Tru,
Sorry to hear about all the minor problems that you have which have added together to become a real problem. If the carb is cracked, I would just replace it with a new one of the same type. I am guessing the other issues are not major. When I had my carb built and dynoed in Los Angles, the bank was very nice about loaning me the required money. When I sold the car I paid the loan off.
Ernie,
If 50% of the the enjoyment is working on them, 75% is frustration with them, and another 32% is just getting disgusted, why not throw out the working on them.
