Will today I pulled the carb off and cleaned it up. It was a bit oily from the oil mist. I added the 1” spacer to help with the heat and it has a vacuum port if I need to add a PCV valve. Attached is a video I took with a paper towel over the oil fill. As you can see there isn’t much blow by...

The carb is a new Edelbrock 1409. The motor has about a 100 hours on it. The oily mist is making the carb dirty, that’s why I added a catch can. The motor runs great! Thanks

I’m adding a 1” spacer under my carburetor with a vacuum port. The port will be capped off for now. I have installed a catch can to capture the oil mist to keep the carb clean. Should I add a pcv valve to this setup? Is there any benefit to have a pcv valve? Every once in a while I get a...

Today I went out crabbing for 3 hours. No oil burn from yesterday and today. I’m going to install a catch can system to each valve cover vent tomorrow. The inside of the carb and vent hose are a little oily from the valve cover vents when running the motor hard. I usually cruise at 3000-3500...

I’m having a weird problem with my oil. I can run the boat 3 days in a row and the oil on the dipstick stays the same. When I have it pulled out and it sits for five days or more the dip stick reads low at the add mark when back in the water. I’m using Volvo 25-45 non synthetic. Any ideas after...

I didn’t change anything on the edelbrock 1409. I just adjusted the air mixture. So far so good.

Follow up after putting 30+ hours on the new setup. The 5.7 runs like a top with the new Edelbrock 1409 and Walbro fuel pump. I’m guessing my fuel burn is around 10 gallons an hour running at 3000-3100 rpm 26 mph. So far so good. Again a big thanks to all the helped out!

It’s been a fun project. The 1409 was easy to get it dialed in. Now on to redoing the dash and flush mounting the chart plotter and depth sounder. Thanks again 🍻

Just a quick update. I got everything dialed in today. The choke is working good now that it’s getting 12 volts. It’s running so much better than before. Converting from TBI to the edelbrock 1409 is the best thing I could have done for this engine. No more chasing gremlins from the old...

Thanks Scott That’s what I was thinking. I added a 7 amp inline fuse and moved it to the ignition purple wire. I will check it out in the morning and see if the choke works better. Thanks again. Cheers!

I have another question I wired the purple/white wire to the top left post per wiring diagram. Checking voltage. This post only puts out 7 volts to the choke. Holly And Rochester carbs only need 7 volts for the electric choke. The edelbrock 1409 needs 12-14 volts. Can I add the purple/white wire...

Installed the new Walbro FRB 13-2 fuel pump today.(nice pump) Ended up resealing all the fitting threads with Gasoila thread seal. The pump was noisy getting it primed. Once prime, it was really quite compared to the Carter.( I think I got a bad Carter pump). Ran the new setup for a 1/2 hour in...

The outlets are outside of the area that is getting fuel in. The fittings aren’t leaking I double checked with a paper towel while the engine was idling. I pulled it and returned it. It was also really noisy. I had it mounted on 3/4” rubber spacers. I’m not taking any chance for a fuel leak. I...

Is there a better electric fuel pump than the Carter? I don’t like it that a brand new pump is leaking in my engine compartment. I have a replacement Carter pump coming. I may send it back and find a better pump.

Permatex gas proof sealer Is this the wrong stuff for thread sealer? The threads are not leaking It’s the pump. If there is something better, please let me know. Thanks

Ran the engine in the driveway to check everything out before taking the boat out for a sea trial. After running for ten minutes I could smell I very faint gas odor. I shut everything off. The fuel pump is barely leaking (red arrow) where the motor canister is pressed on the inlet housing. I...

Thanks I haven’t touch the timing yet. Both the TBI and carb are set to 8 deg TDC. I will sea trail it and see what it does under a load.

I didn’t use a bypass or blocking regulator. I’m using a Holley 12-803 set to 5lbs. Is this ok.

Thanks everyone for your help. I fired it up today. With a few adjustments to the carb at idle. Dialed in the fuel pressure to 5lbs. It runs great. The Carter fuel pump is loud. I will probably replace it with a better one in the spring. Not sure which pump is better for this application...

Thanks I will try that in the morning
