How about your vacuum advance ?



Good question! Mod5v asked about carbs, and that's where my mind went. D'oh!, to quote Homer Simpson.

Hey Mod5v, I thought of one more thing. If you opened your secondary throttle plates to get the primary t-slot/throttle plate relationship corrected, close 'em back up and drill holes in the throttle plates instead. While opening the secondary throttle plates will allow you to fix the priamry t-slot thing without any drilling, the now-exposed secondary t-slot will allow fuel to be sucked in during high vacuum situations (coasting). Most folks prefer not drilling their carb, even if it means some fule might be wasted. You seem to have other priorities. I'll let you decide if the risk is worth the gains. Exposed T-slot wastes fuel.

Your engine is small enough that this is probably not be an isuue, but I'd check it anyway. Again, it keeps to your low budget requirement.
