I have a ex100-5 since 6 month, when i bought it it runs perfect, Suddenly its having problem about slow running and engine stalls, When i pull liver in small amount then work slowly but when i pull full liver engine totally stalls and smoke black badly, then when i leave the liver engine come back fully fine, Can anyone solve this? Thank you
Fuel filters or fuel supply issues where the fuel lin is plugged between the tank and the engine. Most likely in a banjo fitting.
I have checked fuel line, Its fine
Need a little more history on the issue. A few places to check for proper fuel flow and/or pressure. When we're the fuel filters last changed? When was the air filter last changed? Is the fuel cap venting properly? Your problem sure seems like a fuel supply issue. A plugged air filter can cause similar issues. It could be a combination of both.
If it's blowing black smoke while it's stalling, I'd guess it's a hydraulic problem rather than a fuel shortage problem. I don't know the hydraulics so I can't help you there. Did you inspect the banjo bolt? do you understand "banjo bolt"? could be an americanism.
