the solenoid is 160 USD and the Sprocket is 280 USD and its a better fix than anything else… cleaning the original cam gear is much harder because it is too intricate inside and you will really never get it fully clean. i have 2 spare solenoids i can ship you but it would be easier to buy new… that is your best bet i think dude
