Petersubaru Posted December 10, 2005 Share Posted December 10, 2005 has anyone ever explained as to why the Hitachi carbs stumble or hesitate...perhaps I missed the answer when trying to use the search...anyway, I have had my 86 wagon since near new and with only 25,000miles on it at that time, it was already showing signs of hesitation then and has only gotten worse with time...I would like to do something to correct the problem(if this is possible) while at the same time keep the car original ....any feedback would appreciated Quote Link to comment Share on other sites More sharing options...
Cougar Posted December 10, 2005 Share Posted December 10, 2005 Have you checked for a intake manifold leak as a cause of this problem? Quote Link to comment Share on other sites More sharing options...
Petersubaru Posted December 10, 2005 Author Share Posted December 10, 2005 yes, I have checked and changed gaskets and rechecked spraying starter fluid Have you checked for a intake manifold leak as a cause of this problem? Quote Link to comment Share on other sites More sharing options...
Subarian Posted December 10, 2005 Share Posted December 10, 2005 Stumbling or hesitation (we're talking about acceleration here) is usually caused by a bad accelerator pump. If you get a rebuild kit it should take care of it. Quote Link to comment Share on other sites More sharing options...
hatchsub Posted December 10, 2005 Share Posted December 10, 2005 Yeah every subaru carb whether it be the hitachi two barrel or the carter-weber one barrel hessitated for me. I have a roo-builders hitachi waiting to go on my car and hopfully they have solved this annoying tendency. Quote Link to comment Share on other sites More sharing options...
