Hello everyone,
Hopefullly I didn't miss a post about this on here allready. I did do several searches and didn't seem to find anything that quite matched my situation.
Thank you in advance for any help you can provide!
I am rebuilding the motor on my Chrysler Conqueror Shallow Vee and have been informed by my brother that the carbs may be shot.
The motor is a 1971 120HP Chrysler outboard.
As I understand it the engine wasn't running well and they were troubleshooting the issue. When one of them covered the ends of the throttle shaft with their hand the engine ran better and continued to run fine for a short time before the engine burned up the number 2 piston assumably from running lean.
From what I have been told the throttle shaft is worn out and can not be repaired.
Many years ago I used to rebuild carbs all of the time and have probably rebuilt a hundred or so carbs. Mostly on cars although I did do some heavy equipment ones as well. The only carbs I had ever seen a worn out throttle shaft on were quadrajets due to the teflon wearing off and the roughness of the cast surface wearing out the throttle plate and these were repairable with a brass bushing kit that consisted of a drilling an over sized hole and inserting a bushing.
So to get to the point here is this a common problem with the Tillotson carbs or is it likely that my brother is mistaken?
If it is a common problem are there aftermarket carbs that will work? Or is it possible to install bushings to resolve the issue?
Again any help would be greatly appreciated.
Thanks again
