My engine came with a pullstart and centrifugal clutch. Instead of me buying a wide peddal kit ,I replaced my 8" peddal arms with 5" peddal arms from a exercise bike(but ones from a 20" kids bike might work) and i mounted my engine higher so my peddals will clear the sides of the engine. i had to make a custom front mount(i used a metal braket from a exercise bike). The rope on my pull start works fine(had it for a year),but i had a small metal clip inside the pullstart break,but i took it apart and used a small piece of wire to replace it and it works now,almost as good as new.im lucky it still works and is easy to fix cause there hard to find right now,but i also have the option to peddal start the bike if i need to.
if i had to buy a engine kit again i would have got a regular one cause it would have been easier to install on the bike and i always pull in my clutch when i stop anyway even thou i have a centrifugal clutch too. if anyone gets a pullstart i would reccomend you get a wide peddal kit,its easier in the long run. having the pullstart and centrifugal clutch adds around a 1 1/2" on each side of the engine.
