Stuart Im about 99.5% sure it isnt fuel related. If anything it started with the onset of our cold weather in Oct-Nov. Shes garaged except when I drive her, so other then condensation there was no chance for water in the gas. I almost always fill the tank up on the way home also, so condensation is not real likely in my opinion.
The day before all this I swapped out the cap and rotor and it made a night and day difference. I probably put 150 miles on her. Then the next day, struggling like mad????
I did take the YF apart and to my dismay I found nothing inside, looked and blew out all the passages with no change in behavior.
Thats when I thought to rebuild and start fresh with a Rochestor B. So I spent a few days soaking and cleaning that carb. Blew out all the passeges and bolted her up. I get a steady squirt of fuel and as stated above there is a small amount of fuel puddling in the intake and I rebuilt the fuel pump since it appeared I wasnt getting the appropriate amount of pressure to the carb, theres plenty of pressure now.
Starting fluid (as much as I hate the stuff) didnt have much effect. I occasionally got a stutter, but nothing more then a split second or so.
Im back at it once again... Thanks, Jeff
