Know Im lost guys,

I had this big boy running infront of my house, with the back fireing issues, open the low end a little over a 1/2 turn and all seem ok, I let it sit at 2000rpm for a min then rev to max with no issues and transhishions seemed great. Put the cowl back on, gave it 5 min to cool down, re starte and run it all over the rpm range with no issue.

So I pack up the P47 for its maden flight today, and got to the feild with my new baby a nice looking and what a disapointment.

It started with no issues, gave it a full 2 min a little above idel around 3rpm to warm up, but while trying to run up to wot, it would stumble up top, run a ruff with little back firing surging sounds would not hit full wot.

Weard as it was fine yesterday, even thow today was a little hotter and muggy,

This sucked as I did not put a door for the needles as it would be on the very top of my cowl.

added some fuel on the top end and it still ran accted weard, I open the top end over a 1/2 turn with no good, then leaned it out over 1/2 turn from yesterday with no diffrance.

I tried to add some fuel on the low end as no diff, but after about 3min of this chaseing my tail, my throttle servo fried Im glad it was on the ground....

The guy I got it from said it was running it great.. but now I wonder.
