    Knock Sensor Faulty?

    I have the same ignition system, same year. Mine is mounted on the back of the motor, but no difference, if you think the timing is retarded based on symptoms, you need to verify with a timing light first. You can check the knock sensor with a scope, or you can have a buddy tap on the block...

    Bought a new long block and wondering about the coupling and gimbal bearing.

    Amazon lists it at 15 Amps, however it is made in China

    good point, I did bypass it at one time, which did not eliminate the problem, however the switch could heat up and interrupt B+, 1.2 AMPS isn't much, will find out the capacity of the switch.

    I did remove both connections and tightened up the female spade terminal, they are awful to get at. I should have made that more accessible. I still had issues when the pump was hot wired. There is not a relay on the fuel pump, the minimal info I got with the "pump kit" form Michigan Motorz did...

    It entered my mind, I blew through the line out of the tank and it passed air in that direction, however I guess its possible that its not continuously letting air in, something else to check.

    I used a Edlebrock 1" riser which seems to match Ok, although I did match the intake to the riser with a router as there was a lip at the intake an ED said that is not ideal. It was quite interesting, at start up slightly rich, once warm it typically is right at 14.6, it sure helps to set the...

    I decide to go through the fuel system, I remove all fuel lines one by one and blow through, capturing the fuel, I remove the filters and dump the fuel into a glass container. I remove the brass adaptor nut on the carb. I blow back through the line to the tank and vent is clear. I did not remove...

    I had a fuel problem pop up on this trip, I think it was of my own doing. When we put this boat together the motor/drive has a water separator/filter mounted on the block and hard plumbed to the fuel pump and carb. the boat came with a Racor with a drainable bowl. From my research some people...

    We made a trip last week, put on 476 miles, (fuel was $5.80 in Valdez EKK...!) I reset the choke, which was too tight, starts right up and no black smoke. Some pics of the carb and new engine.

    That mechanism is not on my carb, was not removed, was never there, everything regarding the choke is on the fuel inlet side.

    Actually the 750 is pretty common from what I have seen, it was the factory 4 bbl in 97. If one does the math on cfm requirements for a 350 a 600 cfm would be more than adequate. However my experience indicates there is no downside with the 750, it simply acts like a 2 bbl until the secondaries...
