thought i'd try regular gas

 82 750 seca doesn't rev when it's time to push in the choke. other
than that i don't see a problem. is there something i should look for?

 
Dirty carburetors. Go to Wal*Mart or any well-stocked auto parts store
and buy a can of Berryman B12 Choke and Carburetor Cleaner for about
$3.00.

Buy the non-aerosol can so you can measure four or five ounces and
*carefully* pour it into a full tank of gas.

Don't get any on the paint, B12 contains toluene and acetone and MEK
for quickly cleaning gum and varnish out of carburetors

Then go for a slow ride using very little throttle so the engine will
have to suck gasoline through the idle jets and idle passages.

You'll know that the B12 has done its job when the engine idles faster
when you stop. If some previous owner has adjusted the master idle
knob to compensate for engine stalling, the engine may idle at 4000
RPM when it's hot after the B12 does its job.

It helps to know where the master idle knob is before you start out on
this carb cleaning ride.

B-12 is for minor issues. When you want the job done NOW and done well
you use seafoam...you know nothing wiki bandit.

Seafoam is really good at..........marketing.  The stuff in that can that
they have brainwashed you into paying ~$6 for probably costs them about 75
cents to make.  Not that it is bad or totally useless but there are better
things for cleaning carbs and B-12 is one, that is much better and widely
available.

If you used a product that was really good, there would be no need to "rinse
and repeat several times".

 

And I have no use for grown men who get all giggly over British
"humour"
and feel the need to repeat it endlessly.
