On the 300 engine?
Check the manual for the decomp adjustment procedure—now I remember there’s no cable.
Possible the return spring is broken and you need a new one

I now have both motors in peices and it’s 3 am and I’m kinda just sitting here in the middle of all this and probably need to call it a day because everything is starting to get a little confusing haha. Thanks for all the quality advice you guys helped me out with you helped me a lot.

Cool info FF!!
So @Tymartinizgood ya got a couple engines there and a frame; not a waste of time necessarily. Got some options. Since you don’t know the history of the machine or what’s been modified, that could complicate the restoration.
Two schools of thought!
Restoration or modification? Remember David Bowie in Zoolander? “First model walks; second model duplicates, then elaborates.”
Another pitch again for you to follow Shadetree’s 1988 TRX300 restoration. Maybe we’ll be able to sort out your problems with that 88 engine and frame

A Fourtrax 250 and a 300 jug are the same , the cc displacement embossed into the jug is different on the two jugs , but that displacement is from the stroke , the only physical difference between the two jugs is the hole for the slack adjuster is bigger on one and you have to use the 250 adjuster on the 250 jug or grind the hole bigger to use a 300 adjuster
I have a 300 engine right now that has a 250 jug on it , so I know it works -----you can also use the 250 head on a 300 , but a 250 head doesn't have a decompression lever ------ the 250 cam and cam sprocket can also be used on a 300 , it is an upgrade as the 250 cam chain is heavier duty and the cam a bit hotter ---you can also take the output shaft out a 250 engine and put in a 300 output shaft and put the 250 engine in a 3002wd

So very important that you check the VIN regarding your saying it’s a 96 TRX300; you said the 1988 engine ran in it?
Okay so anyway see the parts link in my sig block? Click the rocky mtn link and select atv, then year, then you’ll see a list of quads with VINs. Search for your VIN and wallah you can determine your model year frame.
1988 project check this man out!
