Went for a drive in the 22 Australian tourer today and the car didn't perform well, it didn't climb the hill as it should. It ha a rebuilt engine with Shuermike counterbalanced crank, aluminium pistons with new rings in re-sleeved bores and everything else done (other than a new cam)
The engine mis-fires when at higher revs. Timer is a new Anderson and coils recent Patterson un-adjusted.
The coil box is rebuilt and the engine loom is new. Plugs are new and in good condition and a compression test yeilds goor resulys (except for No.4 where the tester won't fit.
So, I wondered, what else could the problem be, What else was not Henry standard?
I removed the compression whistle from No. 2 cylinder and found that the motor ran much better.
Can't wait till tomorrow to test run the car to see if that was the problem!!
I always wondered if those spark plug whistles affected performance.
Please let us know.
Is it getting enough fuel at high rpms?
Make sure there are no bolts, timer control rod or anything that might be shorting out the timer. Check it in the advance position. There is a bolt that comes up from the bottom of the pan that gets real close to one of the timer contacts. Maybe put that bolt in pointing down.
: ^ )
You failed to mention if your are running the engine on battery or magneto? If a battery is it 6 or 12 volts?

Tonight, in a darkened garage, start & run thru idle & speed ( with e-brake engaged ) & different spark advance/retard settings & observe for errant sparks to ground anywhere near the coil box, wires or plugs.
Is the timer clean & in good condition ?
He said the timer was new Anderson. Read the first post.
What brand spark plugs? Some of the modern types don't work well with stock ignition system, particularly if they are used with a thread reducer adapter.
A dirty Anderson will give trouble.
