Default Super Tigre .60 Bluehead

I have acquired used a Super Tigre .60 Bluehead that I am planning on using in one of my vintage pattern airplanes. It appears in very good condition but came with one of those old SEMCO mufflers. I would like to find a source of parts for this old engine so I can keep it up and running. I specifically would like to have a new sleeve/ring and maybe a piston, and an original muffler. Bearings I can always get from Bocca and needles I can get from Higley so I am OK there. I also found in the box a spare head and piston, but they are different from the one already on the engine. The head is blue but the piston does not have a baffle and the head does not have the cutout for the baffle. Was this a hop up part back then?
I would really like to restore this engine to like new condition so any help would be appreciated.
A parts breakdown with original part #'s would really help also.

I had one of these until a couple months ago and the muffler bolt spacing was the same as the current 61's. You can get rings from Frank Bowman. Bearings from Boca.

The sleeve on these old ones were Chrome plated from my experience. Even on the newer ones that were not chromed, the sleeve was hard and was seldom damaged.

Some of these had PDP (Perry Directional Porting) ports in them. You can see these by looking in the exhaust on each side of the exhaust port. They were a semi Schnurle ported engine.

The G60 series, and it's varients, were real popular in the 70' & 80's. There are more variations than you can shake a stick at. There are still several Blue Heads in this area.

enjoy,

Jim

All Super Tigre G-60's used baffleless pistons/heads. It wasn't quite schnuerle porting, but it worked very well and produced a fair amount of power.

Some were even offered with PDP porting mods. I have two G-60's at the moment myself and I love the engines. They are among my favorite glow engines ever made/owned/flown.

As the other poster stated, there were many different versions of this engine. My favorite is the ABC/ringed version. It just keeps on running and producing gobs of power, year after year.

I don't know of any parts sources since I am just getting back in to the hobby again after a two year absence. If you do find some sources, please be so kind as to post them here. TIA

As you use a Blue Head, the blue get lighter and lighter until you can barely see it. How are you going to make your head blue again?

Enjoy,

Actually I have been experimenting with that on other engines. I found a paint made for brake calipers at my local auto parts store. I painted the muffler on one of my .25 LA engines and it is a close match to the blue that O.S. uses. Got several gallons of fuel through the engine and the muffler looks just like the day I painted it.
As for the alternate piston, I was informed that piston and head were to be used with a Perry Carb and pump that replaced the back plate. The gentleman that I got it from indicated he purchased new in 1972 (dated receipt in box.)
The one in the engine now definitely has a baffle and the blue head is cut to match.
Who is Frank Bowman and how do I contact him?

$11 for one ring or $19.50 for two shipped US up through 1" bore >1" is $12/$21.50

There are several designs on the G60 series, so you will probably have to measure the thickness?

enjoy,

The heads on the Blue Head 60's were Anodized. They were not painted.

On the G60's, you'll hear people talking about the light case and heavy case versions. I've been around both kinds of cases broken and the thickness is the same. The difference is some extra webbing and holes for the muffler.

Yes mine is anodized but I was thinking the paint would be an inexpensive alternative. This a picture of the muffler I painted with considerable time on it. It really holds up well to the heat.
Thanks for the contact for the rings.

Your muffler sure looks nice.

You will ruin the value of your ST if you paint the head. It may also cause the engine to over heat.

As built up as the area where you live is , there's someplace that can anodize it.

Enjot,

Jim

Not all G-60 Blueheads were loop or PDP ported. I have one with STS porting.

Now you are going to need to explain STS porting?

One of the things that made the Blue Head what it was, was that it never used a baffled piston and matching head.

Are you sure that these were not aftermarket parts that were intended to make the engine competitive in some class requiring cross flow engines?

My memory is far from perfect, but I hope it isn't this bad! <G>

I even own a predecessor of the Blue Head that does not have a baffled piston.

just a quick observation - that carb spraybar appears rotated out of position quite a bit. You may want to check the alignment.

Ed this was the way the engine came to me.
Bob, yea the spray bar is out of wack, I had the carb apart to clean it and have not locked everything back into place yet. Everything is just finger tight in case I want to open it up.

The G60 Bluehead came in several flavors. Looped scavagened, loop scavagened with PDP porting, and STS porting. STS porting was Supertigre's own porting which did not use a baffle and had ports directly across from the exhaust, but were angled up toward the cylinder head. They also came ringed and ABC.

Well, I guess this just demonstrates that one is never too old to learn.

My G-60, and the one that I prefer the most, so far, is the ABC ringed version, but I would not refuse to accept any version, if you know what I mean.

Default RE: Super Tigre .60 Bluehead

OK here is another photo of the pistons and sleeves I got with the engine. One is the chrome cylinder, ringed piston.(This was in the engine when I got it) The extra one in the box is an ABC set up. I was told that the extra cylinder was to be used with the Perry pump that replaces the entire back plate and the Perry Carb. Both of these parts were also in the box as was a head that does not have the baffle cut out. Also just FYI this engine is tapped for and has in the box, an exhaust damper. (A butterfly that attaches to the throttle linkage and rotates back and forth to cover the exhaust port.)
My question here is what type of porting do I have here? You have referred to several types and I want to know what I am working with.
Also, the back plate on this engine has a slight dimple cut into it. Looking at the engine from the rear I believe this dimple should be positioned in the upper left hand corner, but I am not positive. Could you look at yours and let me know how it should be positioned?

We are talking about the ringed one...

If you look inside the sleeve and it's a PDP engine, there will be two vertical grooves inside the sleeve between the exhaust and intake ports on the front inside and two more on the rear inside. This is kind of a partial Schnurle set up. They run pretty good.

If your ringed sleeve doesn't have these little grooves, it's a plain one and not PDP.

Apparently the ABC one has what ST called STS porting?

Enjoy,

Jim

In trying to study the pictures, the ABC one looks like the front-rear intake ports angle towards the exhaust and not the intake boost port?

Somebody help out here?

Well that's interesting. The top liner with the STS is also PDP! I'd always thought the PDP was only for baffled pistons to help clear exhaust gas from the Hell's Kitchen area....which obviously a flat top piston doesn't have.
