1. Custom jets for the WG carburetor
These jets are custom machined by us to a tolerance of 0.01 mm from blanks made by the Walbro factory in Japan. Minimum jet size is #098.
See the high altitude modification page for information and how to choose the correct sized jet for your application. The most common high altitude jet is #116 for 80cc engines and #125 for 130cc engines. Walbro jets can be temporarily modifed for testing purposes in order to help determine the best size for a permanent jet.
Note: please contact us for a discounted price if you need to order more than (1) jet OR if you need jets shipped outside the U.S.
- Price $14 and includes FREE shipping to U.S. addresses only
2. Carburetor rebuild
Ultrasonically cleaned & rebuilt. Iincludes replacement of the parts supplied in the OEM kits and a new metering lever spring, if needed.
After assembly, the pop-off and rest pressures will be measured to ensure that they are within specifications. Any adjustable jets are set to the factory recommended values. The metering lever is set to the correct value for paramotors.
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.
No other process can remove the accumulated gum and grime like an ultrasonic bath. Invisible deposits inside the small openings in the carburetor affect the jet sizing. A surface film of 0.01mm is enough to change the air-fuel ratio.
The carburetor must not be damaged e.g., bent low speed needle, 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 to the address on our contact page. Turn around time can be weeks if we are busy training or traveling. We will let you know.
