I did the HO swap a few years ago. I quickly found that I really needed to do the HO governor swap. Unfortunately I was not able to easily find one. Eventually I ran across a medium speed E2AZ-7C063-B truck governor on ebay and put it in. It helped a lot but still not enough.
I finally managed to find the un-find-able... the E8ZZ-7C063-A governor. Bought off E-bay for about $40. I tore down to put it in last weekend. But I put both governors side by side and they are exactly the same. According to the photo below, the recess in the little piston should be a different diameter. They both measured exactly .262 inch.
I also found an old forum post saying the HO governor has a yellow spring. The new one I bought certainly does. But looking closely at the one I've been using, it still has a tiny bit of yellow paint on the spring.
Does anyone have hands-on experience with this? If I got hosed on this part I may try and return it.
