Mmmhkay some progress. Doesn’t drip and the idle is a lot better. Too lean though, both the 50 idle jet and unmarked China jet are too small. Going to grab a 60, that should do it.
No clue what the timing is, the innova super duper timing gun decided to die. Light doesn’t flash anymore. Six months old - you gotta love overpriced junk.
Off idle is great and once it gets into the mains it runs really good. So I’m fairly confident that it’ll be just fine with a larger idle yet. Can’t wait to drive this thing with a bigger, non-clapped out carburetor.

Re: Carburetor Issue 32ADF
Ooookay, here we go. Time for another update.
I installed the 60 idle jet and let her rip. I jetted it according to another thread here with brand new jets from pierce manifolds. The primary main jet wasn't drilled at all and the car would receive exactly zero fuel when revving up. Awesome...so I went back to my old ADF jets and lo and behold, everything is gucci. Sort of.
Idle is much much smoother now. No dripping whatsoever and the car simply hums along as soon as you get out of idle. I set the mixture with the glass spark plug, it's bang on now. Now, my timing light broke so I set timing completely by ear. This turned out to be a blessing in disguise. Once I had a new light I held it to the engine and...I'm super advanced. Like 20*. If I turn the ignition to the marks (let's say the 5* mark) the idle speed tanks. Then I need to reestablish idle speed with the stop screw and guess what it starts dripping through the main venturi.
I then lined up everything to TDC and saw that the intake came is retarded and the exhaust cam advanced. Maybe the dpo messed with this or this is as close as you can get it on these engines, I dunno.
I'll throw a timing belt kit at it and report back.
For now, apart from a slightly wonky idle it runs like a beast. No pinging, knocking nothing. Maybe the marks are just totally off. How easy is it to install the pulley on these engines wrong?
Cheers
