Loud squeal and no idle. Replaced head gasket, put engine back together now this…. :(

[philprendergast]

I replaced the head gasket. Put it all together and started it up and it’s whining and squealing. What’s the issue? Also, the carb won’t idle, I assume it’s got something blocking the jets or some kind of issue. So far this boat has been a huge hassle! Any help would be appreciated.

See video of how it sounds

I don't have a clue other than something is rubbing/slipping.. maybe the flywheel or a belt?

Took belt off and the sound remained

It sounds like the starter is staying engaged when the key is released.

That's a good possibility!

Not trying to insult you, but did you adjust the valves at TDC on each cylinder? Did you check ignition timing according to what ignition system you have?

 

[philprendergast]

Im an amateur! Nothing can insult me. I did adjust the valves as per the manual. I have no checked timing as I don’t have a timing light but may need to get one.

Willing to bet is a vacuum leak is throttle returning to closed position held closed by throttle cable

Great question: I dont think it is. I took the carb off the manifold when I did the head gasket. I put a new gasket under carb but I don’t think it’s seated right. Could the leak be coming from the base plate of the carb?

Check this video for more sounds and info. The throttle cable detached

Yes check that and the manifold to head gasket and bolts

alternator whine????

alternator whine????

No unfortunately. Took the belt off and it still made the noise

I guess your next move is to verify that the starter motor gear is not stuck..

Or Gimbal bearing needs More Grease? When was last time OD serviced and alignment checked?

Can you list all of the components you removed and reinstalled as part of this repair?

 

[QBhoy]

Hi. I’d check the water circulation pump on the engine, for an issue. If not the starter being the issue

Turns out it was a vacuum leak. I forgot to scrape off the old bits of gasket on the bottom of the carb . Runs awesome now. Time to get it in the water this weekend
