What caused your IP to start acting up? Could you send me the guys phone number so I could pick his brain?
Tonight’s summary:
Checked the fuel tank cap, vent hole was clear, filter material long gone.
Disconnected the line front the tank to the filter and blew air through it again.
Removed filter again, fuel looked good in it and it was full. Blew air through both sides of filter housing.
Removed line from filter to injection pump and blew air through it and cleaned it.
Confirmed good fuel flow to filter. When I put the filter on I had to use the hand priming pump to get fuel to keep flowing through the filter housing outlet, otherwise it wouldn’t naturally flow through. Not even a drip. But with the oulet line removed each pump of the hand primer gave a good blast. Any concern there with it not flowing through the filter housing once the filter was primed?
So after all that it is still doing the same thing. I would run it a few minutes and it would bog down. I did remove the fuel cap just to check if that was it.
The fuel pressure gauge never drops except when I throttle down to very low idle or shut it off.
when I go to reprime the system after a short shut down I get air pressure, and then the fuel at first looks foamy with small bubbles until it clears.
when it bogged down I idled down and the idle sounded rough. It sounds good when I rev up but something just sounds off in the idle. I will try to post some video but I know engine sounds never sound the same in phone videos. But anyways, after I let it idle awhile it starts to sound good and then I can run it hard for a few minutes again, then it starts bogging, like I gave the fuel system a chance to catch up.
Maybe I’m a goober, but do I need to bleed at the injectors? With it running so good for the 10 or so minutes after re-priming I figured that doesnt need done.
All this seemingly because I let it run out of fuel once!!! Gah!!!
Could something be going on with a pressure relief valve?
