OK
The reason I aked is I have one that I picked up that did not have a ignition and converted it to RCxel and installed new carb, runs ok on bench but have not put it in the air yet.

Just for comparision, here is what I'm trying to replace. Note that I just measured it on my plane, and it's exactly 2.25".

Before you give up on the engine check a couple things, Check the pulse hole and make sure they are lined up good and there is a thin metal peace between the carb and engine, make sure it is not leaking air from there, Was told by a person today who knows engine inside and out that the engine is a good engine with some of the bugs worked out.

I'll take a look at the things you've given me in the mean time.

OK, I'll bite. Here's some clues - I was never able to get it to transition well, despite many tuning attempts. It ran like that for a while, then the ignition died and was replaced by RCS (I sent the whole engine in for that). It came back running the same way. About two years ago, it suddenly stopped idling properly, and remains that way despite repeted adjustments. Any ideas based on this from your friend?

I love my RCS140 I would recomend it for the pattern ship with the rear exhaust and a tuned pipe, should bolt right in a pattern ship. mine is side exhaust in a 120 Pitts s2b from Cermark on an 18x6 Xoar unlimited vertical great torque rolls. pricey but cant be beat.(also my first gas engine) what ever you buy make sure it has the power you want,if you dont you wont be happy with any of the choices you have out there.

Haven't replied since I didn't want to hijack the thread into a "how to fix your RCS 140" one, but since you replied... I looked carefully at the options, and it seems to boil down to the EVO as the only engine in the power class that will not require further cowl modification. I eliminated the First Place 1.3 because an owner pointed out just how much less power it has (about half).
I followed Milton's advice and decided to take one more stab at the RCS. I pulled the carb, checked the lineup of the pulse holes all the way through (all looked OK), checked the shim which seemed to be reasonably straight, and then put a coating of Hylomar on both sides of all three gaskets, and reassembled it. Spent another half hour messing with the needles, and while I could get a reasonable transition in both directions, I still can't get it to idle below about 2600 reliably. I'm going to try to fly it this weekend and see how it goes, before I make a final decision.
