G9 oem jets

mta5002414 · 09-18-2022, 10:19 PM

Just got a 1993 G9 last Friday. It cranks up cold with only about 2 secs of choke then runs well. I suspected it was rich because the PO installed a new air filter and spark plug. Yet it needed very little help to run when cold. I pulled the plug and it told the tale.... pig rich. (The idle/low speed jet is only 1/2 turn out too) I cant make out the numbers on the main jet. But even if the jet number is right someone could've reamed it over the years. When trying to clean it if ethanol fuel had clogged it up.

Anyone know the oem jet numbers/sizes?

thanks

Btw, I cant seem to find the spec and a procedure for adjusting the float. Most I've done were checked at at angle just off vertical... but I dont want to assume

The parts that you need are available from Partzilla or ebay...
