A 351w (stroker?) from scratch...

Whatever it is that likes to knock again off again was on again after a day of hard running in Lake George with Reid, Critter, and Flyn Brian. We popped the breaker giving the little orange mustang a jump, and after idleing around around for about an hour being slightly aggressive with the volume on the sound system, the boat died and when we reset the breaker and jumped it back up it came back with a serious alternator squeak/stick and a less serious but there knock. The alt noise eventually went away after the battery charged it went back on the trailer with a little knock.

So out it comes, best case scenario actually as it made it though the season and then died. I would hate to have put it away for the year thinking it was fine then have problems in the spring. I have of course really wanted to pull it since the first failure which was the dist gear as I have had night mares of where those gear pieces ended up, then once I got into valves sticking the writing was on the wall but with it running good and quiet it was hard to justify. Now I have justification and you know while it's out...

I think I am going to leave it at I am going to put a fresh set of plugs in it, and see how she runs.

Lewy,
     Mine is a Marine carb and came that way from the factory, its very nice its not cheap but I would buy another. In fact I am buying another slightly larger one for this boat, and moving this one to my mustang. I doubt there is any performance difference if both are well tuned but the demons are quality units and look pretty good for a calibrated gas leak. If you do convert an auto version, expect it to look like crap pretty quick unless you keep it oiled up.

Yes there are.
It takes more than J-tubes to make a marine carb. Among others, The throttle shafts are -ringed so fuel doesn't leak out them if, er, when the float needle sticks open and floods the carb.
Also external float adjustment and sight plugs are a modern no-no.

Brian, what is the price shipped to the boat doctors shop. That is not what the Doc ordered but if the price is correct we may be able to deal..........Billy
Or better yet give me a call
      1-318-386-2825

Brian, Give me a call and we will work out the details, adress etc......Billy

Being able to get float height easily set was one of the features I really liked about Holley carbs.

I would say because the fuel can actually wick through the threads over time on that style carb.

So I am now finally into it...
found the culprit..
I went to the plumbing store to get components when maybe i should have went to the automotive store.



this cruddy fitting didnt take the weight of the two sending units and after pounding on the waves of lake george she broke and started leaking..



So a little cruddy adapter fails and the fall out is...

Looks alright here ...



but whats this...



a disgusting about of debris..

might be this ..




that black rod stick out like a sore thumb.. off to the machine shop we go...

It was out of oil, i am guessing the crank can be saved, will know for sure tomorrow when I pull it out..

Joe, that little rig job cost you big time.
As fanatical as you have been to dot every I and cross every T and you use brass for oil senders, 1/4 to 1/8 to support that much weight??????
We wont do that again will we!!!!!!!!!!

Joe sorry to see the pictures/news but hats off to you some would have not post the bad news, you will soon have it running again.

That's awful, and you had that engine running so well. Is that smaller sensor for the fuel pump or an alarm? Why didn't the alarm go off or fuel pump shut down?

Boat Dr, most of those rigs I've seen are made of brass. What else can you use?

Joe..wow, it looks like you went panning for gold!

chips got lodge in the passage way for the one journal starving it of oil, could have been any one, some might not have been as severlly blocked as the one that's why I would assume it's coming completely apart to clean all of the chips/junk out of the block.

I'm just wondering how many more lives this block has left in it before something punches thru it and turns it to junk.

the hyd. grade helps but I don't think you want to step it down a size like you did last time As that was the point Billy was trying to stress.


It just looks like too much junk in the pan to be all bearing's seems odd too for them to chunk like that, appears like oil passage ways where not cleaned out completetly or that's the dist gear but thought you cleaned it out after that, There's just an awfull lot of crap in the bottom of the pan and it's hard to beleive all was from the bearings.
