Re: 295 valves
The rocker arms in the older model were too soft. They upgraded them in the MCI engine. The new rocker arms work in all the older Robin engines.
The cam cuts grooves in the old rockers, changing the valve adjustment.
I wrote a thread re: rocker arm upgrade. See if I can't find some pics.......
I just brought up the whole thread... It's easier. Good Luck.
