Haha. Wow. That is amazing haha.

Wow. So I figured it out. There was a silly one way check valve going into "selenoid valve 1" that was backwards. So happy/mad right now. Anyways, good info for future engine swappers!

course it does, you gotta warn people when the shark is hungry. Although now there are two huge hella 7" lights up there

Heck ya I did the graphics. My buddy and I sprayed em on after a few brewskies. I live in . . . . POST FALLS idaho! Where are you? To think there is another brat within 15 minuets of me. sigh. . . how beautiful. Thanks for the comments!

Hey guys, Im new to the forum and thought I would introduce myself and show you some photos of my 81 Brat! I live in Idaho and own all kinds of subarus - because they rule and make other cars whimper like tiny little diaper babies. I have a 81 brat, a 92 legacy turbo and a 2006 baja turbo. Here are some photos of me rallying "Sharkie". Lemme know what you guys think of ol SHARKIE! I bought it for 700 bucks with 135,000 miles on it. welp. . . .cya later.

That could totally be it! Although I don't really know what a secondary plate diaphragm is - However, the vacuum lines Im just sorta plugging in all willy nilly, according to my manual. The problem is the manual only has like 1/2 of the lines in it. Good ol chilton. My friend who is much more knowledgeable about carbs is going to help me soon and i'll make sure to run that by him. Thanks for the reply!

P.S. One important detail I forgot to mention was - I had the old carb on it, and it did the EXACT same thing, which lead me to believe it was the carb b/c the old carb was pretty much obliterated and covered in gunk. But the new carb still redlines it which leads me to look somewhere else than the carb. . .

Thanks for the reply. I am going to test the floats today. The distributor could totally be goofed up, could I disconnect the vacuum tube going to the vacuum advance to test if there are broken springs? Or do I just need to take it apart to look inside and see?

The throttle cable has slack in it. It was the first thing I thought of. I messed with the idle screw/fuel air screw/throttle stop screw and none of them make a slight difference. But i'll try them in the steps you said. I think I just need to put a piece of cardboard on the intake so that its not redlining why I am making adjustments, don't wanna blow my new engine. Im wondering if it is a stuck needle or vacuum hose somehow pulling in to much fuel. Thanks for the reply!

Hey everyone! This is my first post even though I read a lot of info on this forum. Anyways, I just finished swapping a 1986 or 1987 engine into my 1981 4wd brat and got it running successful. The problem is it runs to good. It acts as if it's always being floored. I even got a fcproducts remanufactured carb on it. I have tried everything in my feable knowledge like adjusting the idle screw, holding my hand on the intake to see if it's getting air from somewhere else, adjusting the fast idle screw, unplugging vacuum lines, holding the valves closed and timing (althought it's hard when the engine won't idle). It seems like once it gets warm the problem is less but I doubt that has much to do with it. Really, I'm not even sure it's the carb that is causing it and don't know what else to try! Any help would be greatly appreciated.
