I plan on turning up the governor on my GCV160 to ~3500 after I get a new blade, and I have a few questions regarding the GCV160 engine...
1a. Can the GCV190 carb be installed in place of the GCV160 carb?
1b. If yes, can one retain the Auto Choke System?
2. Can the GCV190 cam wheel be installed in place of the GCV160 cam wheel?
From what I can tell, the GCV160 and the GCV190 both use the same timing belt, valves, and rockers... but the cam wheels are different. I am hoping the GCV190 cam is larger [either in duration or lift, or both] , but still is a direct fit in place of the GCV160's cam wheel. There is a PDF on how to adjust the valves, so I am too worried about that part of it.
As mentioned earlier, I am going to turn the governor up... can one advance/retard the cam wheel? The cam wheel and timing belt both have teeth.
