Hello ALL,
I purchased a 2001 Polaris Trailblazer today, and when I got it home had troubles starting it. It being a 2 stroke, thought it might have a filed plug. So i pulled the plug and changed it. Looked normal. I got her fired up and was warming it up going around the house. Noted when the machine was idling it was ready to stall. Thought it might need adjusted.

Ran it around the yard a few times and then took it across the field. On my return home the quad just stalled. Could not get it to fire back up. Sounded like it was trying too but never did.

I pulled the carb off the machine and took it apart. To my surprise the carb was very clean and had new guts in it. Prior owner told me he had it rebuilt by his friend. When I was starting to reinstall the carb i noticed the oil injector hose was not connected to the intake injector. Hose was broke where it made the elbow. I found a extra hose i had and redid the line. BUT... i cannot get it to fire up still.

Did the motor get screwed up from this? I would imagine if the motor seized then it wouldnt turn over at all. Does anyone know what may be the issue? I would appreciate any assistance you can offer. If the quad is still able to run would love to keep it. Hate to return it unless its jacked.

THX

Kevin

a compression test would be quick way to see if the engine is damaged otherwise it could be fuel problem like a plugged filter

2x on compression test, no oil for how long and how hard did you ride it when you got it lit?

I took the gas line filter off and emptied the fuel out of it. Blew on it on both sides and felt a breeze.

When I road it at the time of purchase we only drove it shortly since his yard was small. Didnt get on it hard there. When i took out at my house, was never on the throttle hard. When we went to the field would say 1/2 throttle. Never was at top speed. I would guess no oil for bout an hour.

Soon as i seen that hose hanging i knew there was an issue. Heart sunk.

I would say if you got lucky, you will at the very least need rings. You will have to check the compression, and decide where to go from there.

I called local shop to see how much it costs to get it done. Only few bucks, but i gotta haul it there LOL... Trying to get my hands on a "borrow" tester so i dont have to pay for one. Seems like all the ones i seen at stores are starting at 75 bucks and up. What is the magic number i should get when i do it if its good? Or is there a range it should be in?

Got a Northern tool or sears nearby? They should have a tester for about $30. And a good shop should test it for free. Take out spark plug, put in tester, crank over and read. Takes about 2 min. Need at least 100psi for it to run. 125-130 would be normal for it.

I got a compression tester, but was not able to thread it on since there was only like 3 inches room between the gas tank and the plug area. One I had was hose that attached to the gauge. I'm taking it over to the local Polaris Dealer tomorrow after work. When i spoke to there shop people, they seem to think it was only top end that will need to be redone. So I am hoping that will be all. Everyone that hears it turn over say bout the same thing "sounds likes its got some compression, just not enough to fire"

So i will find out shortly what it will take to fix.

THX all for your help with this so far.

Sorry I havnt replied back to this thread yet... Been waiting on my ATV Shop to give final answer. It was the top end that was bad. Shop had to send out to get machined and then new parts. They put it back together and it fired up.

Was pretty noisy i heard, so they thought the bearings were bad for the crank. They are waiting on them to come in and put them in.

Hopefully i get quad back soon... Kids & Wife cannot wait to go riding on it.
