ZDZ40 - THE LAST CHANCE ???
ZDZ - the never ending story ...
Okay, this weekend I gave it another try with the zdz.
Here is a short summary:
- I took the motor off the plane and mounted it on a board, no extras, security switch what so ever - plain vanilla setup
- I printed out Gunny11 instructions and went to the field
- After mounting it .... I right away used the setup suggested by Gunny11 - H 1 and 3/8 L 1 and 3/4 settings
- I primed the engine (full throttle, choke on, iginition off) roughly 6 times/flips
- Choke on, throttle idle, ignition on - the beast fired on the first flip
- Choke off, throttle idle (a tick more), ignition on - 2 flips and the beast was running
hmm - and now????
I was ready to throw it away and it performed llike a charme! I still need about 15 flips or so once the engine was hot, however, according to Gunny11's instructions, I probably will be able to get that fixed as well.
The idle was ok for a motor with only 20 os of gas through it - I had it stable at around 2000 rpm with a 18x10 Bambula. Full was okay too - 7650 rpm.
Gunny11 I need one more hint from you: If the engine is running WOT it has a nice solid sound - very clean, however, once in a while a little this sound is interrupted by the sound the engines do if they run a bit below the full throttle (don't know how to describe) and then it goes back to the nice sound. What can that be? Not enough fuel? Large tubing???
Summary:
First of all I am quiet p.o. that nobody else was on the field. They probably won't believe it (if I have trouble the next time?!?!).
Second: I don't care as long as the ZDZ runs and does what it should do - take my nice Giles and Katana up there ...
I guess I will have to find out what I have to eliminate from my setup to find the failing part.
I am still somewhat reluctant but the zdz performed 1A today - really!
