Yup,
NX-26. I think that was my second one. Well the first one was my first nitro engine ever so lets call that the mulligan. The second one was no better and spit fuel and leaked air and acted all screwy. Was pretty fast once in awhile but I threw in the towel with that engine entirely. CEN has been awesome about sending out new needles and they even have a cheap replacement program that allows for a swap of the busted NX-26 for their tried and true SH. 28 at a super reasonable price.
