Measure the metering lever height using a
depth gauge or scale.
Specified standard: 1.5
±
0.16mm
If the reading is out of the specified standard,
repair the metering lever or replace it with a
new one.
Check the wear of the contact portion of the
metering lever and the metering diaphragm. If
necessary, replace them with new parts.
Check the lever shaft, and if it is rusted replace
it with a new one.
Remove the inlet valve and check for dirt,
sludge, rusting and/or step-wear. Replace the
inlet valve if a beveled edge is found on the
rubber tip.
Inspect the clogging of the fuel passage in the
carburetor body and make sure there are no
dirt on the pump cover. If necessary, dip the
carburetor body and the pump cover in
gasoline for about 10 minutes, or clean them
using carburetor cleaner.
When setting the spring, be careful not to bend
it.
