Magnet just as it sparks
It stayed perfectly clean.
Not bad for a 13x6 Graupner G-Sonic
Thanks Gary, I just put an hour on it at 40 degrees btdc and it runs great, easy to start, the rpm blew me away, I never expected that. I has about 2 hours on it now. I took a picture of the magnet just as it sparked. This ting does no like to be rich, one click rich of peak and it slows, two clicks rich and it misses and at three clicks it nearly quits. At peak it is super smooth. It has a big, authoritative sound for it's size.
PS, I used a new 4.8 volt CH Ignition unit.

Charley, I use this one glued to .125"ply and then cut out on my band saw with a .125 in blade. https://www.google.com/search?q=Degr...fwdXiqnLclazM:

Okc that old pipe reamer sounds good,some people get picky about prop reamers i think it's up to the user's skill and preference.I made and tig welded some cheap bunnings/kmart stainless bathroom towel rail pipe for the exhaust stacks on the fg57 powered edge.
Jesse do you have your fa182td yet? i'd like to hear your comments re running the 182 in i'll post a pic of mine in the h9 taylorcraft with the cowl off because i think the twin carbys look awesome.Imagine if you will that all the people on this thread are sitting down at a round table in some smoke filled outback mexican cantina late at night playing poker.We're all drunk on scorpion juice/tequila and talking bike histories so i say...i'll see your 1968 royal enfield interceptor and raise you a three speed bsa bantam two stroke
and have you ever owned or ridden the original kawasaki h1a widowmaker,some people say it was the later mach four 750 triple but not so.The 750 was more gentle in it's power delivery even tho it had lot's more.

Rode but never owned The H1 Kaw. They were very popular around here for the straight line riders My buddy was killer on one.
The 182 arrived on Wednesday but my pics have been hi jack fodder it seems(Not green falcoon furds after all)
Hope this one lasts a while before the burial or hi jack folks take it away

Congrats jesse it's a beautiful engine please update with photos,maybe a bench run vid?? here's a pic of mine in situ running a mas 18x6 classic prop.Ran mine in about five years ago and it flys the hanger nine taylorcraft with great authority.

Pssstt dave i'm curious and worried,it's very still and quiet here.Call me paranoid and you may,jesse has a good point.Is there some maniac who is randomly deleting posts and pics willy nilly? and what are we doing about it? are the other thread members right this minute frantically pm ing each other and running some kind of underground sweepstake/raffle so they can bet on who it is?

The engine stayed perfectly clean throughout.
No need to be curious or worried.
New numbers for the FG 11 using a different tach, I sure wish my TNC still worked.
Graupner G-Sonic 13x6====10,410 rpm
Xoar 13x6 ==============9,000 rpm
MA 13x6 three blade======7,500 rpm
MA 12x6 three blade======8,400 rpm
The FG 11 does not like to be rich, not even a little bit. At one click rich of peak it slows about 75 rpm, at two clicks it loads up and nearly quits. At a couple clicks lean it surges and at three click it just quits.

I usually skip all the bench testing and break them in on the plane. I will keep the board up to date.
So far only one photo/ post has gone missing. It was the one with the pornoraphic BSA Rocky Three.
Red BSAs are quite seductive after all.
I’ll risk it all and post again. The pic is about 37 years old. The bike was totally pulled down to the last nut and bolt.The engine was rebuilt and modified, the wheels Re-laced. This was my first time painting with Kandy Kolor lacquer paint. The pin striping was the only thing I farmed out.
1969BSA

Jesse could you do me a favour when you have time? and take a nice close up pic of the screw heights in both carbys and measure the heights or count the threads from the bottom of the holes please,they are different from side to side as they come set from the factory and i've lost my original setting notes.And it's a bit weird looking down the inlet throats and not being able to see the throttle barrel as you do on the singles eh?
I'm not big on endlessly bench running saito's either.The fa182's are very smooth from the get go,the factory settings are very close so you could probably fly the engine from the third tank onwards if you took it easy for a while.My fa182 is still on the original factory bearings,no wiggle in the crankshaft shaft when you rock the prop tips,it must be due to the 3% castor and 15% synthetic oil mix.I threw the priming harness out too.The singles vibrate so much when rich/new i don't do that to airframes they suffer a lot cheers.
ps that rocket three is awesome hav'nt ridden one for 45 yrs now but you never forget them.If we get one in the shop or i see one at a vintage motorcycle show i will take some pics.

Well, I finally did it last Friday. Crashed a plane to kindling. I'm not upset about the plane since it was pretty well beat up, I just missed the loose aileron that caused it to go in. What I am peed about is that I busted the cylinder head on the Saito 72. THe exhaust thread snapped off. 
Now have to find a new one. Was my best engine, never let me down.
I had seen some repair sticks for Aluminum, it worked like solder but the bond was stronger than the metal, and all it took was a torch. If I could find that, I could fix the thread part that broke off.

Ouch
The ever vulnerable exhaust threads That aluminum repair stuff may rove a bit dodgey iti is little more than a zinc alloy It is not real strong and requres all oil cleared out of the area And then you will have to size the hole and somehow retap the threads.
If Clarence Lee is still offering the service, he does an outstandig repair for about $25

Hey there Old Fart
Glad to see the Rocket pic has managed to hold up this time The rides on that bike are very memorable
My buddy had a 1968! XLCH Harley Sportster He had thought the 750 Rocket no match for 900cc of Harley muscle Of course he was wrong
I'm not certain which measurements you need Here are a few:
Idle air screws from carb body to bottom face of screw
left hand: 5.0 mm right hand: 5.6 mm
High speed needle from bottom of rim to carb body:
left:!3,56mm right: 3.1mm
I can count turns to close if you like
Not certain if this helps as they may use a flowmetet to set the needles at the factory Let me know

Dave here's a pic of your ideal retro lawnmower and a 1969 yamaha xs650 in your colours.The next two pics show what happens when the cafe racing crew get hold of one.Turned up at the workshop today.
ps bruce(acdc) was talking about heating a hard chromed and ally saito cyclinder to repair the exhaust thread,is that wise and does clarence lee do it?

AB screw in left front and right rear.
When all things are normal the AB screws should start at halfway across the hole and then end up very near there at the final setting. They don't have enough authority to make much difference anyway. The right AB screw on my 1.00 faces the rear so I lift the carb off, set it halfway across the hole and leave it.

OF,
Not sure which carb you are using; Looks like the new can is quite different from the older
The screws in the photo are as they came oit of the box You can see the left is nearly closed and the right is slightly under half open You can get a good idea from the differnce in the measuremenrts given
What Dave said makes sense

Old bearings
New Boca Bearings
Thanks Gary and Pete, I think I discovered why the 1.50 didn't have any oil coming out the rear vent, out of curiosity I popped the prop driver and discovered that the factory seals/shields or whatever, were spinning with the inner race. New Boca Bearings are installed, the engine is not fully re-assembled yet. I'll report in a day or two.
