Hi Dave! I just placed a Saito parts order with Advantage Hobby. The parts were slightly cheaper than Horizon and the shipping was $4.99 instead of $8.99. I was immediately sold.....

Advantage also has free shipping for orders $50 & more while Horizon's minimum is $100.

I'll address everybody oin order, Bob the new gaskets came from WholeSale Trains/Lantz's Hobby Shop today, I'll head a set your way tomorrow if possible.

Thanks Pete, it is a good result, the TH is actually laying right beside the 1.00. That re-bar would make a great chicken stick. By the looks of the bent one I already tried it.

Yeah Ernie, we're going to have to find alternatives to HH, they seem to have become slackers now a days.

Dan, I used you rubber band method holding the crank at TDC, worked like a charm, I make shifted a cam holder from a small Phillips Head screw driver and a section of heat shrink..

I also made a big block cam holder from a small square of brass shim stock. You can cut a "U" shaped notch the width of the cam gear teeth root & slide it over the cam gear. Just a little handier than the exacto knife method.

My small block cam holder is similar to yours except I used an allen key W/shrink tube.

The cam holder thing. In the little red book on Saito engines put out by the old RCM magazine there is a neat set of diagrams for a tool to do this. Which it does very well. I have made and "lost" a number of these over the years and once the new workshop is set I will make a couple more putting one in the box of tools I allow people to borrow,
On the workshop front, we get access to the new property and once a couple of mods to the house are completed (like removing a combustion stove) I will be able to start the construction of the new "retreat". Thank heaven

It takes 2 different tools. One for the FA50 based valve train & another for the FA120S based big block valve train.

I have the "reprint" of that book. It's just copied out on copy paper now days. I got it a couple of years ago. Lots of good infromation like valve spring height, etc..

Hey, we're talking RCM Modeler here. I was luckey to get what I got from what I here. They were always real nice to me & even sent me plans for a 48" 3 channel glider free of charge when I told them it was for my grand daughter. Seems lately they are MIA.

I guess you're talking about the plans service. The mag folded right after I renewed my subscription. Grrrr...

BLW, a friend ordered 2 alum. backplates and gave me one. I think he got it from Horizon. They should come with the gasket and with new screws for the carb mount, but..... no. Can anyone tell me what the symptoms are when a Saito carb begins to need a new set of o-rings / rebuild? My 82 has been around probably 10 years now but does not have real high hours on it or anything. Still seems to run good but just wondering what to expect with the carb. (I do replace the intake manifold o-ring occasionally) Also what things are hard on the carb and o-rings? For example oiling the engine up real good with regular oil and it runs down into the carb. Doesn't regular oil tend to swell the o-rings up? Thanks guys.

You'll get all sorts of answers on what brand of aro to use,or even not to bother.I use automatic transmission fluid.

Had a hard to consistently tune 82 once.Turned out it was the tiny little o ring in the main needle tube,it's a so and so to get out,or in at first,good thing i had plenty of spares.Finally made a special tool for it.There's two o rings on that inlet tube

Jumped on the duke first thing this morning and with a few mates headed up into the hills east of here for lunch at the noble falls tavern..best steaks in the west.We all came back down dodging lycra bandits and wayward motorists..ahh life can be good.

Hi Old Fart.
I have been to Perth maybe 1/2 dozen times while on deployment on several US navy ships. Perth was one pf my 2 most favorite places get some R&R, The other being Haifa Israel. Found it hard to spend my own money both places. Folks just as friendly as could be. Being married had to be extra careful because .... Well you can infer the why.

Not a blessed thing to do with Saitos. Just wanted to say Hi and thank one of the good folk from there for the great times I had. Dang sure wish I could afford to return to both places.

God bless ya

Ken

Thanks, Ernie. Those have been out of stock for years now at HH. Yep, you just get the backplate rather than an upgrade kit. I ordered all the same extras you did. Big thanks to W8YE for the advice on the screws.

Leaking o rings mean lean runs. The old style plastic backplate meant intermittent leaning out shortly after you thought you had things fixed and set right. The 82 is supposed to be a sweetheart engine.

I stopped worrying about using the viton o rings a while back when I needed one and had to use a hardware store one. Never had any problems to date.

As I think I have said before when you are looking for "o" rings if you can't get them in the water sprinkler section of your hardware store try the local small engine repair place or my prefered option the local a/c parts provider. Aviall is my preferred shop with lots of Parker "o" rings and if you are nice they might even give you a guage to size them

Whoever said the aluminum backplates are no big deal, just a backplate. Yes, I sure do agree with that but they are nicely machined and lovely, and there should be less vibration going up to the intake manifold o-ring. I use ATF for ARO oil also (mixed with air tool oil) but I think it still swells up silicone o-rings. How many types of material are used in o-rings? Are there silicon based and non-silicone based, that ARO would not affect? Is the swelling up a big deal really? I noticed when I got ARO into a couple of carbs that the main needle got really hard to turn for a while but then went back to normal with use and running.

I never heard of silicone based "O" rings. Neoprene & viton, but not silicone.

These metal backplates have been in stock at Horizon every month since April 2010. http://www.horizonhobby.com/products/SAI82B17
