thanks guys for all the help
Quick ?? I just picked the saito 72 from lhs, and was wondering. THey had it for 225 and noticed everywhere else is 259 . On the top of the manual for engine it says version 2002. Im guessing its a older version obviously ,why marked down . I asked salesman and he said he didnt think there were any changes.
I was reading around the net and came across this
On older engines there is a screw with a spring as you can see on the following picture of the carb on a Saito-56 engine.
The function of this screw is two-fold. First it holds the throttle barrel in place, second it sets a mechanical stop
for the movement of the throttle barrel . The screw is adjustable so that the position of the mechanical stop can be adjusted;
why this might be a desirable feature is a real mystery because it is usual for the servo to control the throttle travel.
More recent engines no longer use a long screw with a spring as shown for example in the two pictures below of the
carbs on Saito-82a and Saito-220 engines.

DO the new .72 haved this spring and screw if not I am thinking i need to exchange it for a new version.. It seems to me its just one more thing to go wrong on a engine...I noticed on the 82 it doesnt have the throttle stop screw and spring. was just wondering if the new 72 dont have it either. Thanks again for the help \
