我個引擎

full 雞收油後有變速聲,咁我就比大D 細油針(反時針),比到好大也一樣有變速聲,之後怠速到full 雞時又有因油多而唔可以好快到極速
E + 就變成"收油後有變速聲"+ "full 雞時因油多而唔可以好快到極速" 兩個問題
左 set 右 set 都 set 唔到,請問有經驗人事我架機咩事? 太 old 了嗎?
PS: 起動時好容易就起動到 , 我估不是火咀問題吧

年紀大,機器壞......

the idle speed is too high...lean the idle speed needle (not slow speed needle)

25% 電油

check your servo link ...

To me, I lean the idle speed as low as possible.....

回壓侯太短

給你看怠速位置? 大約 5分1 吧

回壓侯長短有關係嗎? 長 D 好 D ? 不是短一點才夠力壓回去嗎? <<<<<<我估
如果長 D 好 D 請問原理是什麼?

回壓太長，不夠壓力，令油門(機器)反應慢

回壓太短，壓力太大，令油門會追油(縮油后會慢慢收油)

你可參考其他 c hing 有冇人的回壓侯有你咁短!!

應該唔會係回壓侯
較大主油針副油收細試下

Tomatchinhk:

there are too many different ideas in this forum.  The most funny is that the idea is contradict to each other...I recommend u to find the answer by yourself...

Your engine shall include four needles for adjustment....1st: idle needle, 2nd slow needle, 3rd middle needle, 4th main needle....first of all, please make sure u select the right needle for adjustment.  As shown on your photo "01.jpg", this needle is middle needle.  Most the time, we just set this needle to be flated with the carbutor body....(Tips: we never touch this needle and even touch, never adjust more than half cycle)

Yes, your back pressure silicone tube is relatively short.  But your problem should not be due to this reason.  If u just lengthen the tube without do anything to the root of the problem, your situation will become worst....

Apart from tha above, please tell which nitro u ar using and how many shims u added between the heatsink and crankcase....

check the pipe back pressure hole if it is blocked by the putty.

我英文不太好希望沒會錯意
你是指散熱頂和引擎中間的壓力墊片吧? 我是沒有安裝的,因為機器已好舊(但小耍),如果加要加多少 mm ?

圖片 01 的中速針我也沒設定過,只是扭到和出面平就算

主針已去到 4,5個圈,再大D 不怕太吃油嗎?

pipe back 是什麼? 是指回壓油喉? 如果是的話佢沒閉塞

try try 0.3mm shim

試到我沒心機
