Brian & Tennis Shoes,

It seems you both think alike for the problem being the reed valves.

Your symptom of 'burpin & fartin' out the carb can come from compression
escaping the cylinder(s). The reed valves are the only thing keeping the
compression where it's supposed to be.

If you lift the heads (usually not hard to do) you might get a nasty
surprise to find one or more rings broken or gone altogether.

Brian,

I took a compression test before I even started on the motor as I
didn't want to sink money into a boat anchor rather than motor. It ran
130-145 PSI on three separate times (just oiled, 2 days later, 1 week
later). It was also for that reason that I didn't think the reeds were
at fault. But the reeds could leak (or seep) but the compression tools
wouldn't know that due to the check valve retaining the readings in the
gauge.

If the carb seats and the reeds do not cure the problem, then I pop the
head to look futher.

Thanks again for the advice,
Mike, Pensacola, Florida (Gods waiting room)

There may be part # on the parts. A small engine type might have an
assortment on hand. Varnish can build up in the hole for the needle,
causing it to stick. Clean with a cotton swab and camp stove gas. Dry
with air. A proper carb man would clean out every orifice with high
pressure air.

I have a badly worn carb that would not behave until I wired snug
external O rings above and below the butterfly throttle shaft with
brass snare wire. It was so loose it wiggled and upset the mixture any
where near idle, or, it seems, whenever it chose to.
