I acquired a 1991 TRX250X last fall.
It ran when i got it but only with about half choke always. I tried adjusting the carb a little and go tit running with about 1/4 choke. Then I put it away for the winter.
I tried starting it the other day and it wont start, nothing when i kick it like 30 times.
I checked the spark and it looks good.
Short of going thru every electrical connection, could it be the carb?
Its an unknown as it is since this thing was messed with, has an aftermarket pipe and gas tank already. I wonder it the carb was replaced and or messed with. It did pop pretty bad in open throttle.
I tried finding a replacement carb for it, but they only sell 85-87 from what i can find.
Is there a carb of a different year or model that was the same that i can swap in, with some modifications maybe? Dont want to go to the dealer since that will prob cost over $200.
Thanks for any help you can offer.
Carb most likely is a big part of the problem. If the spark plug isn't new, replace it with the recommended plug only.
Start by finding a service manual for your model. It will tell you which carb was originally installed. Then, remove the current carb so you can see if it is the original (it should be stamped with a number or name) or a replacement. If original, you would be much better off rebuilding it rather than replacing it with a cheap one like the ones sold on Amazon and eBay. As for the rebuild kit, it is best to use a Shindy or similar high-end brand. A carb is not the place to pinch pennies.
I checked partzilla.com and they do not offer a full replacement carb but do have most of the parts available. At partzilla.com if you click on a part name/number it will take you to a page that will show you all the compatible models. This should help you find which other years are compatible with your ATV.
Clean the air filter. Check that replacement gas tank to be sure it's clean inside and the petcock is allowing proper fuel flow. If gas has been sitting in that tank since last fall you need to empty and clean the tank and fuel lines.
Follow all the general maintenance recommendations in the manual. It's always best to start with the simple things first and work out from there so you don't end up buying parts you don't need.
I hope this helps you. Keep us posted.
