Think i might have seized my motor trying to figure out how this could have happen. I haven't touched the needles since my last 4 runs, used the same fuel mix i used 2 weeks ago 25 to 1. The exhaust port and manifold was really scorched and loose even though i didn't here a different sound and pitch if they came loose when running. The pull start wont pull the flywheel.

could be a stone of some thing jaming the flywheel ??? how did it stop did it slow down then stop or just stop all of a sudden ??? allso what engine do you have ??

It's time to pull the engine and take a look inside. Remove the pull-starter first and see if there is anything lodged between the flywheel and the case (as previously suggested). With any luck, that's all it is. Otherwise, you may just have a nice looking paperweight.

Looks like i need a motor the piston was stuck in the the head and scratched along the sides. There was a lot of dirt inside the motor, wich must have caused it to seize, looks like the fillter must have sucked in dirt.

might be worth looking into some airfilter pre filters....outerwears make some good ones

when was the last time u replaced the filter?my bet is the foam cracked

blackrain

I actually have one but i must admit i haven't cleaned it or maintained it like i should have

outerwears are great for stopping mud but not fine bull dust...i once ran one in dusty conditions over an oiled kand n... 5mins and brand new top end was destroyed..lesson learned 1. k and n are rubbish offroad and 2. outerwears DO NOT stop fine dust

blackrain

Well i rebuilt the motor but it wont start i did a obr 28.5 race ported topend. My problem know it wont start not getting any spark, i checked the coil gap and connections. Do these ever go bad

bentley marshall

new spark plug ?? have you tryed another one i seen dud plugs from new ....did you clean and replace the bearings and seals in the bottom end ???

Sounds like you may need a new coil as well.

blackrain

Well looks like its the coil, i used the coil from one of my other engines and it gave me a spark and fired right up.

ouch man, that sucks....

it would be cool if it filtered fine dust. but they mearly just cuts down the maintance by keeping the larger dust particles away from the oil soaked filter
