well my wife is getting better and better. her voice is getting stronger but she coughs if she breaths in too much air.

we were both tested yesterday, so it will be 3 to 10 day before we get the results back. I will be sure to let you guys know what the tests tell us.

but I tell you, if it is corona, in our cases it was really not that bad (thank God), as for me it was just a slightly dry broncular tube for 3 days. if it is corona in our cases maybe we just didn't breath much of it in. I don't know how it spreads inside the body.

be safe my Saito Freak Friends !!

"SFF" LOL

Swapped out the 100 carb for the original 82 carb and all is good again!

Once the ring broke in fully the engine didn't need or want all the extra fuel supplied by the 100 carb I guess.

With 15% nitro this engine has a very wide window of adjustment on the hsn. It's probably borderline over compressed on 15%. Even though I can't hear any predetonation or see any deformation of the plug element it sure is acting that way. I may go ahead and shim the cylinder up .005" as I mentioned last year.

hey Lonnie, remember, you told us you had to seal the 82's Intake Manifold to the 100's carb. maybe it is leaking, or maybe you need to use the 100's intake manifold. you never know till you try/check,

I would really like to see you try the 100's Intake with the 100's carb LOL

Default Gas 4 stroke noise levels

Can anyone advise where I can get comparative information about engine noise levels. I'm seriously considering purchase of a Saito FG19R3 19cc radial with an exhaust ring but I won't buy itr unless I can be reasonably sure I can get it under the UK BMFA 82dbA at 7 metres rule.
Many thanks for any links or guidance.
Regards Bob.

I can't help you with that, but you can start by watching videos on YouTube

Default Saito 65

Lonnie,
Any interest in a Saito 125? The one in the video, including the custom muffler.

I would be amazed if any 4 stroke failed the noise level test.

any one need a very nice 35cc gasser 2st, I sold my GeeBee so I am going to sell my MVVS 35cc (210), I have $540 invested in it with the Inverted muffler and metal engine mount. I would like to trade it for a Saito 182 Twin, I will throw in some money too if the Saito has low time on it.

my engine was broken in on the bench for 1.3 gallons, and it has a total of 2.2 gallons run threw it, it will turn a Zinger 20x8 peaked at 7600+ and a 3W 20x8 peaked at 7400+. she's a monster for a 35/210.

I would like to put the Saito in my son's 74" span Extra that I had that "gone with the wind" Magnum 180Fr in.

if any one is interested let me know, otherwise I will sell it out right.
hold on, I will take photos.

Jim

here are the photos,
you can see some scratches on the head by the bolts, after braking it in the oil I use (that well known stuff most every one has used at one time) left a build up of carbon on the piston top, so I removed the head and cleaned off the top of the piston. after that I used BellRay Hr1.

the piston is still coated with Graphite, I have the original box and papers and a MVVS accessoriy flyer.

edit; the choke can be set to automatically open by the use of the throttle. it works very-very well, you set the choke closed with the choke's linkage, you flip to prime, hiss-hiss, then push open the chokes butterfly 1/4 or 1/3 open with a screwdriver, flip the prop, then once it start's you can move the throttle stick and the choke's butterfly will snap fully open, it works great.

I love this engine, but I am sticking with the smaller glow planes

Jim

If you recall I found a thicker oring to fit the 82 intake to the 100 carb. I liked to never got the intake back out of the carb yesterday. No leaking for darn sure. The 100 carb is just too much carb for the 82, even with the compression mod and upgraded muffler.

Hmmm

I did notice a similar thing with the 80 carb on the 65.

maybe more pitch or longer prop would help the engine to burn more fuel.

My thinking is that with the a larger carb you're still limited by the intake tube and intake port diameter. Those two things need to match the carb diameter, (increase) or you're going to have reduced air flow velocity through the carb and erratic mixture control. That's my brain's thinking with only 1/3rd cup of coffee.

My thoughts too Dave, erratic on idle and peak and fat in the midrange with the 100 carb is what I experienced. Brand new carb and orings too. It just didn't handle correctly.

To be honest neither one of my 82's are what I'd call user friendly engines and neither makes rated hp. The modded one is very close now but is still short of 1.5.

On the bench every other saito I have run makes at least rated hp and handles fine. I'm convinced that the 82 is just the pig of the saito line.

I would agree.

I sort of learned that lesson from an Enya .46 MKII, when turning a 12 x 6 Graupner Grey it would load up in the mid range because you had to run it about a half turn richer at full throttle. Put an 11 x 6 on it and lean it about a half turn and the mid range was clean and crisp.

I have a friend fellow flyer he was saying the same thing.
so I built two hogs and put the 72 in one and the 82 to in the other. Told him that his plane had the 72 and mine had the 82 but that was backwards.
we flew and he say see the 72 was so much better then the 82. The look on his face when I told him that he had the 82 was priceless. The .82 is a good engine, have found that a 14-6 works great and pulls as hard as the 91 if not better.

Yep, excessive prop loading will definitely cause an overly rich mid range condition. Not just just because of more fuel requirement at peak but moreso the requirement at idle. At least that's what I've found.

BTW, a 14x6 is not too much prop for an 82, at least it shouldn't be.

Crunchy, either you had an exceptional 82 or a less than optimal 91. My 82 struggles to peak an apc 14x6 sport at 9500 where my 91 peaks the same prop over 10100 easily. No comparison between those two imo.

My 72 peaks an apc 13x6 sport at 10100, a very strong runner as well.

Nope, my two 82's are pigs, that's my story and I'm sticking to it.......
