I love the 1966 tech! If it breaks down on me 12 miles offshore with the kids and wife I have a good chance at fixing whatever is wrong with simple tools and no computer needed. I’m not a Luddite, I have a 2023 M2 MacBook Pro, tech where it makes sense. Displacement where it doesn’t :)
I want...
Update- Thanks again for all the ideas here folks. I swapped the carburetors from engine to engine and did a sea trial. Still only hitting 3500RPM. So, not the carbs.
No anti-siphon valve inline either- 2.5’ up from tank to fuel filter housing. Will be replacing those lines, they are worn...
Ok, no anti siphon- the engines and fuel system are about 2.5 feet above the tank. It’s just hose from the an elbow at the tank to the fuel filter, then pump and short braided line. Glad yours is running good!! :)
Good call on the choke, it’s been problematic on my old carbs. I’m just going to disconnect it, we don’t need choke here in Florida but maybe 1 day a year. :cool:
There are individual lines from tank to engine, but I don’t think there is anything in-line between the out from tank and in to...
Hey Lou, thanks for your comment. I've got two engines on the boat, the Port engine is working fine and they're pulling fuel from same tank. It does make me wonder about the carburetor though- I think I should swap the carbs and see if the issue jumps to the other engine.
I have not checked...
This is great insight, thank you! The ignition coil I bought is the specific Volvo part # - the distributor I ordered is this one from A-Team, should I cancel that and send it back?
Which distributor did you go with that worked for you...
Also, it's the STBD engine- here's what has been done chasing this gremlin:
I installed a new carb on my starboard engine it won't make full power under load. Once the other engine helps pull it up on plane it will go to ~ 4800RPM @ WOT, the throttle linkage opens all the way (I've had other...
Hey everyone, thanks for the welcome and comments so far. Here is a better video of it. -Brand new Holley 2BBL installed, new fuel pump, new filters.. are there two fuel pumps on these?
Anyone that can figure out why this engine is doing this (not accelerating past 3500RPM and surging / dropping RPM at top end) wins the title of Google Dr Diagnosis for the day- thanks in advance!
Jumping in late here- Volvo Penta ‘99 GL, carbureted, I have NGK5599 plugs ready to install but there’s some conflicting info on GAP- I see .49 and .61 out there, who has a definitive answer on it? Thank you!
