Dave.

The last scale day i had a dead stick with my 3W85 for the first time in its life it had overheated.
I managed a good landing.
As luck would have it i was in the correct place at the correct time it does not often happen but it was a perfect landing.
A month before i had had 4 flights with no trouble so i was mystified, i seem to remember that it was running rich and i must have leaned out the high speed needle at some time but i cannot remember doing it.
In the back garden with the cowl off it was going over 130 degrees and dying much to hot if you run an engine at that temperature you will kill the piston ring by taking the temper out of it and it will lose its spring and you will lose the compression.
I found that i had to open the high speed needle by 1/2 turn now that is a massive amount usually you move the needles in 1/8 turns as they are much more sensitive then glow engines, how it got so wrong i don't know it may have been me mucking about or it may have been vibration.
I also retarded the ignition to 25 degrees before T.D.C. that gives the bang more time to clear before the next bang and thus more time to cool.
I also ran it on 30 to 1 oil instead of the 40 to 1
It was running on synthetic of course no minerals please you will gum up the engine.
I also ran it on 91 unleaded instead of the 98 i was running on.
Now it is running about 110 C. still a bit high 100 C. would be better. so of to the field to get it in the air.
Last Friday i had dumb thumbs and for some reason best known to a part of my brain i cannot get to.
On take off it swung to the right and into the long grass and damaged the plastic section of the Robart retract again that's the second time i have done that, its a $10 part so no problem replacing it but this time i have tried repairing it with JB.Weld and couple of screws i will let you know if it holds.
In the first shot you can see i have replaced the top section that had broken off and filled in the webs with JB weld in the second shot you can see the 2 screws i drilled through the broken off section into the JB weld before it went solid that should give more grip in holding the broken top section in place.It feels very solid but i don't know what type of pressures this part comes under during a hard landing, i do know that it will break if you abuse it like i have on 2 occasions but with a 35 Pound Warbird they do not stop like the light aircraft they keep going and if the long grass gets in the way i would rather it break here then rip the retract out so its a weak spot but it has to break somewhere.
This part is the end plate of the retract unit. The plastic part on the right in the shot is an undamaged end section that i have spare but it has a different opening degree 75% i have in the P47 90 degree so i could not use it.
In the shot the end plate on the right was used in my now departed TA152 and i had to sand of the bottom to fit it in the wing.

Well the P47 had its seventh flight last Friday, i seem to have solved the overheating problems but its running so rich now it will need some leaning out for the next flight.
PS. My retract repair worked ok!!
