I've got a brand new Thunder Tiger .91 FS that I bought on eBay and I've got a LOT of questions about it. Please, anybody, answer whichever or how many of the questions you have time for.

Quick background: I put on a wooden 12x6 and started the engine and the first time it started right up. The second time it (in retrospect) backfired and kicked the prop loose. But after that it seemed to have NO compression hand-turning it, so I figured, uh-oh, I broke something. I took the top end apart and it looked fine, so I put it back together and although while turning the prop over manually it seems to have very little or no compression, it started right up.

So I broke the engine in by running 2 tanks through alternating long rich and short lean periods, gradually increasing the lean and decreasing the rich. BTW I do NOT have the choke assembly on, but will put that on and see if it solves any of my issues. So, my issues, in order of importance:
[ul][*] I did not get a manual with it. I have downloaded manuals for OS and Magnum .91 FS's and they're very similar (to each other), but of course I don't know how similar they would be to the TT because I can't find a download for the TT. Anyone have one I can beg, borrow, steal, or download?[*] The engine runs WOT at around 10,500 but is VERY LOUD. I was at the field with 4 or 5 other 4S flyers, and this thing was off the scale in terms of loudness. The sound is also of a different quality: brack-brack-brack-brack rather than brup-brup-brup-brup, if you get my drift. Is an issue with the muffler - is it known to be crappy? Or might this really loud, brackety-brackety sound indicate something else wrong?[*] The engine vibrates like nothing I've ever seen before. The clunk bounces around in the tank so bad that at about 1/3 full I start to get bubbles in the line. I'm afraid it'll shake itself right off the firewall. I've checked the prop balance (without a prop balancer - I put it on a razor blade and it seems the balance point is right in the middle of the hole). Any ideas?[*] It won't idle. AT ALL. I'm hoping someone will point me to a manual, so I can get the low-end mixture default settings, and perhaps the choke asbly will help. I've also found on this forum the valve timing and clearance settings, so will check that. Any other suggestions?
[/ul]

I don't want to tire you with my other smaller issues (like NO valve cover gasket - I'll throw some permatex in there) until I get these major ones resolved. I'm confident that this engine will work eventually, but it sure is a challenge for a newbie. Thanks in advance for any advice / help.
