I fired up the 90 today for its first run. Only ran it for about 10min. Followed the instructions, mostly. 15:1 oil, 100 octane non methanol it started right up after a few flips. My question is I tried to unscrew the needles(L, and H) to what was in the directions prior to start but the low speed needle literally falls out at 4.25 turns out and I’ve got the high at 6.5-7.0 turns out. Instructions want 5 out on the L needle. ?? Ran great. I didn’t take it above 1/2 throttle but it even idled ok. I mean of course the occasional miss and both cyl 2&3 were hotter. Also I had it inverted. Figured I’d try it that way until I rotate it. Planning on inverted in the Corsair. Thoughts? Still waiting on rpm tach to arrive and trying to decide on a cylinder temp sensor to go with.
