Yeah I figured that out. However I don't understand the purpose of that.....
-
How come the second butterfly valve on my carb doesn't open?
-
I already did, its still doing it. I think its carbon build up... Saw a lot on my plugs. It really needs the rebuild. I was gonna use a mizumo rebuild kit. Any kits you guys recommend
-
My intake gasket was the leak needed replaced and now its running great thanx guys. However my engine still has a harsh turn off.
-
Yeah I cant find any other vacuum leaks then that one hose. I still hear whistle but i cant find anything I traced through all the vacuums. I really think I just need to rebuild my carb since the truck was sitting for so long. Are the servos for the heating vacuum controlled?
-
I planned on doing all fuel lines and brake lines asap. The truck was sitting a few months before my boss got it and I bought it from him. The truck will be taken down to the frame and fully restored. I can't let it sit though as its now my daily driver. Me and the gf was sharing a car and it was quite stressful. When on the highway or driving I have no issues. Only when returning back to idle goes it seem to have issues. Since I advanced the dizzy I accelerate a lot better and even the tires actually burn rubber it no longer bogs
-
I dont know how to check or adjust the float =/ Not too familar with tuning carbs Yeah every once in a while when I'm accelerating it feels weak and bogs. The fuel filter is in the tank right? Would it be a bad idea to put a inline filter on it in the future? I was hoping the sea foam would help flush everything out. I have a lot of condensation in my exhaust also. I dont think the genus who had it last had the weep hole on the bottom of the muff. Idk I have a foot and a half of spray from my exhaust every start up. I advanced my distributor a bit and its doing a lot better. Also no matter what way I turned my distributor the car would adjust the timing and tune itself for the most part.
-
Its a points dizzy, I went through all the vaccum lines yesterday had 1 split so I cut off the split part and put it back on. Not sure about the fuel as I just bought the truck last saturday And it was running rough then so first thing i did was put seafoam in the tank and filled her up. Also bought a can of carb cleaner and sprayed it out. Still no change, Just to get it to run I had to adjust the idle from the screw closed to the throttle cable then at the idle that was capped I turned it down to the point where it was going to cut off and then adjusted in up a lil. Yes as I couldnt tell this was happening until after I did the distributor cap wires plugs and rotor.
-
Yeah I'm a little intimidated by the blow thru :rofl: Mainly because of the carb I know the basic operation and how it works but idk never rebuilt one before lol. So I dont know what makes a carb better then the next is basically what I'm saying. I've always dealt with fuel injection so this is a bit of a flip for me. I've built small block 350's before but still never handled the carbs too much. I will do more research on the blow thru as its what i wanted to do in the first place but draw thru seemed like a cheaper and easier way out for the small amount of boost i was wanting to gain. I think I'm just gonna forge everything and go balls to the wall. Thanks for all the advice I'll be sure to message you if i have any questions.
-
So I've replaced my plugs and wires dizzy cap and rotor. Cap was melted on one terminal thought it was my issue but my rpms keep going up and down. I figured it had to be my carb as I had adjusted the throttle cable to be able to drive it. Also has an issue recovering back to idle after letting off the gas. Any suggestions?
-
Yeah I'd only be running 8psi as I'm only doing a stock rebuild on the engine. And I'm unsure how much this engine can handle on stock internals. And I see what you mean. I didn't think about pooling :/ I suppose if it ever misfired I'd have a bomb under my hood. Dam I thought I was on to something... My pockets aren't deep enough for a blow through setup hahaha. Would there be much back pressure to the turbo from the intake? These aren't exactly high rpm engines so I wanted to rid as many obstacles that may lag the turbo.
-
I read the post but its not the same as my setup. It goes carb---turbo---engine but I'm wanting to displace the pressure in a tank essentailly. Then feed a tube from the tank back between the carb and turbo. Carb---Turbo---Engine #####|#######| #####|######BoV ####IGR######| #####|________displacement tank
-
So I had an idea for a draw through turbo with a BoV. So rather then burst a bunch of atomized air/fuel under the hood of my truck. Why not setup like a egr so it would be a igr lol. So basically the Bov would release into a large diameter tube to displace some of the boost then back k around to the intake just before the turbo. Now my only question is will the bov work not having a throttle body to bounce off of. Or could I remove the carbs butterfly valves and use a throttle body at the intake?
-
Sorry didnt know the link would break if I uploaded more pics. I will find a dif place to host my pics. Well I'm setting up a draw through turbo system on my z24. I was going to do a blow through but for the amount of boost I was gonna run. (8psi) An intercooler wouldnt really do anything for me. And its a pain in the ass to tune a blow thru my only concerns are the initial startup with the draw through system. Having the carb so far away from the intake manifold. Should i be worried about that? I plan on making it as short of length to the inake as possible. But still sitting pretty under my hood :angel: My boss goes to the auctions and hes gonna snag what ever he can find with a weber on it to give it to me. Hes giving me what ever I want to help out with my build. Was just curious about the varajet as an alternative. Right now with the stock my throttle response just seems to suck. I may just rebuild it, currently the idle is all kinds of f'd up. When pressing the throttle and release it almost stalls but then somehow regains its idle and i think pieces are missing off it......
-
Think I should try and run it lol? I'm waiting for a weber to come through the salvage yard again.
