I did the remaining things- atrificially heated the head with a hair drier till the point I couldnt touch it. There was no loss in compression, it does that randomly. But, I tried to turn the screws, none turned, only the allen wrench slipped on the screw head (I am going to have fun opening it)

I replaced the fuel tank (as per the club member's suggestion) to a Sullivian 320cc tank (I had bought it last year after the deadsticking started). It is larger than what I was using so the CG will go off but if it works its worth adding a bit of tail weight later. I also put in an OS bubbless clunk as you suggested. Since the tank is soft, I was able to add extra padding everywhere so the tank is snug now (not that the earlier tank wasnt). This is now my most expensive tank setup yet.

I ran it at idle, thats about the most I can do at home. Its now nearly 12.30am, this is most likely the 10th or 15th consecutive day that I have sat up this late to set it up, I can do no more of this.[:@][:@]

I dont have a 12x6[&o]. Since the recommended is 12x8- 13x6, I have 11x9, 12x4, 12x8, 13x4, 13x6 and for other engines 14x4, 14x6, 14x8, 15x4, 16x8, 17x4, 18x6. Guess the remaining are too big. I had tried the 12x4 on an earlier 55ax engine and it screams (I dont have the baffle in, no scope to put that in now). There is no 12x6 in stock anywhere locally and I cant order from Tower or Singapore just yet. There is a 13.5x4 MAS Formula series, a 12.25x3.75 APC 3D prop, 13x6 APC pattern prop, thats it. So please suggest which to put in.
