I can turn a 25p 25M and Tempest Plus with a Ox66 200 5800-6000 on a ZX202 which is a tad longer. Make sure your PTP is at 3.5" annd run it to see how it does. I went as high as 2.75" and settled at 3.25". It could be that you need a little more cup to get fully on pad or something else.
What kind of shape is the prop in? Has it ever been worked? Steve's Props is good with Skeeters. You could need the prop refreshed with a B&B if it is clean and not worked recently or repaired if its a little banged up.
