yee-up, we made a trade

OF, I thought that Emu Export stuff was for joint pain ?? just rub it on, pain goes away ??

Sacre bleu!! a french way of saying holy God...i never rub emu export on any of my joints and especially not on a nice cuban cigar,although i have rested a cigarette on the workshop bench while priming a saito without noticing that it sucked up a bit of castor oil...that's the only bad experience i ever had running a bit of castor in my saito's.Next time i'll try some castrol R that puts hairs on your chest

I was watching the Amazing Race the other night, the only reality show I'll watch, and in their last task before the stopping point one team member had to shotgun a shot of Iceland liquor called the Black Death and the other team member had to shotgun a shot of Cod Liver Oil. I wonder how log it took the Cod Liver Oil to kick in?

Question, the 1.30/1.82 twin left cam has a slash on one side that is a little,over 90 degrees from the normal dot. Clarence Lee does not mention this in his evaluation of the 1.30. And look at the different spacing of the cam lobes, the right cam is a normal .65 cam. I'll have to do some thinkin during assembly. In the picture the left cam is on the right. imagine that.

Picture #3 is about a apart as you can get a 1.30.

My wife watched that show but I pitched a fit about it when I saw the scenes shot in Hanoi that glamorized the memorial of a pond that had the wingtip & tail of a B-52 sticking up out of the water. Very recognizable. They kept showing it every week and when I heard that 5 airmen died on that plane I was really p.o.'ed. She stopped watching it. She was probably afraid I would kick in the TV screen or something.

A Patriot, glad to see it.

I have the new cams, the Boca Bearings, new lifters and a new gasket set for the 1.30.

Jim, I found another set of pipes for the 100, they're in great shape. I'll head them your way in a day or two.

thank you Dave, that is really nice of you, you gave me a great deal and I hope I can return the favor some time

The black death drink sounds like it would floor you quicker than the cod liver oil,at worst with the cod liver oil you would be just crouching for a while,take a good book with you.

ps if tv producers need to add the reality word i think it gives the game away

This is a learn as I go process, I temporarily installed the left cylinder to install the left cam and get the timing correct. As #4 picture shows, the 1.30 and the .65 cam housings are not the same, the 1.30's cam support shaft bore is closer to the gasket surface than the .65's. The cam did not turn with the .65 cam housing in place. Using the timing tool placed the 1.30 left cam with the slash straight down instead of the dot. Picture #3 show the temporary studs to lower the cam housing straight down.

Rudolph Hart

Dave that would be a major fu bah to screw the cam timing up on reassembly for an experienced person like you..I read my saito fa182 twins manual a few years ago and even with the bad translation from japanese to what they call english it's easy to see where the timing marks on left and right cams should be in relation tdc.It's still running the standard saito bearings and tight as,no wiggle in the prop you could put that back together after a carton of emu export,but it might take a bit longer.

ps if you are still struggling have a glass or two of virgin degummed first pour castor,they taught me in real estate classes that you do your best thinking on the toilet first thing in the morning.Don't drink castrol R you'll never make it through the night.

pps awesome bike ride today with mild temps around 31c and that reminds me.Just finished reading a book on organised crime re motorcycle gangs.Two hours south of san francisco is a place called hollister and in july they host around 150.000 bikers of all shades.Did you know there's a gang attached to the hell's angels called "soldiers for Jesus' ?

Good morning Pete, I have no manual, the two cams are very different but I figured it out. There is a better picture of the cam differences her on the page marked 136. http://sceptreflight.com/Model%20Eng...20FA-182T.html

PS, I found this in the 182 instructions, I got it correct.

Figure 10 d. Position the left cam gear timing mark (etched line) at the 3 o’clock position (directly into the crankcase) and secure the left cam gear housing.

SrTelemaster150

90 degrees at the cam is 180 degrees at the crank. That explains the difference in the marks.

The lobe spacing difference is due to the fact that the IN/EX lobes are reversed as far as front to rear. Couple that with the fact that the pushrod orientation angle of 15 degrees is subtracted from the LSA of the right cam while it must be added to the one on the left. That should equal a 30 degree difference in the physical relationship of the IN/EX cam lobes when comparing the 2 cams.

This difference does not occur on the rear cam from an FA-200Ti as the rear cylinder is a mirror image of the front. That is why the FA-200Ti cam will work for counter rotation while the left side twin cams will not.

As far as left/right, I prefer port/starboard to help eliminate confusion. While left/right changes depending on whether one is looking fromthe front/rear, port/starboard never changes.

in your picture, the port cam is on the right.

Thanks Dan, I just took the valves out of the left cylinder again and then used Dupli Color Prep to clean the cylinders, it did an amazing job, even in the 19 degree temperature. They now have their first coat of black paint. I used four scrap glow plugs and wads of masking tape to protect the intake and exhaust ports..

Here is a good picture of what we're discussing.

SrTelemaster150

Those pictures are much easier to visualize.

Both cams will be rotating in a CCW direction as viewed from the rear.

On the PORT cam, the lobe that is pointing at about 9:30 is the exhaust lobe which is located at the front end of the cam. The exhaust tappet is located 15 degrees further in the rotation than the intake tappet, Therefore, the lobe timing must reflect that as 15 degree of advance compared to the intake lobe timing to keep the LSA spec's correct.

On the STARBOARD cam, the exhaust lobe is also pointing to the left in the picture, but now it is @ about 10:30 and is located on the rear end of the cam. Now, the exhaust tappet is located 15 degrees before the intake tappet. Therefore, in order to keep the LSA constant in relation to the other cylinder, the lobe is retarded 30 degrees compared to the PORT exhaust lobe and 15 degrees in relation to the intake lobe on that particular camshaft..

If the tappets were located in a longitudinal line front to rear, the PORT cams lobes would be squeezed 15 degrees closer together and the STARBOARD cams lobes would be spread 15 degrees further apart. The LSAs would be equal then.

As mentioned earlier, the PORT cam must be timed 90 camshaft degrees (180 crankshaft degrees) compared to the STARBOARD cam to reflect the 180/540 firing order.

Thanks again, Bernard supplied me with a link to 1.30 instructions. It seems to be an orphan. The 182 instructions include the 90TS, the 100-T and the 300's but not,the 1.30.

I think Bernard would like to see your explanation for the cam differences, I did not want to take the liberty of cutting and pasting it.

SrTelemaster150

I could be wrong, but I would think that the FA-130T would use the same timing procedure as the FA-182T.

Feel free to cut and paste anything I post on these forums.

Good morning Gentleman, A year ago or maybe a little more I started a build on a SIG Hog-Bipe powered with a Saito FA-91. A few of you mentioned that when I finished it you would like me to post photos, so here you go.

Well couldn’t decide which engine to use a Saito 72 or Saito 56 so I built two planes one with a Saito 72 and one with a Saito 56.

Rudolph Hart

That's a nice looking biplane i specially like the front on shot the way the wings look and have been day dreaming about a pitts special for my fg57.

ps psb? you might as well call yourself 2,4,5-T

All done, new Boca Bearings, new Saito rings, new left intake pipe, new Saito mufflers, already had to .65 size TurboHeaders, two new spray bars, new LS needles, two new cams, newly painted cylinders, just for fun. In making the new throttle linkage I inserted two 3/16" drill bits into the carb venturi's, a perfect fit. The baffle between the carbs was removed for this, the carbs are in perfect sync, the carb's full travel does not use all of the ball,and socket joint motion available. That could have been a problem but I worked it out. All in all it was fun.
