Motor wouldn’t stay idle. Would seem to die after about running for 20 seconds. I finally get it running after opening the throttle while in neutral and it was putting out a lot of smoke. Recorded this video below. Hopefully someone can tell me what’s wrong.
My 1st check would be fuel pumps. You have two small plastic pumps bolted on port side of block.
Unbolt, leaving fuel lines connected, pump bulb and see if any fuel leaks from pumps.
If so, replace fuel pumps and spark plugs.
After doing some research on the forums. I forgot to mention I put seafoam in. Ended up taking it out and cruising without any issues.
Check the oil linkage and look to see if it is broken
Or adjusted properly. If its fouling the plugs, it can be a bear to start up. Seafoam would just be a temp fix if the oil is out of rig.Originally Posted by javelin90

Also check the lync/sync and look at the throttle plates. When mine was off it works exhibit symptoms like not idle and cut off when in gear.
