Wanted Buzz Box

[Albert]

I had turned off the hose and only ran it for a few seconds.
Probably stumbling as it was starving for air with the throttle fully closed.
I didn’t dare rev it up as the kiddos we’re already in bed.

Quick video for posterity....

[Albert]

The basket case 80 lives again!
I’ll see about some video later for now it’s just great to hear it run.
Time to start work on the new one.


Pete,
You were on in your description, when fed from the brass plug the motor fills to the point where it flows...

[Albert]

I’ll try and answer your questions.
I wanted to feed water through the outlet because I didn’t have the proper fitting to go through where the brass plug is.
It was concerning because I assumed water only exited the motor through the hose from the exhaust manifold. So when...

[Albert]

Take two....

[Albert]

Alright Yamato 80 gurus riddle me this. Why is is when I feed low pressure water back through the motor it’s flowing out this port on the bottom of the cylinders instead of out of the regular coolant passage that leads down to the pickup?
Is this a pressure release that operates backwards...

[Albert]

Belay this want ad, found if I take the wires off the points it works fine. May have a bad ground somewhere leading to issues....

[Albert]

Pete,
Sorry for the confusion. I meant I have used the same unit you have with good results.
I was trying to use a Central tool company 273 which is also supposed to be a good unit (if a little old).

[Albert]

Pete,
I have used that exact unit, and it did work well. Likely what I will get for myself but was hoping to make this one work that we have.
Or get a good used unit from someone who has made the move to a cdi motor.

[Albert]

I know this isn't the tech forum, but I'll ask. Right now regardless of if the points are open or closed the buzz box is buzzing. Also tried a second motor with the same result. I have tried moving the other clip from to different locations with the same result. It's as thought the points are continually...

[Albert]

I have reason to believe that the buzz box my brother acquired and I intended on using on all 3 of our motors is not functional.
Anybody have a good used spare unit they want to part with before I send my money to speedway?...

[Albert]

Matt,
Welcome to the site. I've stood next to a popper helping them launch and the noise is really something. That being said if your neighbours are understanding and you're only going out a few times a summer...It would be a shame to leave those parts on the shelf....

[Albert]

Well I put a couple inches of water in the boat today and found exactly 0 leaks.
I’m no mr Holmes....

[Albert]

Permatex motoseal for the crank case sealant.

[Albert]

At the base gasket nothing but the gasket.
At where the powerhead meets the tower just the gasket...was going to run a little sealant around the exhaust but the gasket removed showed no sign of leaking. (I know double standard compared to the hg sealant )

At the foot, I plan to...

[Albert]

A good cleaning and this thing might finally be nice enough to earn its keep on the back of the Bezoat!...

[Albert]

No issues with head gaskets on this motor so far. I guess it’s a habit I just picked up when doing my first turbo diesels with 24:1 compression ratio and an extra 25psi of atmosphere being shoved in the cylinders the head gaskets on them needed all the help they could get.
As I said I’ve...

[Albert]

It’s an oe .5mm, I sprayed it with permatex copper hg spray. I do it to every metal head gasket I install. Two coats and let it tack up then install.

[Albert]

Now we’re getting somewhere.


Edit: It has been suggested I get copper washers and fresh hardware for the head. I think that’s a good idea will order on Monday....

[Albert]

I think the seal retainer was knocked loose when I was trying to removed the seized foot last year. It required quite a lot of persuasion.
Either way it’s in now and I just pressed a fresh seal in before the baby had time to wake up from her nap.
Also took a few minutes to shape the...
