:frustration:I have an 91' Hi Jet that I just got and I can't keep it running. It will start and run for a while and then it will start choking out and die. Does anyone have any advice
Certainly I would check the plugs, cap and rotor...but It sounds like a fuel problem. Check/change fuel filter. It could be a fuel pump problem. Verify you are getting fuel to the carb. That's the first things I would be checking. LOL,
Engine stopping on '91 Hijet Check fuel filter under box mainly inlet and outlet nipples I had an old Datsun pu and inlet nipple was squeezed almost closed when the engine was runnig it woould cause vapor lock in filter, a few min. stopped and would start again and run just fine for few min.
the fuel filter seems to stop up a lot. i think that the trash in the gas tank get stirred up in shipping. cheap part , just match it to a new one off the shelf. doesn't have to be exact , just have the same size hose fittings.
WIX 33001 is the cross over that I have gleened for the internet as a replacement for this. About $4.00 at the autoparts place./
Does it run with your foot on the gas? If it's not a fuel delivery problem, it may be the low idle screw. There are two on a hijet of this vintage, one in front, one in back. I've had 2 in the past where the motor raced like crazy or acted like yours. It seemed like someone tinkered with both and started turning screws until something affected the way the truck ran. They start at high idle (screw in the back) then drop down onto a second screw on a cam in the front (I May have this back wards, but you get the idea). Start the truck (cold) and see if the rear adjustment affects idle. It should. Then as it warms up, work the front screw to an acceptable idle level. Just one theory, make sure you have fuel and vacuum lines are all hooked up and not cracked. Jim minitruckoutlet.com
