Thanks guys. Well, the tank has just been cleaned and sealed, so I don't think it would be the tank. It has a brand new fuel pump on it and it is working well, you can see the fuel moving in the glass bowl when it is running. I just put a new fuel filter on it about 3 weeks ago, but that was B4 I cleaned & sealed the tank. I guess it's possible it could be plugged. I actually did wonder about the coil though, because when we first got the new engine running, we had a similar problem at that time and we changed out the old coil (I didn't put a new on it at first like I should have) and it ran great. It has a new coil on it, but I did wonder if by chance it could have went bad. I don't know. I thought tomorrow I would check the points gap, and some other things & go from there.
Thanks!
