1. Custom jets for the WG carburetor

See the high altitude modification page for information and how to install the correct sized jet for your application.  The most common high altitude jet is #112 for 80cc engines or #125 for 130cc engines.  These jets are not mass produced but custom machined in our shop from blanks made by the Walbro factory in Japan.  These jets are expensive but are made to a tolerance of 0.01 mm.  The factory made jets may vary about 0.02 mm.  Note:

2. Carburetor rebuild

Ultrasonically cleaned & rebuild of a Walbro or Tillotson diaphragm carburetor – includes replacement of the parts supplied in the OEM kits and a new metering lever spring, if yours is out of specification.

After assembly, the pop-off and rest pressures will be measured to ensure that they are within specifications.  Adjustable jets will be set to the factory recommended values. 

Note: Rebuilding your carburetor may not fix other underlying fuel problems, such as poor quality gasoline, clogged/defective inline filters, incorrect jetting, leaking fuel lines, etc.  The carburetor must be adjusted for your climate, altitude, and engine condition to work properly.  This page has the details.

Carburetor must not be damaged e.g., bent low speed idle jet, throttle plate, choke lever or plate, etc. and be complete.  There is an extra charge for any missing or damaged parts that are not part of a standard rebuild.

Shipping your carburetor:  wrap the carburetor with bubble wrap or heavy paper and put in a a small box.  Do not ship in a bag.  Send it USPS 1st Class small package, USPS Priority Mail, UPS, or FEDEX to the address on the contact page.  Turn around time can be a few weeks if we are busy training or traveling we will let you know.

TOTAL PRICE IS FOR U.S. ADDRESSES ONLY.  FOR ALL OTHERS, PLEASE CONTACT US.
