naa, it's because he likes me and wants me to be happy

OF, I will be happy to post photos,

BTW, my P-40 came with a rather small Fuel Tank, 355cc (12oz), what size should I use for the 125, I was thinking 473cc (16oz),, but I read on a site to use 532oz (18oz),, what you say guys ????

Jim the 12oz tank is ok if you fly for ten minutes you won't be at full throttle most of the time and can afford to go round a couple of times if you miss the approach.

Acdc commiserations on the bipe.I had the opposite flying my h9 taylorcraft where the throttle stuck full open while doing touch and go's.The golden rod clip got stuck in the fins on the right hand cylinder even tho i'd cycled it a hundred times with the cowl off,had an 18oz tank in it and had a 20 minute flight at full throttle before the engine karked it,safe landing.

popo if it looks like a duck and sounds like a duck..remember the cheech and chong comedy sketch where (fifi the dog) the long sharp nailed large poodle is getting her nails clipped in the dog parlour?

Jim, a Saito with optimal needle settings will consume 1 oz of fuel per minute per cubic inch of displacement. (at full throttle) Actually that goes for any four stroke, the larger engines are slightly better than the smaller ones. Something about the larger ones turning a little slower and internal friction being less of a factor. The LS needle is especially critical for economy.

Good morning Barry, Just come right out and say it, you don't like my 50 minute Saito break in even though it has worked about 36 times. And I'll never agree that it takes 5 gallons to break one in. But we love each other anyway. Having said that, this 1.00 that I rebuilt is still a little draggy after one hour of running. I'll put another hour on it today. I'll report. Basically all that remains of the original is the crankshaft and valve train, back plate and rocker covers. And the carb too, the intake pipe was bent and is new.

I apologize for hitting the Edit button instead of the "quote" button

It almost qualifies as a new engine!

Yessir, and I treated it that way, my plan for today got all shot to pieces, I'm trying to remove right exhaust manifold from my son's 2001 Ford Explorer with the 4.0 litre SOHC engine. One stud came out, three nuts came off and two studs twisted off. Oh joy.

The rebuilt 1.00 does run nice and smooth though.

yeeaa, me too, it was a family thing, so I didn't get to the bank to transfer the money so I couldn't order my engine, I highly dislike calling on the phone to transfer money at the bank

soon to own a Saito Jim

Jim that might not be a good idea.If you bury the p40 and saito 125 people here might start thinking groundhog day and an unkind mod could change your moniker pard..just sayin

Dave don't stress the run in thing different strokes different folks,remember the old saying about asking two pilots for an opinion and getting three different answers.It's all good fun mate.On your saito 100 do you mean the intake pipe was bent out of shape and no longer fitted? i drilled a small extra 220 into the ground and it damaged the inlet tube and bent the crank.The inlet tube was struck on the firewall side and had a sharp crease that reduced dia by about a third.Rebuilt the 82 engine and put a good inlet tube from one my others,it pulled the same rpm so i was happy.While the cowl was off i swapped the good tube for the damaged on and it gave the same revs,no difference,does that cheer you up!

ps jim don't throttle the 125 up too quick on a taildragger they tend to nose over on the takeoff run to the point where i've backed the throttle off and the aeroplane has jumped off the ground...just helping you get up there successfully so you can bury it from a greater height pard

Good Morning Pete, yes sir, when the front two cylinder base bolts pulled out of the crankcase, the cylinder moved up and back bending the intake tube, the rod and you can see the cylinder busted out at the bottom. The piston may have been useable but didn't cost that much to replace. The crank is straight. I have no real need for two 1.00's but no one would buy a, "new assembled" engine.

funny you say that, because 2 nights ago on YT I saw a .60 size P-40 do that

I got a chance to run the rebuilt 1.00 today for about 1 hour and 15 minutes burning about 26 oz of fuel, it is now freer and smoother than with the previous 1 hour on it.

Saito 1.00 built from parts, many new and a few old.
Prop====Xoar 15x6
Fuel Wildcat 10% 2&4 with 18% full synthetic.
Plug====OS-f
Exhaust===stock
Max RPM===9,075 absolute peak with slight Pre-ignition
Best rpm===9,000 super smooth and quiet

Pictures taken at random 7,100 rpm, some smoke.
Idle 2,000 probably not optimum yet.
No leaks anywhere.
I think I can safely say I did good.

Nice and an update on my Saito 200ti. It is running good I have about 1.5 gallons through it and took it up for a flight on a P-51 150 with a 16x8 prop. Needs a bigger prop for that plane so will change to a 16x10 or 17x8.

Hobbsy

My Feedback: (102)

Thanks, I guess a 16x8 would be a little light, how would an 18x8 look on the Mustang?

See Dave, that's why you are like my wife. You don't hear what I've been saying for years now. Seriously, I've always said that your break in routine is almost to mine, and I normally tell members to use the Hobbsy method. Really, the only differences I think between your way and mine are minor- I'm not strict on the times, so it may be a 10 minute tank or 8 minute tank, or 5000 rpm instead of 6000 based on how the engine is running. What I'm saying is that I'm not too strict. I do keep "break in" to not less than the 40 minutes Saito recommends. I may even put a little more time on it just for fun. The other thing is that I think I probably run mine harder on the bench but I'm just guessing from how you describe it. I give Saitos a lot of WOT time- usually small blips at first, then maybe 15 seconds, then up to a minute, etc. The last tank is mostly wide open throttle with some breaks to idle a minute or two.

As for the engine being honest to goodness broken in I've never heard of 5 gallons except 'maybe' the old Tower 75 being more like 4 gallons. You and I are probably chasing our tails meaning the same thing. The first time I say I'm breaking in a Saito is to run it 40 minutes on the bench about 95% exactly like you do. Then, it's ready to put on a plane and go flying knowing it will still not have the best fuel economy yet, it may be a bit rough running compared to what you expect from Saitos, and it will for sure need the low speed needle tweaked often. Parts begin to mate better, high spots rub down to become smooth spots, and all the parts work together smoothly. That's 'breaking in' too. Every Saito is different. My 82a probably won't need a gallon to be 100% 'broken in' with max fuel economy, power, and needle stability. My 56 was pretty easy and fast too. The 72 took more than a gallon before you could say it had reached max fuel economy and the needles stayed set for the season. The early model 125 took gallon after gallon and I had to set the needles every time I went to the field. But, when I got the needles dead solid perfect it ran like the best Saito you ever saw.

The 10 minute runs are not strict in my case either, I come close, today I weeded the garden while running the rebuilt 1.00, but I had done the 50 minute thing a few weeks ago. The 1.00 was a little draggy after the 50 minutes. It's not draggy now and has fierce, no leak off compression. I ran a lot of todays run at 6,000 and above, it was 90+ here today so I gave it a 5,000 rpm break every few minutes.

Hell no man used to know a woman like you once,she'd been under everything except the titanic.First you arghu ing tween a 115 and a 125 then you want a 100 from dave for your soon to be crashed p40.It's enough to turn a sober man onto the wrong track cuz
