Thanks Mike I think I will get a rebuild kit and pull the venturi out
on my next days off, I might as well do it as it is bound to be a
problem in the future. ( if not the problem now)

I did notice that if I choke off the air to the carb the idle picks up
real nice.... I do have a good working choke but damn a manual choke
would be nice right now.

Funny you should mention that.... I work in the control room of a
major Shell refinery here in the Edmonton area. I run the control
panel for the second largest vacuum distillation unit in the world,
prior to this job I worked in the control room at Syncrude running the
2 largest fluid cokers in the world. If you have ever burned Shell gas
or Esso gas I probably had a hand in making it. Nine times out of ten
it is not the gas coming from the refineries that is the problem it is
generally the way it is handled or stored that is the problem. Many
places allow water or moisture to get into the in ground holding
tanks.... when you find a place like that avoid it....... like the
------ station just down the street from me. :)
