:confused: I am scratching my head on this one...a lot. I have a 1984 carburated GL wagon that surges occasionally. Starting and running cool is fine. When the engine temp reaches operating temperature it begins to surge like a lean surge, but after a little more driving the surge goes away. Once the rig is turned off and restarted when warm it surges again but goes away and runs fine after a little bit. I have changed the filters, tried a couple different carbs, checked all vacuum lines, adjusted and readjusted fuel mixture, and several other things. Plugs, wires, cap, rotor are all good. The fuel runs at the correct psi and this problem persists. Any suggestions?

Sounds like it might be the disty. Try a different one.

Throw a timing light on it and see if the timing is changing. i dont remeber if this has a vac advanced on it. If it does disconnect it. This will tel you with the timing light if the carb is doing something weird. or the dist is.

Thanks for the help guys. I am trying to get my hands on another dist but funding is tight. I really do appreciate the help. Will let you know what happens.

what kind of plug wires are you using? My loyale had some cheap wires on it and made it have a hesitation, then i replaced them with NGK wires and it went away.

 

subarus are just to damn picky when it comes to ignition parts.

I'm running the NGKs. Thing is it only does it when hot and only after I turn it off and restart it when hot. Also found that it is not running lean but that it is choking out from too much fuel.
