madkow007 Posted February 6, 2006 Share Posted February 6, 2006 hmmm...25 mpg sounds about average for a 5 speed will get less with an auto (3 speed) Quote Link to comment Share on other sites More sharing options...
85Sub4WD Posted February 6, 2006 Share Posted February 6, 2006 15mpg is WAYYY too low for any tranny - ususally there is no more than 3-4 mpg difference between auto and manual - I would recommend that you check to see that the Weber is jetted right for your car, that would cause it to run richly - also if the choke is sticking, or the timing is wayy off - I have a good friend that got ~24-28mpg in town on his '84 with the D/R 4-speed 4WD tranny (better mpg on highway) - it also had a weber carb if you are running so rich you are getting 15mpg, you are actually losing power and a lot of it; peak hp output is obtained by a correct mixture (~14.7:1 air:fuel), not by putting in a ton of gas - you should notice a power, and fuel economy increase with proper adjustment just out of curiousity, what disty did you use, and what did you set the engine timing to?

GeneralDisorder Posted February 6, 2006 Share Posted February 6, 2006 I get 25 - 28 regularly with a Weber on my EA81 (stock height, 85 Brat). 15 is much to low. I would run a compression check, and read your plugs to get an idea if you are running rich or what's going on. Also make sure you have NO exhaust leaks - that will hit your mileage a bit as well.

1bignose Posted February 6, 2006 Author Share Posted February 6, 2006 the jets in the weber are right ones. iv leaned it out so its not runing rich it dose not smoke and has power. i just checked my compertion and i had 175 psi give or take i put a ea82 y pipe on it and then its a strat pipe rest of the back could that be part of it, also i dont have any DEQ crap on it so no egr vavle and stuff like that Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted February 6, 2006 Share Posted February 6, 2006 Ok - lets start from the beginning - what math are you using to calculate our mileage? Better yet - how many miles do you get on a tank? GD Quote Link to comment Share on other sites More sharing options...
1bignose Posted February 6, 2006 Author Share Posted February 6, 2006 at the pump i put about 12gal of gas i get anywhere from 180 to 200 miles on that tank i started to 92 octan in got more power but the same mpg Quote Link to comment Share on other sites More sharing options...
