problems with my 86 pickup- 22r vapor lock?

[ttFJC]

Ok guys. Seems like I’m having a bit of trouble with the gambler trok in the heat. 1986 pickup 22r carbonated
Truck starts up fine, drives just far enough to make it to the dog park just about three miles away and then won’t start u till it’s had at least half an hour to cool off. Today it died on me 100yards before the parking lot and same thing wouldn’t start back up till it cooled off then it died as I was rolling into my parking spot at my condo.

What do you carb guys know about preventing this. Do I need a new fuel pump or something? Rebuilt carb? I got a gas cap and poured some Heet fuel and carb cleaner into the tank but didn’t seem to help. Also haven’t driven it enough to work the heet into the fuel lines yet. Someone told me to wrap the fuel lines in tin foil.

right now it starts up fine, gets up to operating temp, then after a while is starts running on three cylinders and eventually dies. I havent tried driving it.

Any suggestions?


trying to keep it cheep as possible. this is a Gambler 500 that i legit only paid $500 for so staying true to the feeling, im not gonna just slap a new weber on it. no one seems to know about carbs anymore. at least my land cruiser frens localy

I have carbureted engines out here in super hot AZ. Sometimes it IS a carb problem when this happens. Especially with ethanol fuel. It literally boils off in the bowl of the carb. I have non ethanol fuel available where I live and it does MUCH better. It still runs on the ethanol fuel, I have to prime the fuel bowl after it sits though.

You MIGHT have an ignition problem so the next time it won't start, verify you have spark. My old carbureted truck (not Toyota) used to die when I got a block away and restart after cooling off for 10-15 minutes. It was my ignition coil.

I was going to mention making sure your gas cap wasn't plugged up or the wrong type but it sounds like you replaced it. If your cap doesn't allow air in the tank as your engine uses fuel, it can starve for fuel at the carb.

If you verify it does still have a good spark after it dies, start troubleshooting your fuel system from tank to carb. The screen on the fuel pickup could be plugged up, plugged fuel or vent lines, failing pump or dirty carb that can use a rebuild.

Get a manual or see if there's one available to download. Good luck with it!
