I feel like a broken record. I'm still having problems with my bf130 and it is definitely fuel related. The problem is when it is under load it will begin to lean out and will stall. There are no problem if I take it out of gear and increase the revs to 4k rpm, it only happens when it is under load and then it cuts out. There are no sounding alarms when this happens.
I have replaced:
fuel fill/vent hose
feed hoses from gas tank to water separator
put new water separator filter in it and lubed o rings.
replaced primer bulb with johnsons bulb
replaced low and high pressure fuel filters inside the engine
replaced vapor separator filter
The bulb will get very firm when I pump it (johnson bulb) but when the engine begins to stall if we pump the bulb it will be okay for a few minutes. Sometimes the engine will correct itself and will run fine for 15 minutes and then might need a few pumps. Since I need to pump the bulb would that indicate that the fuel pump is bad? Is it possible for the fuel pump to only act up on higher rpms during demand and not during start up? The motor starts up and idles fine.
I have run a clear piece of tubing from the external fuel/water separator and can see air coming out a bit where it leaves the filter. When I pump it hard the air goes through the bulb and disappears, but when the engine is running under load it does not appear to have any air going through the line, it stays on top where it just leaves the filter. Is that normal?
As a last resort I'm going to replace the entire external fuel/water separator and sight bowl with a new one since the sight bowl is old. I am also going to change the spark plugs and thermostats even though it seems to be a fuel feed problem and not a spark or temperature problem.
I'm scared to go to the dealer because when I mentioned the problems he said that it could be a bad fuel rail that needed to replaced or a bad head and when he quoted me the price it was very high. I know my engine had a replaced head under warranty before I bought it. I'm skeptical to take it in because the problem is sporadic and I think they will just keep changing pieces out or charge me to have the fuel rail or fuel pump changed out and I'm not sure exactly what the problem is.
