gadberry Posted December 20, 2017 Share Posted December 20, 2017 Hello everyone, My 1981 GL 4wd 1.8 wagon had sat for @ 8 months while I slowly found/fixed the electric cooling fans issues.... After a fresh battery charge I jump in to start it up and the gas pedal is 'Stuck' and won't budge! I check the accelerator cable and it's fine/free and try to rotate the 'throttle wheel' on the side of the stock Hitachi carburetor and it won't budge. Sprayed some liquid wrench around the throttle shaft but I'd guess that i may be seized within the carb body as it passes through to the butterfly/intake? Any ideas/thoughts? I've not had a chance to look since applying some of the liquid wrench (due to the weather and work) but I thought i'd ask everyone here... It feels like the throttle wheel is mechanically stuck and doesn't budge a bit! * The car had run hot the last time it ran because the cooling fans had a short, so that may have contributed to this issue, and I also remember the idle being HIGHER than normal as I moved it a few blocks to it's current resting space.. It's beginning so sound bad already... isn't it.. but hey, hopefully, it's just another crappy Hitachi Carb quirk.. (the ole sticky throttle shaft!!) I've searched the forum but haven't found anything like this, yet. thanks in advance!! gadberry Link to comment Share on other sites More sharing options...
DaveT Posted December 20, 2017 Share Posted December 20, 2017 Did you get the liquid wrench on the other end of the shaft also? Link to comment Share on other sites More sharing options...
Knucklehead Saloon Posted December 21, 2017 Share Posted December 21, 2017 Try some carb cleaner down the throat too. I had a similar issue with an old ford once. Was old fuel gum that had laquered the throttle shaft and butterflys along with a little corrosion on the shaft. Carb cleaner then lubed with a silicone spray.

GeneralDisorder Posted December 21, 2017 Share Posted December 21, 2017 Melted ASV "silencer" (muffler) got sucked into the carb and glued it shut when it cooled down and solidified. Will likely require a carb tear down. GD Link to comment Share on other sites More sharing options...
moosens Posted December 21, 2017 Share Posted December 21, 2017 Ahh , the story of Skip buying my Brat and going over the Appalachian mountains on the down hill side and the throttle stuck open. Same as above. Melted black plastic. Link to comment Share on other sites More sharing options...

gadberry Posted December 22, 2017 Author Share Posted December 22, 2017 UPDATE:. I checked to see if the Liquid wrench had worked, and the throttle mechanism was still stuck even though I could 'open' the butterfly valve by pushing UP on the "plunger device" on the outside; rear of the Hitachi Carb (sorry for not remembering what that's called at the moment).. So, I placed a 12mm socket over the end of the throttel shaft nut and slightly loosened it and then re-tightened it... and it's free and working again.. pedal feels normal too. Now, if I only had a good battery on-hand, I could try starting her up again... but the battery was "fully charged" last weekend and now only measures 11.9 volts. I'll check back in a few days after I've confirmed it's all back to normal. Thanks everyone for input and suggestions!! best to all and have a peaceful holiday season gadberry Link to comment Share on other sites More sharing options...
