Ed......yes, because of your failure to a point.

Bruce........I have checked the upper shell several times during the 200
or so hours.

In my mind, because I did not do a break down when I got the engine,
I think it's more than a question of IF. It's more like WHEN.
I think I should at least do the best prep I can and no visual inspection
of every surface leaves a lot of room for "if only I had looked at that".
Now I wished I would have done it to begin with. But it needs a good
cleaning and paint job as well. The original paint is flakeing off everywhere.

I think.she smokes a little more that it should so it will give me a chance to
inspect.the cylinder as well.

I didn't get much done today other than soak, pressure wash and blow.dry.

Stay tuned !

My new 7.5 st head came from Tom with the AVR installed
and the voltage set at 220.
I want to set it for 120 volts.  Can I just move the "U" connections
and reset for 120 volts or do I have to change anything on the AVR ?

I hope this question makes sense,
Gary

I run my 25/2 the same. 1000 derated to about 725 or so.
No problems but I did spend time adjusting timing and linkages.

I thought this 9 year old thread amusing.
Remember Darren ??
How funny !


Gary

Oh, yea.....we gotta' see those !!!!

Gary

They want to run with a load.

Advise ? Read, read , read then read some more.
Good luck,.
Gary

I did a cleanup, sprayed well with the red "varnish", new bearing
and added wood and epoxy shims to the loose bobbin.

I get just a little imbalance growl when the load gets up to about
10 to 12 amps on one side.....man, I'm happy with that !

This unit came with the AVR and "modern" rectifier.  Whoa, almost
forgot the DIGITAL volt/frequency meter. What will those Indians
think of next ??

Just though you guys might like an update.

Carry on,
Gary

Thanks Gary.

I don't know if it will help but it's worth a try.
My other 7.5 and 15 kw heads are both quiet.
This sounds like the laminations are rattling.

I will get to it in the next few days and will post the results.

Gary

That is probably your best best......think I'd opt for a new shaft as well.
