I had a problem with the engine quitting on takeoff that had to be
addressed. I pulled the entire fuel system out, and started anew.
Made sure the tank was as close to the firewall as possible, and high
enough that at about half a tank, the fuel was even with the fuel
nipple. There was an impingement of the cowling near the spinner that
looked as if it would impede airflow, so I cut that away. Used the
largest fuel tubing I could. So, after improving the fuel setup,
(really just doing what I knew was right in the first place) I've not
needed pumps or any other razzamatazz for perfect running. 3 different
engines, not a deadstick among them since I re-did my work. If it
ain't broke..............<br>

[SPAM] Re: Moki 180</div>

Ron:<br>
I've been quite happy with mine; they have always started very easily
and run well. I've heard all these stories about pumping/regulating
them etc. but I honestly don't know why one would need to do so, other
than a defective setup in the first place. I just run muffler pressure.<br>
Now, fuel:<br>
I experimented with some 15% that I run in my Y.S.engines. As the Moki
neared full throttle, I could plainly hear it rattling. (with my
hearing, that in itself is a minor miracle.) So, I drained the 15% and
put in some 5% that I happened to have. Ran well, but after it heated
up, I could detect some detonation. So, I drained out the 5% and put
in some FAI that I had been using. Not only did the detonation cease,
but I picked up some 400 rpm. I was curious, so I called Gerrard,
(importer, at that time.) Jim said that I wasn't dreaming; the engine
was designed for FAI fuel, and that they absolutely would recommend no
more than 5% fuel, and that to be used only in the winter to help
starting. I don't remember numbers, but I do remember that it will
idle for 5 minutes at 1800 rpm, and then immediately accelerate to full
throttle when asked. That's Jim Gerrard's criterion. I'm not sure my
Y.S. engines will do that. Since I've gotten so heavily into pattern,
I have done very little with anything else. So, the information is
probably a year old. The Moki's are in (Individually, of
course<G>) a Midwest Extra 300 which weighs 14 lb. 4 ozs. and I
use a Mesjlik 20-10 prop. This is the only airplane I have ever owned
that will truly go out of sight straight up, (John Ferrell was a
witness on this!) and will do a true, round knife-edge loop. And, with
the recommended Bisson muffler, I get quite a few comments about how
quiet the airplane is. It sounds mellow, but I've never Db'd it. Fun
to own and fly? You bet!<span class="moz-smiley-s1"><span> :-) </span></span><br>

Piped, propped and mounted correctly, it could be made fairly quiet. It
was nice to just fuel it, prime it, one flip start it, and have it last
several seasons without any hint of a problem. No bearings, no rods, no
rings, or anything else for that matter. <br>

I have virtually no experience with MOKI engines, other than to sell
fuel to owners and listen to complaints from the ones who aren't
convinced that MOKIs want/need low % nitro fuel to operate properly.
Does anyone care to comment which fuel works best in their MOKI? <br>
