That's funny! This is the second time this week I've seen the same prob. My friends carb came apart the same way in his Losi 8. IDK!
I do know the thermo coupler is getting stuck in the case due to over tighting the "pinch bolt". I've had that prob before and bought a new one and used some 2 part JB weld to install on the old carb. Just snug up the pinch bolt and use some Lucky 7 Engine Sealent around the base of your carb. Good Luck

does the part which came off fit back in or is it to tight to fit, reason i ask is i actually saw a carb body listed in spares section on a site yesterday while i was looking for bits for mine, so wondered if you were to strip your carb body and hsn assemblies right down so you are left with the 2 blocks maybe if you heated the carb body and froze the other section you may be able to fuse them back together again, just an idea as it seems this is how they are assembled at some point anyway, you may get away with it?? nothing to lose i suppose

Well they fit right back together with no effort at all, so I assume I need like green loctite or something But for me these carbs are not worth repair because I do not want to loose a race because of the same problem. Sure I might get a few more tanks out of it, but not worth the risk.

I'm more concerned about finding the cause as that V-Spec runs really good and hasn't much run time on it. I refuse to blow another carb, so it is just sitting and waiting until I feel it is safe to run it again.

BTW, how do I get that thermal sleeve out of the engine? I got stuck in there after removing the last carb.

It looks to me like you might have been using a wrench or pliers to twist the carb...the thermal isolator is missing or probably still in the crankcase.
The problem...as you see...is the main and mid needle holder is pressed into the carb body and isn't designed to handle any kind of twisting.

You can reassemble the carb using green loctite intended for retention (609).

Another option...an perhaps GP (OS customer service) might do this for you as a warranty...is to replace the carb body with the new 1 piece carb body that now comes with the OS Speed and maybe the .28 too. (OS p/n 23818135).
