I just buy C5 prerun!, my friend say it still need more break in (more 5 tanks)! and need to add more 0.1 shim, because in my country out side temp is 32'C. Is that true? I use tornado fuel 25% nitro! Can C5 standard beat C3 Rody '98 or JP Pro'99? Thanks.

2 more tanks should do the job normally, of course you need to give the engine a little more time to go to peak-power, so go gently to the 100% possible. Normally no need to add extra head-shims if you use 25% nitro, however if you want to play it safe you can always add 1 shim of 0.1mm but it will take a little of your power but makes the carburetor setting easier.
Why when I richen the main needle (WS7) the engine suddenly die at full throttel (on the ground only ) or before entering 1st corner (release throttel) , and disappear when i close main needle, but engine get to hot 260'F (Exergen)?

I cannot give you the exact temperature for the engine, should be around 220F - 240F
Concerning the engine stalling after you have richened-up the main-needle, it could be your engine is too rich on the idle-needle, which can make your engine stall more easily.
