Hi
i hope if anyone could help me with my chinesequad
the problem i that the piston moves and gives compression when i remove the sparplug but when i attach the spark plug or put my finger on the sparkplug hole it does not move or give compression.

 

Does the starter spin when you have the plug back in, but the crankshaft does not?

 

Week battery? have you checked battery

 

No,the starter does not spin nor does the crank shaft.

 

i dont think the battery might be the problem as i had attached it the my car battery.

 

Both of them only spin when i remove the spark plug.

 

It is either the battery, as Zrock said, or the thick wires from battery to engine earth, or battery to solenoid, to starter motor, one of them is loose or corroded. There is a slight possibility of a faulty starter motor, but they usually work, or don't, rather than being dependent on loading.

 

Right.
well yesterday i was able to start it using two fully charged car bateries.it started the first and second time i tried to start it but was only clicking the third time i tried. I hope if that also would be able to give you some clue.

 

If it is a loose or corroded connection it will get hot when the starter is being used. To check for a faulty starter, put a test lamp between the negative post on battery and the positive post on starter, press start button, if lamp lights but starter doesn't turn, faulty starter, if solenoid clicks but lamp doesn't light, faulty solenoid. Only do these tests with a charged, good battery.
