轉用Tornado后engine 過熱

今日轉用Tornado 25% for competition, 副picco .21熱到13x度, 之前個星期用过Cosmo 20%同舊款Tornado 25% (唔記得左系邊種), 最熱都系得90幾度

莫非以前dTornado系10.5% 油份, now 得8.5%所以熱？ 是否應該加0.1mm盤頭介子呢？而且 現在發現比較容易死火，lean了副針，加大少少idle好似好左，不過就系熱, 追油

use OS #8

Nitro成份多了要較冷的火頭

唔放針情況下, Competition 8.5% oil content轉數會比10.5%高. 放返少少大針應該OK.
我部 Speed大機用OS7 plug, tornado competition 25%都係105度.
易死火收少少細ok, 不過高轉可能lean過頭

收副針會影響大針高轉lean嘎？

ching, the second needle will not affect fuel injection during high rpm provided that: tip of small needle has already escaped from the hole of fuel jet at the high rpm concerned.
example 1: when the slide valve is at full throtte position and the small needle tip is still inside the hole of fuel jet, the small needle is affecting fuel injection at full rpm
example 2: when the slide valve is at any throtte position but the small needle tip is outside the fuel jet, the small needle is doing nothing with the jet and thus the jet depends only on adjustment of big needle only.
