I installed an unused YF964S in my 55.1 235. It slows on the hills more than I think it should. If I pull out the choke about 3/8 inch, it does fine, or more like I would expect. Also, when I drove a choke vehicle in the past, I would be able to push the choke in after about 2 blocks. Now, I have to go for about 12 minutes and it still balks at the stop signs.
Is this an orifice size problem or some other adjustment I didn't do properly when I installed this clean new carb. Thanks-Scott
