As mentioned in the first post, the little red Corvette has done a lot of work over its 24-year life. In recent years, I've attended to a couple of more involved maintenance items over and above the usual oil changes and blades.

The first of which was to refresh the carburetor. While the engine was starting and running, it was lacking throttle response and would stumble a little going from idle to full throttle, while also having the occasional mild surge. To get 22-years out of the original diaphragm is quite remarkable, I assume from regular use keeping it pliable. When we result the Morrison's engine, the carb wasn't touched, so this would be my first attempt at a carburetor repair.

So, I ordered a carb kit, and new governor springs for good measure.



To gain access, the air filter was removed and the throttle disconnected, followed by breather tube. The two bolts holding the tank in place were then removed and the whole carb/tank assembly is wiggled away from the intake manifold.







While not necessary, I also removed the blower shroud to inspect and clean, the first time off the engine since it was made.



On the bench, I started work removing the carb from the tank and getting everything clean.







The old diaphragm was ok, but clearly aged. The new parts were then installed.







I then installed the new governor springs and inspected the intake manifold as these have a habit of coming loose over time. The refurbished carb and tank were then reinstalled.










An oil change and a little clean, I fired it up and once again had a stable running engine!
