Caboobaroo Posted June 20, 2004 Share Posted June 20, 2004 Well my Brat that I recently got had a bad disty so I dropped my EA81 2wd electronic disty into it and I also tore my carb down, let it soak in Chem-Tool, cleaned it up with some carb cleaner and put some new gaskets in it. Now here's my problem: it runs a little rich and when you're into it hard and then let off of it, it backfires sometimes. It also doesn't like to start very easily but my idle is where it should be. Is this a carb problem or does it sound like my timing is off or something? Just need some help:D Quote Link to comment Share on other sites More sharing options...
GLCraig Posted June 20, 2004 Share Posted June 20, 2004 Did you make sure the float was set right when you put everything back together Quote Link to comment Share on other sites More sharing options...
Caboobaroo Posted June 21, 2004 Author Share Posted June 21, 2004 yup I did. It was one of the first things I checked while putting it back together. I still can't figure it out. Now it has a problem idling while cold like the choke isn't working. Meh, it stil will leave 20 feet of rubber from the back tire pretty easily:D Quote Link to comment Share on other sites More sharing options...
wagonpowaa Posted February 7, 2005 Share Posted February 7, 2005 holy crap - everything is the same with my gen 1 brat. Are you running the Weber? I think it might be because of the cold, but its pissing me off. I'm only getting 20mpg too! Argg. Quote Link to comment Share on other sites More sharing options...
Caboobaroo Posted February 7, 2005 Author Share Posted February 7, 2005 wow is THIS an old post lol... I had the stock Hitachi on it and it worked but I was getting 30mpg out of it... I did drop a JDM high compression EA71 into my Brat and put a Holley 5200 on it (a Weber knock-off made by Weber) and it wouldn't run quite right for some reason. I had a lot more power though which was the upside but I was also getting like 15mpg from it afterwards. The electronic disty helped a lot IMO. If you need help with an installation, I did a write-up in the USRM here: http://www.ultimatesubaru.org/forum/article.php?a=38 If you need any other help, I have a revised FSM for gen 1 stage 2 cars that was revised in 1982 I think and I can do a step-by-step process of carb rebuild procedure if you'd like.

wagonpowaa Posted February 7, 2005 Share Posted February 7, 2005 I just had my engine rebuilt and I had my carb rebuilt too. Do you think it might be the jetting? When I had my stock hitatchi and my engine that was about to blow up I was getting 25mpg. Any other ideas on what it could be? Quote Link to comment Share on other sites More sharing options...
Caboobaroo Posted February 8, 2005 Author Share Posted February 8, 2005 so are you currently running the Weber or the stock Hitachi? If you're running the Weber, I'd look into getting it rejetted since its probably jetted too big. Quote Link to comment Share on other sites More sharing options...
