<p class="MsoNormal" style="margin-bottom: 12pt;"><span style="font-size: 10pt; font-family: "Verdana","sans-serif";">I have been running my 160DZ with a 4 blade
prop but needed to switch to a 2 bladed prop since the 4 blade is not longer
with this world. It was VERY hot and humid today in Michigan, and the
18.1X10 2 blade seemed to be loading the 160DZ down a tad. It was turing
about 7700 the other night when I tested the engine/prop combo. After my
first flight today, the engine would audibly sag and then die suddenly when
running at full power for more than 10 to 15 seconds. So, my questions
are:<br>
<br>
What props are other people running on their 160DZ's?<br>
What RPM are you turning?<br>
How far out are you on the main needle?<br>
Fuel?<br>
Of course, any suggestions about anything to check would be appreciated.<br>
<br>
FYI, for me, I am running at 2.25 turns out, 7700 RPM and using 30%DZ blend
PowerMaster. Turning in the needle any further will cause the engine to
sag audibly.<br>
<br>
My second YS topic has to do with the small bearing that supports the
cam. I tried to heat the case slightly and pop it out with a light tap on
the case. I tried to pull it out with a modified tool with a small lip on
it, but it is not budging. Looks like what I really need would be a
reversed small gear puller, but I doubt the local hardware stores carry
that. So, any suggestions about how to get that little bearing out?<br>
<br>
Thanks all<br>
