                over the winter.  I didn't have any trouble getting the

                test it by starting the car cold, driving it around my

                garage and trying to restart it after 20-30 minutes.  If
                it won't start I can pull the plugs and take a look, and
                also test the battery to see if it wasn't holding the
                charge.  I can also check compression at that point -

                it might be the coil - I had read that sometimes after
                the coil gets warm it can cause intermittent problems. 
                If that was the case I'd think the car wouldn't run
                after being push started, but I'm far from an expert.  I
                was just guessing at the carb because I've never been
                good at tuning carbs, and it's the last thing I changed

                                            don't drive too much in cold

                                            that the problem last summer
                                            could have been vapor lock,

                                            have worked if that was the
                                            issue.<span class="yiv4564730960Apple-converted-space"> </span></p>
