I just ordered some OS A3 plugs on tower and a TT R1. I also turned the needles a bit richer for the next start. We will see how it goes from here.
Do you guys think I could have damaged the new engine with these issues? I had a HUGE puddle of oil under the plane when I was running it in on the ground.
METHINKS you have a bad pressure connection or a muffler problem with the pressure outlet.
Not too long ago I had a similiar problem. The engine quit on final. (Sp. Tigre 75 a good engine) I filled it up, noticed a lot of fuel coming out, Oh well guess I was pumpimg too fast, and started up again. I use the Tetra Bubbless tank, and when it overflows it does just that! HA! Started up and all seemed OK but thought I would check the idle. Well it DID NOT. Long story to short, the overflow tube - which, with these bladder tanks has to be capped after fueling - had a long split in it, above the outlet inside the cowl. Therefore the muffler pressure was simply pushing all the fuel out the overflow and there was no real draw for the engine when the throttle was retarded kinda like the pilot at that point.
Now all these fuel lines of today are really garbage. If you find it in some auto parts store, the 1/8 black neophrene (Sp ?) rubber is excellent for both Gas and Glow fuel.
Kind of hard to find now days. The old dark pink line was good but the blue stuff AIN"T! I am not fond of the fancy color stuff the car guys use. The black stuff does have a problem when used and stored on a model for a long time - like MONTHS - but it is overall the best-of-all. [8D]
