    VP 4.3GS Carb Tuning Vacuum Port?

    Yes. When I pulled the carb apart there were a number of cracks in the metering block, many that went all the way through. I got a new one from Holley and thoroughly cleaned the mating areas. All new gaskets on everything that had a gasket. I am pretty particular about cleaning. I spent quite a...

    VP 4.3GS Carb Tuning Vacuum Port?

    This is the 4160. Holley Carb R75007-1 I had not heard about transfer slots, and now I am not sure what I need to do to verify them. Do you know what they should be set to? The videos I am seeing is around .020". Do both the primary and secondary get set the same? Floats are not externally...

    VP 4.3GS Timing Help

    Volvo Penta EST I am getting ready to time my engine and there is only a notch on the timing chain cover and a notch on the harmonic balancer. If they are lined up is that set to 1 degree BDTC? There are no numbers anywhere else, no other markings. I have the shunt needed, just not sure what...

    VP 4.3GS Carb Tuning Vacuum Port?

    This carb does have a power valve. It was just replaced when I rebuilt the carb a couple days ago.

    VP 4.3GS Carb Tuning Vacuum Port?

    The only plug on the intake is in front of the carb, port side. Has a square hole in it like you could put a ratchet in it, but you can't. Wrong size. I am foulin plugs, it doesn't idle, and it bogs at WOT. I just put a carb kit in it. 4bbl Holley. I'm not sure the timing is right. I will...

    VP 4.3GS Carb Tuning Vacuum Port?

    I just don't see any other options on this engine. There are no vacuum ports on the carb or on the manifold.

    VP 4.3GS Carb Tuning Vacuum Port?

    So, put a tee in that hose and use that as my vacuum source?

    VP 4.3GS Carb Tuning Vacuum Port?

    There is a brass plug on the port side, front of the intake manifold, but I think that is a cooling system drain plug. Is that right? If not, I could use that. It has a square hole in it, too small for a 3/8" drive, too big for a 1/4" drive.

    I don't think I have that port. Holley 4160 with electric choke.

    VP 4.3GS Carb Tuning Vacuum Port?

    I am troubleshooting a rich condition. Bad enough that it won't idle well, and fouls plugs. I just rebuilt the carb and want to tune it, but I do not know how to hook up the vacuum gauge to get vacuum. This engine only has a large port under the carb that goes to the PCV valve. I will be timing...

    VP 4.3GS Fuel Delivery Problem?

    Metering block number is 34R11954A. I can't find anywhere on the internet that has that part number. Carb is R75007-1. I will have to call Holley and Mike's.

    VP 4.3GS Fuel Delivery Problem?

    I've got it partially pulled apart. The metering block is cracked. Looks like some one hit the center of it with a hammer. It's spider webbed out from around the center of it. That should be fun to find a new one. The front float was way too low. I'm surprised any fuel could get into the bowl.

    VP 4.3GS Fuel Delivery Problem?

    Would you buy the Holley kit or the NOS OEM Volvo kit? Volvo says it is unavailable, but there are a few folks on eBay with them still.

    VP 4.3GS Fuel Delivery Problem?

    That looks like the one I need. All the auto parts stores have the high pressure gauges.

    Just bought boat, most gauges inoperable

    Update. The tach is still wonky. It doesn't follow the engine roms all the way to wide open, it seems sluggish. The trim sender is bad, the gauge is good. The speedometer pitot is broke off at the nipple for the tube connection. The oil pressure gauge started working its own. Volt meter looks...

    VP 4.3GS Fuel Delivery Problem?

    The gas is still pretty dark yellow. I will drain the tank and clean it out. The gauge was for a fuel injected engine I'm pretty sure, it went up to 100+psi in 2psi increments. I put the filter on dry, didn't prefill it like you would an oil filter. The fuel line from the carb back to the pump...

    VP 4.3GS Fuel Delivery Problem?

    2000 Reinell 200C, Volvo Penta 4.3GS. I have been chasing a rough idle and bog at wide open for a few days. I was having intermittent problems with it cranking but no start. Now I can get it to start regularly. I rented a fuel pressure gauge set and hooked it up inline between the fuel pump...

    Just bought boat, most gauges inoperable

    I just bought a 2000 Reinell 200C, with the Volvo Penta 4.3, 4bbl. I listened to it run in the guys shop and it ran pretty good for just being started for the 1st time in 2 years. When I took it out on the water I noticed that I don't have an accurate tach, it only goes to about 2500rpms, no...
