YZ 490 is in but wont start

[mark]

well i got all the brackets welded in and rattle canned them for now so that they wont rust. i have the whole motor in now and just hooked up the carb kick starter, wiring and fuel tank i gave it a few kicks but it just wont start. i checked for spark and it is getting spark. so i dont know :/.

i havnt put the throttle cable in because the one i got was damaged so im waiting for a new one to come in. there also seem to be quite a bit of play with the kick start (it doesnt start to turn the motor untill it is half way down). Im not sure what causes that to happen either.

one last thing is it seem to me that the clutch is jammed. i pulled the rod out because i thought my blaster one would go in so i wouldnt have to mess around with the cables. but they were different sizes. but anyhow when i put the rod back in the tranny i cant pull it it to disengage the clutch. i dont know if i did a mjor eff-up or if it was locked like that before. but anyone know how to fix this?

thanks

well thats what im asking it is supposed to be rebuilt but i think it needs crank shaft bearings

humm do you got big spark or a weak one , and if you got big spark its maybe just carb issue put some gas in the spark plug hole if its start then its carb issue!!!!

alright ill try that ad i have some starting fluid for gas engines but does any one know if it is safe to use on a two stroke?

 

[randelator]

no dont do thats never use starting fluid on 2 stroke never !!!!! usu some gas of your gas tank,the point is just to know if your fire is ok and if indeed your carb is the probleme!!

 

[mark]

ok just checking to make sure ill try putting the gas in ther and see what happens

there also is no exhaust on it yet so i dont know if the lack of back pressure would prevent it from running

 

[randelator]

yeah dont start it whitout exaust,you could blow your engine in a second, i saw it happen twice on 2 stroke!!!!

 

[mark]

ok ill wait then good thing it didnt start lol

 

[randelator]

yep put thats thing together and then do your testing and if you need further help i will be happy to try to help you , keep up the good work!!!

[randelator]

and that was without the silencer I couldn't edit my post

 

[randelator]

it dont happen all the time but 2 stroke need back pressur to work propely!!!!

 

[dirtyblaster]

yeah two strokes will not work or not work correctly with no backpressure

 

[randelator]

yep!!!! thats how 2 stroke work
