Saito 60R3 running in with problems

- Cylinder 3 not running. What we have checked: Correct ignition wiring, spark plugs OK, fuel arrives into the cylinder, valves have been checked and re-adjusted, investigation continues... Any ideas are welcome!

Just mount the motor turned 120 degrees with cyliner 3 in top - when break it in. Mount it next with cylinder 2 in top - when break it in. Then you will have all cylinders broken in with correct temperature. It will run better after this break in procedure.
Hey there! Thank you thats exactly what we did, i also posted an update video. Now with normal oil content and engine peaked out it runs OK.
Szép motor Attila! Üdv itthonról :D
engine *almost starts*

Glad to hear you solved your engine problem, this is a great engine. Is that a Saito or Keleo exhaust ring? The Keleos somehow seem to make them sound even better
My friend made it himself:) he used the original exhaust adaptors and made a ring for them
Are you sure that cylinder is actually getting spark bad spark plug, wire? Seen many times brand new spark plugs not any good you need to see it Spark.
I don’t have a gas plane yet what happens if you test the engine in a vertical position.
Is the motor already broke in ? Just asking cause mine was sometimes stumbling on 2 cyl while break in from very rich mix.
ballsdead1 The bottom cylinders tend to run too rich during break-in and if you lean it out the top cylinder might get too hot. The dolution is to somehow run in the engine in different positions. In the air this wont be a problem
What means "might get too hot" ? Did you used a laser thermometer ? It is normal that the cylinders got different temperatures - specially during break in ! How long you broke it in so far - mine took forever ! Maybe you should ask the dealer (you got the motor from) for a solution ? If you are able to tune the carb so that all cyl run, maybe it's a good idea to fly it and see if it gets better (if it's flyable).
Just some ideas ;) Good luck !
Yes it was a laser thermometer. Its not my engine, but my friends. It is run in already and different mixture in the cylinders due location is not a problem because an airplane is never steady, so the engine is always turning in every direction.
Maybe I’m crazy, but I thought the manual wanted break in at full throttle super rich no more that 4000 RPM? The manual also states that it’s ok if a cylinder doesn’t fire during break in?
Chris Burkhalter after the video the engine got 10 full tanks of rich run first with max 4k rpm but at the end a bit leaner at 5k. The top cylinder not running is not good. Without temperature the breakin will not happen
Ahh - good to hear from experience. I’ll have one of these shortly and have been following some of the recommendations to rotate the engine while breaking in.
@@cmburkhalter Rotating was the solution for us, i made a follow up video, since then the engine is running smooth.
HondAttila is correct, if it's not running (firing) then it won't break in, you have to have them all firing to get proper temperature and chamber pressure. The idea is to have full running conditions but very rich and limited RPM, until the wearing surfaces bed in against each other. It's important to spend the time on that stage, keep working on it until you're sure it's running in correctly then follow the rest of the break-in procedure. These are terrific engines and they're well made and durable but only so long as you treat them right. They're expensive and I for one can't afford to wreck one by mistreating it and just get another one, I've got to make them last. I have 2 Saito flat twins (FA-182TD and an older FA-130TD) and they are great, I would really like to be running radials but don't have the budget yet. This sweet engine is a bit of a collector's piece but it's too good not to use them to fly nice models, so take care of it! I always love the sound of radials, no other small engine sounds that good
WOW 👍🤟
On my same engine, I have the exact same problem! On cylinder 3 it only works in some regime!
Sounds great, :-)
Saito + radial = love

From my personal experience with this engine it is a fuel distribution problem In manufacturing. Contact Ray English in Carson city Nevada. He is a machinenist and mechanical engineer and has tons of experience with this engine and other saito engines.
Wich Ring exhaust is that ??
Home made
@@HondAttila nice. Good job
Cool
I would say that lean

By OS-G5 glow plug for gasoline, then the problem is fixt, and you can skip the egnition electronik, and save some wight to 👌
