Ok I don't drive interstate much. But here's the issue
Around town is fine. When I get on the interstate. 15-45 minute drives. Often I get loud chatter at cruise. It's loud and sounds like ch.ch.ch ch.ch lol. Now this morning it did it. And when I got off the interstate it died. And wouldn't crank up. I pushed it and clutch (kick) started it . After I did that it ran but idled a little off. I drove it another Mile to work and it was idling like it was ported, heap brap brap. :?

Now usually when I have this issue I add premix to the tank and it seemed to not have issues. Is thereany chance my oil injectors are clogged or inadequate flowing ?

 

Did the knocking speed vary with vehicle speed or engine speed?

This probably isn't the issue, but just in case... are all your spark plugs and leads attached?

 

Not really , it was a constant chatter. And when it started. No matter how much throttle it would not accelerate only would decerate.... And when it decelrated it wasn't fast. Just lowered down rpm slowly. .
