Carburetor help

The priming trick will solve the long crank-time, but if your Accelerator pump is dead, it will not solve your after-start feathering.
Everytime your bowl evaporates dry, it leaves behind a varnish, which can and does eventually plug up or restrict the jets in the bottom of the fuel wells.And the only way to get it out is to have those passages "boiled out" with a proper carb cleaner. With the tree-hugger-environmentally-friendly chit cleaners on the market today, this often takes overnight to do a good job.
Up here, shell advertises that they put stabilizer in their fuels, to prevent it going bad. Might be true cuz their fuel seems to stay good longer.
I trick I used to use was to let the fuel in the front bowl drip out onto the intake beginning on Sunday evening, and on next Friday, I just filled it with fresh fuel. Voila no more varnish in the jets. ....... But now the intake looks likechit. I don't care, my car is a driver.
