How to open up rocker arm oil passages.

.032 will work, but you will have to make your drill wire shorter, as it will want to bend easier. Use a good air gun with a rubber tip and at least 90 psi to blow out the oil ports.

BTW, what kind of homebuilt was it. Did you finish it? Fly it?
This is good - I have a plan! I'll report back when I get er done. My welding buddy is on the way over to spend some more time building the exhaust from the Clifford headers he welded up to fit, so it will be a few days before I get back to the rockers.

My airplane was a TEAM EROS. A 50 hp, dual carb, dual ignition Mini-Max. I used to build custom hardwood furniture for a living so I figured I could source aircraft grade spruce and build it for nothing. Buying everything that wasn't wood - one part at a time was a lot more expensive than just buying the kit from TEAM. I have a CFI in SEL but didn't have a tailwheel endorsement at the time. Tried three times to get my endorsement in a '41 Taylorcraft that as 300 miles away and came up snake eyes each time. Mechanical issue, WX, CFI had the flue.. I wasn't going to be the test pilot without an endorsement and some emergency procedure currency after spending all my time and money building and not flying... Got to crow hop it on the gravel strip I was hangered at. Barb wire fence on one side and a drainage ditch on the other. At the '08 market crash I had to sell it for pennies on the dollar. If I didn't need what I owned to sleep on, cook with, or drive to three part time jobs, I sold it to survive. I was a little bitter about the whole thing until I met an old acquaintance that had to sell his antique Harley collection to survive. At the end of his sad sack story he had this grin on his face and he said if he didn't have the stuff to sell, he never would have make it. Completely changed my outlook on the '08 market crash!
