CARB ADJUSTMENTS
It is assumed here that if you have a new engine you have already run it at low rpm (4000 maximum) at the rich setting as explained in the instruction manual; this rich low-rpm setting should be used for 15-20 minutes. The final carb mixture settings can then be done as explained below, however 40 - 50 minutes subsequent run time (after the intial 15-20 minutes on a new engine) will probably be necessary to get a final setting with a low idle rpm..
化油器調整
假設您有一個新的引擎您已經按照說明書說明讓它在轉速低於4000轉 RUNIN 15-20分鐘初步磨合。而後40 - 50分鐘的後段磨合後就需要對怠速油真做最後的調整。
INITIAL SETTING FOR A NEW ENGINE OR ONE THAT IS OUT OF ADJUSTMENT:
一個全新引擎或是油針初始直亂掉的調整：
(a)High-speed mixture: Set the main high-speed mixture needle valve to the value recommended in the instructions. If you have no instruction manual about 4 turns out will be OK; this is quite a rich setting and the particular value won’t affect the ability of the engine to start because it is the low-speed mixture setting that affects the starting.
(a)高速調整： 調整主要高速油針轉到說明書建議值。 如果您說明書遺失，請將主油針鎖緊退大約4圈沒關係; 這是相當富油的調整，但不會影響引擎力啟動，因為影響啟動只有低速油針調整。
(b) Low-Speed Mixture: The low-speed needle should already be set about right (ie somewhat rich) for new engines as they come out of the box. If unsure about the initial setting adjust the needle so that the top is flush with the throttle arm level; this is good starting point for all engines except the Saito-30. For the Saito-30 turn the low-speed mixture all the way in, then turn it out 4 1/2 turns; this is a good starting point for that engine.
(b)低速調整： 新的引擎在出廠前低速油針都調整在比較富油的下，當他們從箱子出來。 如果沒有把握的話請不要調整這根針，萬一亂掉的話請退低速油針跟外框切齊; 這是所有引擎的好起始點， Saito-30除外。 Saito-30低速調整一直轉到底退4 1/2圈; 這是那個引擎的一個好起點。
For the following procedures a tachometer is highly recommended although not absolutely necessary for setting the final carb mixture settings. If it is your first four-stroke engine you should get a tachometer. before you go any further.
最後的化油器混合比調整，建議您使用轉速表最為依據。 如果它是您沒有轉速表請準備一個。 |
