I have a 1987 TRX 250, it has been very reliable except for this starting issue. I have replaced the starter and gears numerous times and still having problems. I think the last time was maybe 2 years ago and this Quad is used very little. Starter works fine, when you go to start it it goes clunk, clunk, clunk, blah and usually starts. If it doesnt start after blah, it not going too. Like i said earlier, last time i replaced the starter and gears and virtually no change except it would start everytime, but it always sounds like something broke right before it starts. Just wondering if anyone else has this problem with the 250. One other note, the kickstarter does not work, and never has as long as i have owned it, could that have anything to do with it.

As it should be easy to see I am not a four wheeler mechanic so I apologize for asking for help, I replaced my OEM carburetor with a aftermarket carburetor and with y’all’s help adjusted the air/ fuel and it ran great until this evening and I noticed a smell of fuel I inspected carburetor area and found a steady flow at the vent line on the bottom of the carburetor so my question is is the float the only thing that will cause this problem? Before I installed the carburetor I checked the jets for tightness and they all seemed fine?

Is it possible to put a motor from a big bear 350 into a timberwolf? Reason I ask is that I have a timberwolf with a bit of a rod knock, and I have big bear with a bad rear end and axle with a good motor. So, is it possible?

Just bought a non-running 425 Magnum 6x6. Guy said previous owner had motor rebuilt (3 years ago or so.) It reportedly ran great but recently the electric start began failing and he put a new recoil on it which he broke immediately.
I get it home and put a new recoil on it and the pull is incredibly hard....so much so that I think I'm going to break the new recoil assembly. I also installed a new starter which won't roll it over either.
I'm thinking maybe a hydro-locked situation so I pull the plug and the motor rolls over fine with both pull start and electric start. The cylinder was dry however.
Checked the valve lash and it was right on at .0006".
Checked the compression relief spring on the end of the cam and the spring was strong and keeps the metal piece against the dowel like it should. The cam lobes look good from what I can see.
I have a small camera that I dropped into the cylinder. Could t get a pic of the entire chamber because of the angled engine but there are marks on the center piston and a couple of grooves once side of the piston top. I will include the photo.
Anyway....I'm at a total loss at this point. Not sure how to proceed and diagnose. Would sure appreciate anyone's help who might know what the heck is going on! I was able to get it to turn over about 5 times with electric start with compression tester installed which read 145 lbs. I don't know what else to do!
