We present 1-2 arcmin spatial resolution CARMA-8 31-GHz observations towards19 unconfirmed Planck cluster candidates, selected to have significant galaxyoverdensities from the WISE early data release and thought to be at z>1 fromthe WISE colors of the putative brightest cluster galaxy (BCG). We find aSunyaev-Zeldovich (SZ) detection in the CARMA-8 data towards 9 candidateclusters, where one detection is considered tentative. For each clustercandidate we present CARMA-8 maps, a study of their radio-source environmentand we assess the reliability of the SZ detection. The CARMA SZ detectionsappear to be SZ-bright, with the mean, primary-beam-corrected peak flux densityof the decrement being -2.9mJy/beam with a standard deviation of 0.8, and aretypically offset from the Planck position by approximately 80 arcsec. Usingarchival imaging data in the vicinity of the CARMA SZ centroids, we presentevidence that one cluster matches Abell 586-a known z~0.2 cluster; fourcandidate clusters are likely to have 0.3<z<0.7; and, for the remaining 4, theredshift information is inconclusive. We also argue that the sensitivity limitsresulting from the cross-correlation between Planck and WISE makes itchallenging to use our selection criterion to identify clusters at z > 1.
