revving engine--kills engine???

Question

Went on a short trip today about 10 miles round trip. Everything was fine until about a mile an a half from the house. Had to shift down a gear and when I let out the clutch and gave it gas I had big puff of smoke come out from under the engine I was told by a friend. Every time I would give gas the engine would start to die and I would have to push the clutch in to rev up the engine to get it to move. Also it would die on me if I tried to keep going at a constant speed if that makes since.

Any ideas what is the problem could be? Could it be the carb or dist. I just don't want to hear that it is time to rebuild engine?

Its the 72

I had to do the dime thing myself.  Had to grind it down a bit, as Irecall.

Nope that looks to be in there nice and tight, the engine has cooled down if that would make a difference or notEdward Deerly wrote:

This little plug thing is a pain in the neck.  But, it can be temporarilyplugged with just about anything.  I have a fishing bobber cork in oursright now.  It's been there for a few months.  I will have to grind down adime and fix it soon.  I have used, in a pinch, a marble, held in place withchewing gum, to get us home.  I think, though, that the carburetor peoplecould fasten that plug in a little better.

just went out to the bug to see if i missed anything yesterday, every thing looks fine. Started it, ran fine, went on a short trip to get engine warmed up and the problems isn't there at the moment.

Any Ideas??

Guessing (from the fact that today it worked fine):

not getting enough fuel because tank ventilation is not working and eventually the fuel pump cannot get enough fuel out of the tank anymore. When it starts to act up, open the gas tank cap listen if you can hear the underpressure dropping and see if that has any affect in the problem

ignition coil going bad and not working when hot
