and it being under compression from the hose clips.

I was considering cutting them off and reduxing in a couple of short pieces of 2in. aluminium tube as replacements.

Any one else had this problem and how solved?

Hi Richard,

The carb socket area should not see particularly high temperatures.
The clamps are probably too tight. Of course, if the plenum pops
out in flight, the engine will run very rough.

Do you support the plenum on the firewall side of the box? I have a strap
of aluminum coming up to a nut plate on the back wall of the plenum.
It seems to help support the intake system combined with only moderate
tightening of the band clamps

I simply re-enforced the plastic by inserting aluminum tubes C I think the diameter should be 1 7/8 th inch.
No need for redux C just some heat to get them in.

Richard,

I replaced the plenum's completely using 1.75" OD thin wall aluminum
tube from ACS. I cut the old ones off, inserted the tubing and glassed
them in with 2 layers of bid. Tighten them as much as you want, now.
They "ain't goin' nowhere"!

Hi Richard

Funnily enough I have found a similar thing had started and was thinking about how to fix! Let me know what you decide.

Cheers

Rick

Richard,
What you suppose to do is exactly what I did from the beginning. Make the aluminium tube rough outside for good glueing. I also took another rubber tube of better quality from a racing car shop.

Hi Richard,

I had the same problem. I fixed it with aluminium tubes glassed into place.
