Working a buddy's 1977 Tahiti, 460 Jet and found a marine distributor with points and condenser inside. Has two clips on the sides like the old Fords, but the rotor looks a little different. Wider at the end away from the contact. This is a Berkley Jet, and does not have a covered engine, water...
So the first pic is a connector by the front of the engine near the thermostat that I can't find a connector for, but it sure looks like it should be plugged into something. The second is a plug in the pink wire between the dizzy and ECU? I think I'm supposed to pull to check base timing and...
Scott, thanks for the education, I see there are differences between automotive and marine stuff. Maybe I should be working harder to find the idle issue on my EFI. I'm just at a bit of a loss as to where I go from here. I suppose pulling the lower intake and looking for possible air leaks is...
I didn't see this until now, Thank you so much! Still having issues with the idle. Was unable to find more vacuume leaks, but have the gaskets for the lower intake manifold. Was intending to swap out to an Edelbrock with a Holley, but if I find issues under the lower section maybe I'll see if I...
Replaced the IAC with new, no difference. Are you saying that corrosion will be an issue with aluminum? Or is that a salt/brine water issue? Not heat exchange cooled. A 351 C.I. engine at 6,000 RPM will displace 610 CFM at 100% efficiency, which nothing naturally aspirated will. Chevrolet ran a...
Opps, brain fart, yes it is a V/P. It is EFI at the moment, and runs perfectly except for not idling down like it should. I don't think there's a "top" for it to leak fuel from. Yes if it were Carbed and had the EFI pump it would surely leak fuel and flood. The EFI pump should have an electrical...
I am looking to swap out the fuel injection system on my 5.8 Mercruiser (Ford) for an aluminum manifold and a good old fashioned Holley 600. I just can't get it to idle down below 1100 RPM. My question (s) are where is the fuel pump located, assuming I'll need something with a lower pressure...
I'm working on a 1996 Four Winns 220 Horizon. It's got a floor panel creaking when it's walked on. I bought plywood, thinking it must be soft, (and a couple other projects) and after removing the panel I find the supports that go across the fuel tank are cracked. They cut a V notch in the bottom...
There is a stop screw that keeps the air valve from sticking closed, the valve closes well against the stop, but the idle is still erratic and around 1200 rpm. Even if I back it out, with the valve closed tight. Shifts easily in and out of gear out of the water, but very had to get out of gear...
Are you talking about under the Upper Manifold? Under the Throttle Body? I will get some brake cleaner, (easier on paint) and spray selectively around that area as well as the base of the upper intake. I'm familiar with the OBD II test ports on autos, but what do I need, and how do I connect to...
I have a 1996 220 Horizon that idles around 1200 rpm. Somewhat erratic and slow to return to idle after revving or running at speed. So far I've changed the IAC valve, the TPS adjusted the stop screw to just the point that the butterfly does not stick, and resealed the two throttle body gaskets...
Thanks for all the good advice and tips. Lou C, I once watched a short block on a test stand being spun with oil pressure to do a break in. At around 600 rpm all the pistons looked like they were all at the top of the cylinders. At 1000 rpm you could push straight down with your finger on top of...
