Listeroid Engines / Re: Ashwamegh 25/2 :the saga continues
« on: October 26, 2018, 09:07:52 PM »I just can't get this thing to produce power.
I sent the cam to Butch who installed the new weights and see no change.
The engine will pull about 1600 watts but if I load it with another 1000 watts it just won't
do the deed.
With no load I set the speed to 720 engine rpms. That will give me 1800 at the gen head.
I see 120 volts at 63 HZ. With a 1600 load it does 117 volts @60 HZ.
But another 1000 watts and the voltage will fall to 93 volts @ 54 HZ.
The engine is not "working" at this speed the governor just won't "pick up".
I tried several springs and spring combinations.
I am thinking a larger gen pulley to bring the engine rpms up to about 800 or so.
The engine has always run very close EGT's but I see a slight difference now. I guess this is do
to the new cam lobe on the #1 cylinder. I haven't reset the timing on that side yet but I don't believe
it is enough to cause the problem I am having.
I am open to ideas.

Hi Garry,
It sounds like a too short or weak governor spring, as you know, the spring pulls the rack open until the revs come up and the gov weights throw outward and pull the rack back to the set speed, it has to be the spring.
