Re: Compression too high.
There is a technique to starting with a pull start,
If you want it to last.
I thought my pull start seemed well made, and have had no problems as yet.
I have been considering ordering a spare though, as it would also allow me to bench test motors.
A two stroke does not need to be yanked to start it.
It will usually take a couple of pulls on a cold motor to start it, but they only need to be long slow pulls, so that you don't stress the starting mech to a sudden stop when you run out of cord.
Don't shorten the cord if it breaks, and if it came with cheap cord, get some good stuff.
One of the best things about a shift kit is no peddle clutch starts and a pull cord.
Other wise they are a pain in the a**e.
