To the question:
which carb to use, I have one 2 needle carb and one 3 needle carb with black anodized throttle slide. I thought I found out here that the carb to use is the 3 needle carb with black throttle slider, but my vendor told me that he got the 2 needle delivered from GO to change out the 3 needle.
The engine is a GO GX2 5RHO
Pls help me out
Regards from Sweden, Johan
Hi Johan,
You can use either carb, but the 3 needle was the production carb for the GXII-5RHO in it's last year of manufacture.
The 3 needle is a good carb.
Don't adjust the 3rd screw from the factory setting , and just treat it like a 2 needle carb for tuning.
The 3rd screw is not actually a needle, but an adjustable fuel tube. It is factory set for the best engine response, so mark it for reference, and just leave it.
You will get better power and response from the 3 needle carb on the 5RHO motor.
Hope that helps.
