Switching to Bike Carbs. Heres a write up!

[oldschool eighty8]

thanks guys.
I removed the intank pump, and the main pump was also taken out, I re-routed lines for a more straght shot to the front of the car. I think most of the problem was the front end on jack stands and my battery is a tad weak. Once I dopped the car back on the floor I was getting a steady 3.5 lbs with a lot less pump noise. I think once the battery is fully charged it will be fine.

Once you get it pulling it should siphon out of the tank and down to the line and feed itself pretty well, really.

Do those bronce thingies look right for obtaining vacuum? Or will it go ka-boom?

[ncbrock]

yep those are for vacuum! smart place to take advantage of the injector holes Plus thats a sexy looking setup

[oldschool eighty8]

Anyone have any ideas as to why I can't get my motor to pull fuel in on it's own? Running r1 carbs and a Carter 4070, I have the pump ground to the block and getting 12v I have it wired in by it self to a on/off switch. Fpr is showing a steady 4psi, but the only way I can get it running is to dump fuel into the carbs and once that burns off it quits.

Have you given the idle mixture screws the mandatory 3 and a half turns out?

That's from a dude in Guatemala, whom I'm helping, I had the doubt if those were good places to get vacuum from.

No I haven't touched them, this set of carbs was just recently used on a different car, I left them the way he had them.

have you primed the system for a while? at my first start up, it took me about 5-10 minutes to get it to start. once the fuel bowls filled up, the car had no problems. also, take the fuel line off the carbs and see how much fuel are you actually getting, dont rely on the fuel pressure regulator as of yet.

[oldschool eighty8]

I have had the pump running for a few min to check for leaks when I first installed it but I never really primed it. I'll give that a shot, thanks

I meant prime the carbs.

[oldschool eighty8]

I knew what you meant. I think I'm going to try a new battery. Watching the fuel pressure gauge out in the bay it drops to almost 0 when the motor is turning over.

Get a battery tender

[MKIGTITDI]

Sorry to post this here again but I've got a complete set up with a carter @4070 pump and Holley fpr carbs and manifold for a 8v cross flow complete for 400. Text me at 5412232852. I'm on the road a lot so bare with me if your interested based on where I'm at in regards to me getting it shipped off. I posted a lot earlier in this forum as both a counter flow builder and cross flow.

I have one, I let it slow charge over night before atempting to start it. Either the starter is on its way out or I need a battery with higher CCA.

i run a motorcycle battery with 310cca, no problems.

[oldschool eighty8]

Yeah but what's your compression? I'm running 12:1, it turns over hard.

[rysskii3]

no idea what it is. my head has been decked so i get about 225-235 psi per cylinder. it will crank over harder with carbs and it will take longer to start the car.

whats everyone doing for crankcase venting? got my carbed aba running, but blew the rear main seal. was thinking due to crankcase being blocked off?...what would be a good way to route cankcase back into the engine. not really wanting to fab a catch can...

Right now I just have a heater hose connected to mine that dumps under the car.
You dont have to fab one, you can get a fairly cheep one from summit or jegs

Got a catch can on mine.

Got a catch can on mine.

You guys got pics? I also am running a catch can but it seems like there is a lot of crankcase pressure still.

check out my build thread in the sig,
i have a dual breather setup, one for the block and one for the valve cover all connected to the same catch can.

[ncbrock]

You should try and do the old school crank vent through the exhaust. That's what I should have done in the first place

Yes, I had to force fuel through them a few times, now it starts with just a key turn.
