So, I am in the process of rebuilding and restoring my a35. It has the 64cc Polini kit and the 19mm Dellorto PHBG Race carb, but It has never run as good as I think it should. It sat for a long time before I bought it and I bought it from someone who was the third owner of the bike. I have no idea who built it originally, but it needs some love. It is currently completely disassembled and being rebuilt (gaskets, seals, bearings, cables, brakes, tires, cleaning carbon build up in engine and exhaust, etc) while the frame gets powder coated.
I was reading through the PHBG wiki and came across the section about the "metal disk" in the PHBG carbs. I checked mine, and it was still there. So, I removed it. The bike immediately ran better, but not perfectly. I then read the section about the AN ( 4 stroke) vs AU (2 stroke) atomizers. It turns out that my carb has the 4 stroke atomizer and bushing. I understand that with the a35 reed block setup it is not necessary to replace the AN atomizer with the AU, but I am going to do it since it is a relatively cheap and easy thing to do. I also found out that the stock Tomos throttle has probably not been fully opening the slide on the 19mm race carb. I have ordered a new short pull throttle as well.
My question is this: since the carb was tuned with the disk between the jet and atomizer, the 4 stroke atomizer, and the stock throttle, how should I adjust the jets to compensate for all of this change?
I have noticed on the Tuning Spreadsheet that similar setups are running 100+ main jets. My current carb setup is a 70 main jet (if I'm reading it correctly see pic below), a 60 starter jet, a 45 idle jet, a W9 needle (on the lowest clip), and a 30 slide.
(Edit: Also the pipe is a technigas.)
I fear that this will be far to lean when I am able to fully open the slide with the new throttle and the other additions. Any advice for me? Thanks to anyone who read my novel!
