    Subject: RE: Starter sequence M14
    Thanks Mark=2C Unfortunately getting Vlad or Dennis to Sydney is a bit beyond my budget. I think our next move will be to rig the Scuba air bottle directly to the s pider valve and make small adjustments and port air directly into the spide r at each correction. That at least will save reassembly of all components as we try and turn the engine over=2C and eliminate in all cases any potent ial problems upstream.

    Subject: Oshkosh housing
    Red Stars, I have a hotel for Airventure this year, right in Oshkosh. I reserved it a very long time ago and as it stands I won't be using the la st two nights as I have to bug out back to Los Angeles on July 29. If anyone needs a hotel room July 29-31 (respecting normal hotel checkin/ou t times which I believe are 4:00pm and noon, although as a Platinum member I can arrange for a late check-out at 2:00pm) please contact me at this ema il address, elizabethrizzosaysit@yahoo.com, off-list. The reserved room is a non-smoking, two double beds with a cont. breakfast. The hotel website says there is a free shuttle running both to Wittman fie ld and ATW. The room rate is $220.00/night including tax, which is how we'd have to do it as I cannot make any changes on the room. I want to see if any of my friends could use it first before I release the room back to the hotel where- they have a waiting list and will charge $3 25.00/night (in fact, they'd love that.) Regardless, fly safe everyone and I will see you there. Elizabeth Rizzo-- -

    Subject: Re: Yak-18T Spinner
    From: cjpilot710@aol.com
    Geeees its been so long, its hard to explain. I replaced 6 bolts with 6 7/16" bolts and fiber lock nuts. As it stand right now, I unscrew the sc rews around the base of the spinner. I than remove the 8 screws that hold the 2 cross-over pieces that are directly behind the blades. Lastly I re move the 6 -7/16" nut bolts that hold two back plate hafts to the prop fla nge. If at this point I wish to remove the whole prop, I just have remove the prop lug nuts and the rest of the spinner plate is behind that.

    Subject: RE: Starter sequence M14
    Mark No worries. Thank you for your efforts =2C and we will perservere with this thing. Nothing cannot be fixed=2C eventually. Your information is indeed d ifferent to what we had been told=2C so we will concentrate on around 12 de grees. Cheers Bill From: yakplt@yahoo.com Subject: RE: Yak-List: RE: Starter sequence M14 Again Bill=2C sorry for assuming you were in the United States. Personally =2C I have to tell you that I enjoyed Australia more than any place I have ever been in my life=2C and that includes a whole lot of places. I was up in Nowra and made friends with a lot of wonderful folks=2C so the last thin g I want to do is be a wise-ass to a person who lives in a place I'd like t o come back and visit! The air distributor is set very much like when timing the mags. You want t o set the engine to 12 degrees after top dead center referencing the master cylinder=2C which is of course cylinder number 4. Again=2C set the engine to 12 degrees AFTER top dead center on cylinder number four! Now adjust the the air distributor so that the slide valve will open the su pply of air to the number four cylinder by 1 mm. That's the best I can do to help you. I hope it is enough.

I think our next move will be to rig the Scuba air bottle directly to the s pider valve and make small adjustments and port air directly into the spide r at each correction. That at least will save reassembly of all components as we try and turn the engine over=2C and eliminate in all cases any potent ial problems upstream.

    Subject: Yak-18T Spinner
    CopyThanks. Doc From: owner-yak-list-server@matronics.com [mailto:owner-yak-list-server@matronics.com] On Behalf Of cjpilot710@aol.com Sent: Saturday, July 10, 2010 5:23 PM Subject: Re: Yak-List: Yak-18T Spinner Geeees its been so long, its hard to explain. I replaced 6 bolts with 6 7/16" bolts and fiber lock nuts. As it stand right now, I unscrew the screws around the base of the spinner. I than remove the 8 screws that hold the 2 cross-over pieces that are directly behind the blades. Lastly I remove the 6 -7/16" nut bolts that hold two back plate hafts to the prop flange. If at this point I wish to remove the whole prop, I just have remove the prop lug nuts and the rest of the spinner plate is behind that.

So much character and the impression of power! Hmmmm Hmmmm Hmmmm! I modified mine a little so that I could get it off easier (easy 10 minutes). But I do not think these things are worth $4,000! There is just not that much complexity in it. It could even be simplified somewhat. For that kind of money - I'd most likely go "ugly". Jim "Pappy" Goolsby -----Original Message----- From: A.
