Have a DLE55 in a Yak54 which was in storage for over two years. Started and flew last weekend but it would have a very slight hesitation at the low end and during quick transition from low to high. Ran it on a 32:1 synthetic mix from a friend’s gas can while I always used and tuned this for a 40:1 synthetic STIHL HP ultra. It improved after the second flight but the slight hesitation was still there.
- Try it with my own mix which this was originally tuned for, fly and see?
- Also try to tune the low end slightly rich?
- Or is it advisable to rebuild the carburetor with a new rebuilt kit as this was sitting for more than two years? I don’t think the carburetor requires a rebuild as overall the engine performed pretty well the first two flights after a long break.
Will report back on this next time I fly it with my own fuel mix and if needed will tune the low end slight rich.
