I just posted this YOUTUBE on a previous thread....and I did mention trying a Chinese carb just to eliminate the possibility of anything else contributing to the 'off idle problem' with sputtering, choking & stalling....I did take all the electronic steps such as timing, firing order, vacuum, & advance which all checked out to be positive....There's an overwhelming responses as to suggestions and I give them all credit and not dismissed any....I have learned that this carb issue is one of the most addressed topics, and it spreads to many various years & cubic inches of engines... Now I'm sure we can all agree a pre smog Chevy 6 cylinder is probably the most basic engine, so getting it to run correctly should not be a complicated mystery. My conclusion and beg to be proved wrong is that carburetors have wear patterns like everything else..most so subtle that cannot be seen. and corrections for wear are not included in rebuilding kits....Granted, bad gas, dirt, leaky floats, warped bodies, plugged passages, and then some, are all obvious issues that can be addressed, but once all these issues are addressed and the result is the same then what? Speaking for myself, I have had my carburetor off my engine several times and apart.... so much, I no longer need any reference to take it apart & put it together.... Its done in a clean environment, no distractions, no interruptions. The internal springs, and tiny balls are where there suppose to be, the accelerator pump is working fine, no play in any bushings. After everything is said & done, I cannot drive my truck out of my driveway..... By the way, I bought the truck with the seller disclosing a carburetor issue and running poorly....I found this youtube interesting... the engine compartment looked a little rough around the edges, and that carb base gasket blew me away....Dispite all the crudeness, I was impressed with his action of checking the richness with the vac gauge and his knowledge. It wasn't like he slapped on the carburetor and walked away...Got a real kick of the tire valve stem on the lid of the master cylinder !!. Yeah that Chinese carb is a piece of crap, and when that goes bad, you just throw it away like all the other Chinese junk... The last thing I want to do is raise my hood & see that, but I just have to get passed that, like everything else & move forward.... Besides you will still have your Rochester if you want it to continue to torture you.....
