Carb Cleaning with Pine Sol

Here's a 458 for your trouble. Now, I have been struggling with a project bike for a while now and it's starting to get down to crunch time. I'm supposed to be taking it on a bike trip in July but it still looks like this and I haven't been able to get it to run right.

I have pulled the carbs apart, cleaned them, put them back together, the bike will start and run but still runs like shit. It surges at idle, doesn't like throttle, and all around runs like it's running lean.

I have a rebuild kit that I'd like to install sometime soon yet I assume that the carbs aren't totally clean yet. A coworker suggested I soak them in Pine Sol. Has anyone done this? I've seen it on a few different forums but I'm not totally sold on the operation.

My plan: remove and disassemble carburetors. Carbs will be torn down until all of the plastic bits that can be removed are. (Floats and diaphragm slides are the 2 big ones I'm worried about) Fill a bucket full of Pine Sol, top with water to cover carbs. Soak carbs overnight to loosen up any extraneous goo. Rinse carbs with carb cleaner, reassemble with new parts provided in rebuild kit (bowl gasket, pilot jet/spring/o-ring, float plug), reinstall, victory.

I may be incorrect but I believe motorcycle carbs are small enough to just drop into a gallon can of Berryman's Chem Dip.

Yes, it's not the same hardass formula as in the 60's but it will still clean a carb well without turning you into a ninja turtle that is also chemically castrated.

Maybe. It's 4 individual carbs though.

It also looks like Pine Sol says not to use their stuff on aluminum now. Just FYI

I assume you've changed the fuel filter and added fresh gas?

I was having the exact same problem with my lawn mower. I cleaned out the tank, replaced the fuel filter then cleaned the carb again and it now runs really well except when you rev it all the way up it surges. It runs at 80% perfectly fine, but that last 20% is surging.

trip post? gah!

It's not my fault. Kinja told me it errored out so I tried posting again not knowing that it actually WAS posting.

Triple post is impressive. New gas tank, new filter. The carbs were really bad before and they're definitely better now but I don't know that they are where they should be.

new lines? I assume you have cleaned them then tried to run it, after a clean and startup are they dirty again? If not, it may just be an adjustment.
