Got a buddy with a ST 90 and a 'OS' D7 carb...here is a pic of the carb, I don't remember a D7 looking like this....Engine just doesn't like to run....

that's because they took out a good carb and replaced it with junk!!!

I'd put the SuperTigre carb back on it. They work amazingly well if you read the instructions on tuning them.

That may be, I haven't gotten a reply yet. That's okay - to move ahead, I found a parts engine with a good carb on it. I should have that engine in a few days - it's coming from the other side of the country.

I'll see if he still has that carb...there must have been a reason he took it off to begin with.

Just to show you never can tell with ST carbs, this is the carb from my NIB ST S45 ringed. Same idle needle as mentioned but a similar style barrel type main needle.

My S90K carburetor has the same brass features on the needle valves as your S45 ring engine does, but my other ST engines have different embellishments (if you will). Pictured first is my S90K, GS45/G51, and S29 Carburetors. I have an S45 ring coming in the mail.

Here is a picture of the idle mixture needle from the S40 (19.5mm - too short), and the idle mixture needle from my S90K (26mm - the proper length for the S40 carburetor as well). At some point, someone replaced the needle in this S40 with the incorrect idle mixture needle.

I never knew there was a CLUB SUPER TIGRE but your thread made the RCU Top 15 on the home page. Thought you guys might like this pick of my ST 60x. Nothing sexier than Super Tigre Serie X with header.

That's pretty cool - but I have to ask why the Perry carb?

It was a pump package option from the vendor available back in the 80's for piped ballistic pattern acft of the day. This was a 'Before' pic...

I had a feeling there was a big mouth in the carb and a pump nearby. A lot of folks swap another brand carb in for the ST carb which usually ends up in a downgrade in performance. A big pump carb and pump is a little different story on the right engine. You have a beaut there!

Thanks.
That was a 30 year old barn-find 'Tiporare' I restored and flew in classic pattern meets for a few years. But as I said, those were 'before' pics. I lost it in Lancaster Calif last summer. And the ST was junked too...

That's the Tiporare, isn't it? I want one!!!

That's a major bummer. Sorry to hear that.

I have a Series X 60 for parts or rebuild if anyone is interested. Needs a ring and muffler.

I could use some help finding the bore/stroke specs for all the big Tigres. I've looked all over, but can't find the information. Thanks!!

Thanks Dave, I'd forgotten about that resource! I actually found an info sheet in the box one of my engines came in, and it lists all of the information I was looking for.

Has anyone ever tore a ringed ST down to rebuild it or repair it and find the ring gap to be in excess of .010"? I tore an S90 down to clean it up and fix a leaky gasket and noticed the compression was lousy. Checked the ring gap and found it to me .012"!! I have a Bowman ring on hand and the ring gap of it was .0015". Wow that's a difference. I have the main engine parts in an antifreeze bath currently.
