However, the Bing carbs have vacuum operated sliders. The dome at the top of the carb is a big rubber diaphram. It actually pulls the slider up when airflow thru the carb creates a vacuum. i.e. there is no internal mechanical linkage to the slider. By the way guys, I haven't looked at them in a while, but I do have the Bing manuals on the carbs. I don't remember the exact number, but it does call for some rediculously low number of hours to inspect and rebuild the carbs. Something like 50 hours. I'm guessing that it's because of that rubber diaphram.

He said take a small drill bit (I used 1/16") and put the shank under the slide to make sure they are mechanically synced. I did that when I hooked up the cables and the engine w/o prop was perfect so I never did the vacuum sync. I'd like to do that now. Do you guys want to split one? I can get one for cost and mail it to the next guy after I use it. Just a thought, if not I'll just borrow his.

For the last gee, five years now I have used the eyeball method. When I connected this fancy differential pressure transducer I got a vacuum difference between the carbs of 2" of Mercury ...Thats about 1 psi, not a huge amount abut that was after considerably fussing with it. With the meter I was able to dial that down to less than 0.1"Hg difference with ease. It did take away some of the lumpiness in the engine...But I still got a prop/belt vibration. Gotta get the prop balanced I think...:) Frank -----Original Message----- From: owner-stratus-list-server@matronics.com [mailto:owner-stratus-list-server@matronics.com] On Behalf Of Bill Morelli Subject: RE: Stratus-List: carb sync --> Stratus-List message posted by: "Bill Morelli" Frank, Seems to me the eyeball method would be fine assuming that both sides of the engine are pulling the same vacuum. If they are not for whatever reason, then having the throttles mechanically matched would be incorrect and the pneumatic method would be needed to get the carbs moving the same amount of fuel / air. Does that make any sense?

I'll try your method too Kelly. i'd like to try different tensions to see how it affects noise. I actually "saw" the infamous rum-rum noise (as described years ago on airsoob) on my plane. I saw the prop flexing forward and back (coning out) and kindof wobbling in a 1 second or so interval. the sound matched the prop wobble. not sure how 2-blade vs 3-blade, cowling shape, belt tension, etc add up together. This is the harmonic vibration I talked about in my previous posts. The engine and prop rotates at different speeds and hence any balance issues would show up as what you call "rum-rum". I have noted that my props would flutter (flex back and forth) at certain rpms where the harmonic vibration would be greatest. My solution to that problem was to have my props balances and *voila!* the rum-rum went away and I celebrated with a shot of rum! So, if you have rum-rum, you need to balance the props after properly setting up your belt tension and making sure all three blades are pitched equally.

Take the 3/8ths balance tube that connects the two inlet manifolds together. Either cut the tube or pull it off and you have a 3/8ths hose connection right there. The idle mixture is the one facing UP on the downstream side of the carb next to the float bowl...Underneath the carb. I would set the idle vacuum first (you can set the idle vacuum by adjusting the throttle stops, they act on the throttle arms) and then use a colourtune to set the mixture. I never got my idle mixture quite right on the left bank, but it doesn't really matter because the effect is miniscule at cruise. Then set your carb balance say at 2000 rpm...Once you get it right it should stay the same throughout the rev range.

I did find out that when the cables are not tightened down, arcing within the contacts of the starter can permanently increase resistance at the solenoid. I was advised that the 7.5 amp fuse was way too small for reliable service life of the Stratus starter solenoid. Also spoke with Mykal and the prospect for replacing the starter wouldn't have worked either because the motor size has increased to the extent that complicates the carburator arms and cross-tube we know today. I did order an unpianted right upper motor mount for the eventuality........ Thanks for the advice and comments.

I stripped my old one before my repair by sandblasting it, took about 30 minutes as that stuff is tuff. FWIW Mykal sent me the following note: "It was zeniths Idea to go with the longer mount on the right side so thier atrtachment frame was easier to make most leave that side short and the attachment frame is ofset so we do have more load on that mount. thanks for the update on your project. looks good . " Also nice to hear your starter problem is solved.

Why the heck didn't he have a stronger mount made?? Mine failed two years ago, I notified him and he sent me the same exact mount and he is still sending out the inadequate mount!! I guess he doesn't realize or doesn't care that one of those mounts could have had a catastrophic failure leading to engine stoppage. I guess I've vented enough!!
