engine froze now unfroze but wont engage

[betoalvarez]

its a 49 cc from powerking on ebay.
yes i can turn the engine by using the lil tool on the drive sprocket nut. thx

in an earlier post he said he broke the mount, you can drill the broken mount with a left handed bit and unscrew the stud and replace it and then ur done. or if the tip is coming out you can use a pair of needle nose vice grips. if i remember correctly thats all thats wrong with his other kit

 

[betoalvarez]

sorry a long post got deleted anyways..

old motor is cracked on the whole left side as well as the mounting

it still will not engage even when i tighten the screw on the right side gear. (new motor)

im thinkin' maybe i should switch out the gears and clutch from old motor to this 1? how would i go about this? thx man u guys even responding is giving me hope..

 

[betoalvarez]

nope..

hmm i can turn the gears and yes the piston moves up and down.

what im trying to say is that, the bike rolls freely AS IF i had no compression(spark plug out) BUT i have the spark plug IN and the bike just rolls freely and piston moves up and down. oh yea my kit only came with a sprocket puller no small gear tool. thx

sounds to me like you have the clutch cable too tight, cause if you have the flower nit tightened all the way, the arm is yr only other possible problem other than the flower nut not being tight enough, if u feel the flower nut is tight enough its probablly the clutch arm, move the little brass fitting closer to the end of the cable and go from there, with the clutch, its a lot of adjusting as breakin goes, it might not have even been the gas, you might have broke in the clutch a bit, thats what JUST happened to me, right norman? lol this would be the thing to try before you do anything else


edit i read the piston moves, my bad

 

[betoalvarez]

ok yes it does move freeley, i not only seen the piston move when i had the spark plug and top off ,but with the top and plug back on i can hear it move up and down. i think it might be a clutch issue? i can't start it because, theres no resistence its too losse but i tightend the clutch as far clockwise as possible..i have to go to work and won't be back till 10:00 tonight thats like 12:30 your time, im in california. thx!

 

[betoalvarez]

no i have had problems with the clutch arm on my last 1 so i know about all that. the cables not even attached as of 30 minutes ago and still it moves too freely. thx

Maybe the ring are toast and thus, no compression even if the piston moves.

I think the cylinder will have to come off to check for damage.

EDIT: Ah, Norman has already suggested this. My bad.

I tried to follow this thread but it's too hard to figure things out. My take on this is that his clutch is slipping and he can't bump-start it. Am I wrong?

 

[betoalvarez]

i guess I will take the piston out but how do i check for damage? there is no compresion, even when the spark plug is in.

no compresion

cutch cable is good

tightend the flower nut on right side furthest it will go

im gonna go see right now if i can start it, theres a big hill right outside clutch cable connected is no help either way its like in the middle of engaged and disengaged. and will not tighten or loosen. thx i'll keep u posted.
