just before I found the hole in my engine head water jacket, I contacted Moyer.  He suggested that the last bolt in the manifold could have rusted away and...
I use Marvel Mystery Oil and my A4 will smoke when its first started, then goes away when it warms up about 10 - 15 minutes. ... No virus found in this...
Purchased this boat and engine sounds good with 90 compression. I have always had out boards and clueless on inboards. Intend to transport it 80 miles. What...
Common plugs are RJ8C or RJ12C, with a 13/16" hex. I'd look inside the distributor - check the condition of the points and cap. The condition of the fuel may...
I'd verify that the impeller for the water pump is in good condition, that the engine doesn't overheat under sustained usage, that the engine is in tune,...
I assure the group that I'm not sending blank responses; below is the information I sent. The list server apparently accepts my reply, discards all but the...
You might also consider replacing the coil. My engine would run great for one hour and then quit and would not restart. I thought it was bad fuel-(crud/water)...
I had the same experience, same symptoms, same wrong conclusion before installing a new coil. Don't need to replace the one you have: just carry a spare. Napa...
Hi Dave, Sorry, that was poorly written. I meant initially the same wrong conclusion as you: I also thought it was a gas problem. I added filters, cleaned the...
Marty; Thanks for clarifying that. I was afraid that perhaps I was not done with that problem after all! Yes, you really come to appreciate the engine after...
I too have had the same experience. In my case it turned out to be the low oil pressure safety switch. It has one moving part, and doesn't fail very often. BTW...
I'm advocating the installation of a bypass switch on the OP switch for priming the carb if nothing else. But, this switch is to prevent the pumping of gas...
Here's my current issue. My atomic four runs great in forward, no smoke, idle's easy, can even move the boat easily in idle while approaching dock. The A4 has...
The engine restarted right away because there is a wire from the starter that activates the electric fuel pump when the starter is working even with zero oil...
By jumping the electric fuel pump I have also been able to recharge the Racor Filter. the pump. the lines and the carburetor itself in a few minutes, after...
MessageDick; I had sticky float problems until I added MMO to the fuel. E-10 notwithstanding, I haven't had a float stick since. Coincidence, or....? Cheers; ...
Good question. Mine only stuck over the winter when theoretically the gas had partially evaporated and the valve should have been open. Don thought there might...
I'm in the process of upgrading my A4 and I currently have a diverter valve instead of a thermostat. It's a real pain having to adjust the valve depending on...
I assume you have a later model engine , The diverter is there because the bypass hose was designed too large and too much water bypasses with the original...
I have used the Moyer kit with the volvo thermostat for four years and it has zero attention. It was a very easy installation. Just my 2 cents worth. Allan...
I just finished pulling mine yesterday. I took it out in pieces, as I had to break it down for rebuild anyway. The topping lift (non-stretch Sta-Set)...
My guess is that something is wrong w/ the thrust bearing assemble. It'll straighten itself out when you replace the seal and bearing. Did you have a lot of...
Remember that w/ raw (salt) water cooling you want it to run cooler than 160. Dick Usen ... From: atomic4@yahoogroups.com [mailto:atomic4@yahoogroups.com] On...
Yes, it was a struggle with a puller and a breaker bar to get it off...I haven't broken it down further, yet. I left it until I had Moyer's manual to...
... Yes, I usually keep it below 160 to avoid salt deposits. I also flush the engine with fresh water at the end of the day. The PO had a bypass put in for the...
The rear seal area is a problem on marine engines due to the splashing from the stuffing box. I recommend a PSS seal for that reason, but baring that, a rubber...
