Here is some test data on my 13B Tailwind.  Marcotte Redrive, ration 25 x 51.
 
1st hour
 
engine rpm 5600 max      prop is Fred Felix 67 x 70, bi-cambered
water temp  190
oil temp       192
fuel press      42
ex temp     1600
MAP           28.5
OAT              76
air speed indicated 163
 
2nd hour
 
engine rpm 5800        At .7 hr into flight the engine was picking up rpm so I throttled back 100 rpm's and tuned the A/F
water temp  185        mixture and the engine picked rpm to 5800 rpm again.  The engine must be breaking in and it was
oil tem         170       running real nice,  VVI was indicating climb of 200 feet per minute.  At this point the Marcotte Redrive
fuel press      42        started to vibrate so I throttled back to 2000rpm on the engine, by this time I could smell 80w and
ex temp     1600        smoke.  I did a 360 turn and I'm flying in the only cloud for 100 miles.  It doesn't give you a fuzzy                                       warm feeling going 190 mph and having a fire at 4000 feet AGL.   My landing was less than stellar
MAP             27        so will have to repair the plane next winter.  I should have been reading between the lines in the
OAT             60         Contact Magazine and replaced the redrive before flight, when it failed the front seal fell out and the
air speed indicated 190         80W followed.
 
Thanks to all you folks for you assistance in getting the engine running real nice.  To bad the redrive was garbage.
 
JohnD....I was really happy I didn't get injured
