標題: Engine逆轉 !!.... 很請高手賜教!!
我部GXR28Engine... 拉著之後.... 有~30%機會係逆轉 !
而肯定無拉過龍的

恕小弟無知... 個pull starter係單向啤令, 照計唔會好似搖搖咁, 係starter繩捲左捲右既問題 ?

可能係低能問題一則, 但很請解教方法!!
感激不盡!!!!!!! ><

用pull starter係要大力快速的拉,你是不是用錯力。

哦~~~
力度同速度適中la
拉著就百發百中.....
但就唔係次次可以令架車向前行  ><
唉............. ~~

之前都聽人講過 但真係未試過   
你可以check下拉果時個方向岩唔岩, 如果都岩, 再睇睇手拉個單向有無事~

the engine reversely rotation is due to incorrect sparking time ( it is absolutely not due to rotational direction of pull start)....

let me guess, u start the engine, then the engine rotate reversely.  However, when u further pull the throttle, the engine will rotate in correct direction....

please check how many shims u add in the heat sink or missing metal ring between the heat sink and your standard glow plug...all these will cause incorrect sparking time

to Xraylover and MrSH... thanks for your advise man !

Yeah ur are pointing out the situation..... 2 correct starts and followed by 1 xxxxed up start... and so on.....   The chance of being reversely starting the engine is around 30%.

I noticed the flywheel rotates in the correct direction everytime i pull the starter ...... so thats really weird..... everything is rotating in one direction through firing up, but all turns backwards once fired ............

While it is a brand new Inferno GT2 GXR28-SG engine, all settings were stock except an OS glowplug.........

lemme go try the stock plug.... maybe there is diff. between the stock metal ring and the plug ++""
