Other manufactures services centers have done the right thing and their turn arround time has been 2 weeks at most, I was extremly explicitd and elaborated a lot my engine behavior to ACE in writng when I sended the engine.
Sometimes they do the wrong thing and take longer and sometimes they don't fix the problem, I have heard horror stories from all of them from time to time. Though ACE does take a couple of weeks longer than most.
Don't you think they should check the o-ring?
If there is no air leak there is no reason to remove the carb and check it. Pro's know its best not to take apart something that is working. A score does not mean it was leaking, in fact it could have been scored on disassembly.
And no, the manifold-carb mismatch is not a common problem in other quality brands
Ah, but it has shown to be very common, especially with Magnum. In fact it has some benficial gain in providing turbulance and atomization of fuel. There is often a mismatch between the head and manifold as well, though I am not sure there is any advantage there.
How you know if the o-ring you get on the auto parts store resitst GLOW fuel?
Because cars have been made to resist fuel containing alcohol for almost two decades now.
And if you pay attencion when you read my post will realize I don't have a problem anymore only a lemon that became a lime.
You still have a problem, you just decided not to deal with it.
I'm sorry but I just get used to quality engines that work flawlessly from the begining, even if a have to pay more, lesson leraned (save on the penny and spend on the dollar).
All of my TT engines have had equal quality to my OS engines except for a tendancy toward loose screws. I agree the hobby services are worse. My TT .91 FS worked better than my OS .91 FS except that it needed a longer break in. I suspect (because you have not told us what the problem was) that your problem was something else. It may have been a fuel system problem, such as a leakey fuel line or tank, or it needed more break in time, or you simply didn't understand some differance in that engine and the engines you had before. In fact I think this has been the first negative report I have seen on that engine.
But then again there are lemons from OS and others so this could also be a lemon.
