Starts fine, runs good until it gets hot (normally hot). Then, like light switch, it starts to backfire, runs rough, and stalls. On restart it continues to misbehave. If I wait until it cools off, all is good again. Takes about 20 minutes of running before it acts up.
I bought this used, and found someone had bent the choke blade...I thought that was it! But cleaned the carb and straightened the choke situation and same. It does start better now...
The guy I bought it from did disclose that it had this problem, but didn't know how to fix.
Swapped the electric fuel pump to eliminate that.
Ensured the fuel filter was good.
Blew air back into the tank to ensure line was not clogged. Cleaned debris out of the tank. Fresh Fuel.
The Oil pressure sensors were miswired according to the schematic. I think that's now OK. From the choke blade situation, a hack has been working on this in history.
Propane tanks are shut off. I think it does same while on propane.
I noticed that inside of the tank, the fuel inlet seems to be "hinged" at the end in the tank...what could that be for? Interested to see if by chance this is clogging up the works. I will also next try to run it with the gas tank loose in case the tank vent is clogged.
I read posts about a revised ECU for the LRG-425...Hoping that isn't what I need (cost). But want to understand why Ford offered that up and to fix what symptoms. Does anyone have the part number of the kit or hopefully a link to the TSB / info on the upgrade?
In reading I see that the coolant temp, combination of the oil pressure sensors changes the timing curve within the ECU. That's why I am wondering if the revised ECU addresses this issue.
I replaced the flywheel / starter from a Ford Ranger. Exact match. Damaged I am sure from trying to restart when hot. Hoping the ECU also comes from a Ranger (cost)...any ideas?
Hard to isolate fuel from ignition as it usually happens when I am up in the basket
Thoughts?
