As a long term poster on car forums.....fantastic feedback....thanks (for someone that may ask, no known neurological issues other than flying without an engine....;-))...extra dots may be likened to a pause when actually speaking to someone...

I was thinking either a collapsing fuel line, tank cap that wasn't venting, possibly a bad diaphragm (wasn't sure if float or diaphragm).

Spark plugs....not a typical issue....very low on trouble shooting list. Sounds like fuel, but short duration.

Whenever you find the issue, PLEASE post back on resolution, too many forums someone posts an issue, many possible fixes, usually never feedback on resolution.
Help the next peep that actually searches.....

Thanks.
