I got my no spark issue sorted out, got it running on the old aftermarket carb, but it didn't want to take throttle even after cleaned it, didnt really want to waste time on it, so I order a new one which is on its way, so not much to post here, but I wanted to start a new thread. I am stating to clean up the plastics thought I might as well do that while they are off, they were a mess tree sap, bird dropping, mold and what ever. Washed them good and got all off so I could see the oxidation , decided to wetsand with 600 grit waterproof sandpaper, and used Armour All instead of water. I figured it could put some of the moisture back in that was lost from sun exposure. Working fairly well I will keep going finer on the grit and see if it will polish

These are several that fit not sure if auto zone has them but they are standard brands, Autozone-WalMart carries Fram, Oreileys has Wix, Walmart has K&N. Fram 6017A, K&N 303, Wix 51358.

the best part is that is literally my backyard. once I get done with getting my beehives going and other such stuff I'll be hitting the woods, theres some stunning places and views here. Part of why I just can't be pried out of the rocky mountains for long without being homesick.

I did notice a few differences between the OEM and aftermarket carbs: The throttle return spring was stronger The idle adjusting cable was larger The mixture adjusting screw was covered up with brass plug The choke plunger was made out of aluminum with an O ring and a little longer with a different shape, and stronger spring I didn't take it apart and compare the internal im sure there are more differences there. Since most aftermarkets don't have jet sizes on the jets hard to compare without a measuring tool I don't have.

I worked at a bike shop in my early 20's and got to ride my share of Banshees, Warriors, and Blasters. Super fun quads but way out of my affordability range at the time. Years later when I could afford one I didn't have space so I got a YZ250 instead. We just moved to the country now and have plenty of space and some land so a work quad makes sense. Neighbor gave me a Polaris Magnum 425 so yeah that's do. I'd still like to get a Warrior or a 400EX eventually. Got too many projects though and my 85 4runner rock crawler project is getting priority for KOH next year.

No guesses! Its the one on the left. It is kind of foolish wasting this much brain power on a carb, I should just get the cheapest one stick it on there and go, been there done that didn't go very far, after going to this much trouble I do want it right.

Got my carbs in an OEM, and an aftermarket, I have a few side by side photos, just for fun can you choose which one is the Mikuni:

Got the exhaust all delisted and back together, ran out of black high heat paint so I found some red engine enamel probably not my choice but its what I had, may change it later. Still working on the plastics they cleaned up very well but they have had a rough life had one crack that I repaired and a lot of spots where the plastic had been flexed and its a lighter color there only way to hide that is paint and I don't really like to paint plastics, I have wet sanded from 220 to 5000 grit and they will polish nicely, still not decided what im going to do. The carb will be in tomorrow so I forget this for a while, but I will have to put the back plastic on to fit a seat to see if it drives. You can see the areas im talking about lower right, middle right and upper left. Oh and don't laugh at my mobile work table, there is an interesting story behind that.

I decided the exhaust needed a little attention while it was all apart, very rusty, surprisingly i got them all off except 1, the one closest to the exhaust outlet that holds a heat shield in place, the head on the bolt was not even 10mm anymore, I didn't push it because if that one breaks its the only one holding that part of the heat shield in place and I probably would not be able to get the stud out. I would like to, just to clean the rust out, might keep trying but its there. Its always a challenge getting 25 year old exhaust bolts out. I tried cleaning it without taking it apart, but I could only imagine how much mud and rust was on the muffler, don't really want that to rust out. The 14mm that holds the muffler to the frame were stubborn and needed a little persuasion to come out, of course all the original metal was covered in rust, I will just get the rust off and repaint with high temperature paint.
