[QUOTE="69ST, post: 120998, member: 5"] Looks like your issue is carburetion-related, that's a good thing imo. As much as I dislike the non-adjustable carbs, they should still work better than what you're now willing to accept. Trust me on this one, what's "good enough" at the moment...won't be for long, once the novelty (of having it running [I]kindasorta[/I] okay) wears off. Plus, there's no way the motor will be able to make full power with the choke partially "on". My guess, at this stage of the process, is a clogged emulsion tube (or/and other blockages). I'd expect to see a big difference from rodding-out the minuscule orifices with a thin wire. However, that, alone, may not be sufficient. That carb was designed & tuned before the current era of piss-like pump gas...and it was jetted on the lean side. It may be necessary to go one step larger on the main jet. Being a Keihin metered fuel & air leak, jets should be available - if not a complete rebuild kit. OTOH, if you're looking to minimize the bucks, it may be worth trying one of those cheap & cheerful PZ19 carbs that OLD CT likes. He's made a very convincing argument for them for the non-purists & budget-minded among us. The bottom line remains the same, there's no arguing against what works. If the solution turns out to be cheap, so much the better, if it works well...you'll be cheerful. :4: [/QUOTE]
