引擎上唔到油, 點算?

引擎著左之後就上唔到油, 油針已經放大, 但仍無改善。
謝謝.

油喉有冇塞/油缸蓋有冇合實以上都有可能上唔到油!

油缸同油喉都是新的, 化油器試過無塞。

有無裝條喉由排氣喉至油箱.

有裝回壓喉

如果上唔到油應該連機都著唔到,你係著咗機上唔到油先死火定上唔到油著唔到機？前者未必係上唔到油,而係被油整熄？

系著左機上唔到油先死火，聽得出引擎好Lean，吊下吊下甘。
不過其實著機都好難，因為油缸D油上唔到 (要倒轉架車, 油缸level高過部engine, 才勉強上到D) (check 過無 airleak).

你睇真D啦！好似油底位條喉接左喎？

無"接"架...只是角度問題.

請師兄幫幫忙, 唔該.

回壓喉長得滯同支批咀長同貼地會唔會有影響?

試試檢查一下油箱泵油支桿有無”kick”住，唔識自動彈返上去而令到出油孔塞住上唔到油！

回復 wilzchau 的帖子

正常副機上到油係因為入面既活塞運動產生負壓而將油吸上嚟,如果你要倒轉部車等啲油高過engine先著到,咁好有可能係入面既油路阻塞了,所以當啲油灌入去就著到,放平就即刻死火,你試下鬆咗大針出嚟,由嗰度同油喉入油位滴啲油入去,睇下滴油會唔會由入風位出番嚟,如果唔會咁即係嗰度塞咗啦

副engine 玩過？仲有無壓縮？

會唔會油針過大呀 =冇左真空原理

換返透明油喉會唔會睇得清楚d呀? 著咗機狂油泵上油會唔會死先?

hi, i am a new member and would like to help:-
1. without the glow plug battery, plug the exhaust hole and pull the engine to see if fuel goes into the engine. if ok then start your engine as usual. if not ok, see step 2 below.
2. without the glow plug battery, plug the exhaust hole as well as the air intake hole and pull the engine to see if fuel goes into the engine. if ok then start your engine as usual. if not ok, there should be some serious sealing problem between connections in the engine. observe if there is any fuel leakage when you pull the engine and check the seal at the leakage location.

有個直接方法，換過架！

拎出黎比啲師兄睇下啦! 唔着可以好多原因...
