Just an added note : I did check spark from the distributor to each plug, and all cylinders are getting spark. Though I've completely disassembled and cleaned with carb cleaner, compressed air, then simple green + ultrasonic cleaning, it might be possible that something is absolutely jammed into one of the channels.
Does anyone have a preference on carb cleaners OR/AND a way to clean the pathways physically
? I know some folks use wire to get in there, but the ones I've used that are so thin that they don't make it past any bends. Would something like THIS
be a good thing to try?
Also, I've adjusted the float a number of times, and this one (just before it's horizontal) has the fuel level just about 70%. I'm not sure which air bleed could be clogged. I'm reading about a "Purple Power Degreaser" on another thread on this thread
. I think I'm interested in trying it to see if I can get my airbleeds and power enrichment cleaned out for sure. (note, the first time I took the carb apart after this idle issue started, the power enrichment brass plug was inside the fuel bowl just floating around. I think it's possible that it fell out and something got sucked in and has been there ever since.)
Cleaning out the power enrichment seems tricky - it's plugged so how would you even get in there? The spring loaded system requires that you disassemble the whole thing somehow to get access to the channel.
