starter issue - a BP starter will start this engine and most any other up to

<p><font size=3 face="Times New Roman"><span style='font-size:12.0pt'>Second -
is there any reason you've decided you need a pump on your AX? I recently
completed my GiantScalePlanes Swallow 90 with the 120AX -- (with the head at
about 8:00)</span></font><font size=1 face=Tahoma><span style='font-size:8.5pt;
font-family:Tahoma'> which is about the same size and config as a Quest and it
doesn't need a pump. Tank is on the firewall; engine tunes fine and draws fuel
fine with stock carb and muffler pressure. </span></font><o:p></o:p></p>
<p><font size=1 face=Tahoma><span style='font-size:8.5pt;font-family:Tahoma'>This
setup gives me all the vertical I could want (duh... a 120 on an 8-1.2 lb
plane- yah...) with no indication at all that there's a fuel feed
condition. </span></font><o:p></o:p></p>
<p><font size=3 face="Times New Roman"><span style='font-size:12.0pt'>Might be
easier to go back to stock setup and just fly? <o:p></o:p></span></font></p>

OS120AX Run/Set-Up Problem</span></i><br>

>HI....I have a new OS120AX that I put in a Quest<br>
>airplane. The engine is mounted inverted. The fuel<br>
>tank is at the airplane CG and I'm using a VP-30 Perry<br>
>regulataing punp. I have the low end needle valve (OS<br>
>calls it the mixture control valve) at it's maximun<br>
>lean position, but it isn't lean enough. I had the<br>
>same problem with an OS50SX and fixed the problem by<br>
>modifying the low end needle valve so that it could be<br>
>adjusted beyound the designed maximum lean position.<br>
>The 120 is a different design and cannot be fixed the<br>
>same way. The basic problem is that the Perry pump is<br>
>putting out too much pressure at the minimum presssure<br>
>setting and this results in too much fuel being<br>
>delivered at idle. If the taper on the main needle<br>
>valve was changed to allow it to engage deeper into<br>
>the mixture control valve at the idle setting, this<br>
>would fix the problem, however, I'm not sure I could<br>
>accurately and precisely change the taper. Any<br>
>suggestions?<br>
><br>
> Also, my starter doesn't have enough torque to turn<br>
>over the 120, so I have been starting it by hand. The<br>
>problem here is that I cannot start it with the engine<br>
>inverted. The fuel just drips out of the carburator<br>
>(onto the ground) and is not sucked into the engine.<br>
>When I turn the airplane up side down it consistently<br>
>starts with the first flip. Obviously I need a higher<br>
>torque starter so that a higher turning rate (RPM)<br>
>will develop the sucking powrer to pull the fuel into<br>
>the engine. Any suggestions on a starter that will do<br>
>the job?<br>
><br>
>Thanks in advance for your help.<br>
