The issue in analyzing the 2 sentences is the ... between you and Will The situation and hence the grammar changes if the ... is supposed to be the speaker hesitating, in which case A and B both have 2 sentences, not a main clause and dependent clause A1. Oh, also, I wanted to ask you (something). The speaker wanted to ask before, maybe he is just remembering now. A2. Will you be at the political science club meeting Saturday? B1. Oh, also, I want to ask you (something). B2. Will you be at the political science club meeting Saturday? Or using IF to connect the 2 clauses A. Oh, also, I wanted to ask you IF you would be at the political science club meeting Saturday? B. Oh, also, I want to ask you IF you will be at the political science club meeting Saturday?

Want = present tense Wanted = past tense If you want to emphasize the present or past tense, select which one is actually so. This isn't so much a rule as what it is that *you* think is correct. Did you want to or had you wanted to? Both are correct, but it's up to you to decide if you want or wanted something. So your example B sounds better. And yes, you say "will" instead of "would". 'Would' sounds more like a favour is being asked, which is not what you're doing in this case.

I would usually say I wanted to ask you, as if I had thought of it earlier and now I'm thinking about it again. Previously, before I saw you, I wanted to ask you that. A bit more casual I might say "oh, and I was gonna ask you". B is fine but it's a bit more direct and I don't think I've heard it as often if ever, but it's proper english. Nothing wrong with it. "Oh, also, I wanted to ask you… would you be at the political science club meeting Saturday?" doesn't sound right to me. The tense doesn't need to match because the question you're posing is a separate sentence from the introduction.
