Wg-5 appears to be off a Echo saw. It has the higher side screw but different throttle/choke levers. Wg-7 looks like a Husqvarna 3120/ Partner cutoff saw carb. No High side screw but does have the pilot hole. Wg8 and 9 look to be the same. However some have the blue piece between metering diagram cover, which vents to atmosphere on the face not with the cover. Neither have the Hs screw but do have the pilot hole in body. There is a Wg model for the Ms880(wg12) that has the Stihl throttle lever not the cable set up like Husqvarna. Wg2’s are no longer made, they do not have a choke but have two fuel inlets and used a primmer bulb. Wg3, I’ve never seen but I believe came with high side screw and choke. Wg4- I’ve never heard of one. Same with the Wg6. A Wg 8 looks to be popular with the Rc planes.

WG3 and 5 are echo carbs. WG4 are oly/mac990carbs. WG12 are stihl carbs. The rest are for Husqvarna. 2,3,4,and5 had the larger inlet needle like many carbs of that era. WG2 were sought after by hotsaw builders because of the only one to have a larger needle and having the largest throttle bore of all of the by 1/16 for the 3120, which most don't know or was robbed for parts by improperly enlarging the inlet. I can't count the amount of carbs I have been sent to fix that issue. It's my trade, not the guys trying, I've seen about it all. Carb modding at one time was no secret. IMO Marcel shared it all with his own paperwork, but the owners of this paperwork act like it's not shareable. I never copied what little I seen from Marcel, I just did my best to improve it and not copy. With my trade I was able to. Turning a 8 to a 2 was easy for me cause I even went further. Guys like mVp, Benny, big Dave, etc paved the way. Young man up north has turned it all up to a new level! Forums act like putting in a hscrew is voodoo! I've repaired all those too. My own nozzles, my owns screws, my own seats, and blocking off patterns to go back to basics.Trenching the wet side of a carb for just a hscrew addition is like Bridgeport porting, more gimmicks]!] I have photos of wg3 and two wgs2s in my hand today but cannot upload. Sorry for the rant. Lol #Post#: 90438-------------------------------------------------- Re: Walbro WG info By: SquareFile Date: January 14, 2024, 1:20 pm --------------------------------------------------------- These modern day worksaw builders are the worst at adding a high speed circuit to a wg. They are all different. Feeding from different orifices, not knowing shit. I never cared what carb I had. All the same by the time I was done. I still laugh at trenching a gas carb that still has the small inlet needle, ELEMENTARY, at best. #Post#: 90440-------------------------------------------------- Re: Walbro WG info By: Chainsawrepair Date: January 17, 2024, 8:18 am --------------------------------------------------------- WG 2 3 resized for Shawn. My WG2 done by MVP back in the day. When I took this MVP 166 on trade. How it looked before thorough and rebuilding everything. *****************************************************
