    compression too high

    Cleaned the carb today and it seems to try to start a little better but still won't run for more than a few seconds. The plug is fouling too. Backfiring is not very bad now.

    compression too high

    The carb boot looks pretty good. Can't see any cracks anywere. After we rebuilt it we pulled it around with another four wheeler and it did start and idle but would barely stay running and wouldn't take any throttle. I think I'm going to take it to my local yamaha shop and have them look at...

    compression too high

    the timing is set perfect. i've checked it many times. after i did some research i thaught it might have bent a valve because when i got it the cam pin had broken and fell into the crankcase. that was why i decided to rebuild it but when i had it apart the valves and everything looked fine so i...

    Just rebuilt my warrior, still wont run right

    Well I think I have narrowed it down to a fuel issue. It has great spark and great compression.it seems to be getting too much gas because it is always fouling the plug. I think this is also causing the back firing. What could cause this and what should I do to fix it Any help is appreciated...

    it has very strong constant blue spark. also, it always seems to flood itself for some reason. after trying to start i will pull the plug and it is soaked with gas.

    Just rebuilt my warrior, still wont run right

    Ok, so I got my last parts installed. Turned it over and got alot of back firing through the carb and exhaust. It started for about 3 seconds then died. It has really good spark and seems to be getting plenty of fuel. Timing is set perfect. Valves are adjusted. Carb just been rebuilt. and a new...

    Just rebuilt my warrior, still wont run right

    the guy who had it before me had removed the old lever and replaced it with a aftermarket one. i found the clutch sensor wires cut off down by the harness but could not find the brake sensor wiring. so i dont really know what has been done to the parking brake. i was thinking i could just find...

    Aren't these supposed to come apart?

    Mine was doing the same thing when I replaced my starter clutch. I took the six allen bolts holding the starter clutch to the flywheel out and used a big flat head screw driver to get it off of the gear. It came off pretty easy that way.

    Just rebuilt my warrior, still wont run right

    Well its been awile since I have done anything to my warrior. I got a new starter clutch and a new cam chain and got them installed. I also got my oiling problem fixed. I had lost the pin that connects the gears in the oil pump. Im still waiting on a few other parts so I have been trying to find...

    Just rebuilt my warrior, still wont run right

    The cases should be pretty clean. I spit the cases to get out a cam pin and some washers the previous owner must have dropped in. the bottom of the cases were really dirty when I pulled them apart so I flushed them out with deisel. The engine didnt run too long. Only for about ten seconds...

    Just rebuilt my warrior, still wont run right

    Ok, so I cleaned the carb and it didnt fix my problems. I've decided to order a starter clutch and timing chain before I try anything else. I found out my warrior is actually a 1992 instead of a 1998. My wiring diagrams dont show a parking break on that year so I guess that isnt a problem. Also...
