how do i fix the pull start on a quad LT50. it pulls but doesnt catch to start

also a yamaha 80 wont start at all, was told by motorbike mechanic to mix some oil in with petrol, shall i drain the fuel if i do how do i do it

The pull (recoil) start bearings are probably b*ggered, take it apart of have a friend look at it, it's a fairly simple job.

There's no need to drain the fuel, (double check it's a two stroke -- the exhaust will have a smallish tail hole and fat curvy expansion chamber(s)) estimate how much fuel is in it and pour in the measured amount, 5% oil should do it.

Ratios do vary greatly, do a search for the specified oil/fuel ratio for the specific quad.

As for not starting, it could be an electrical fault, do a complete diagnosis, or have a buddy take a look at it.

Do some online searching as for what to check for, doesn't have to be four/two stroke relevant, just start with the basics, fuel, spark, fuel air mix etc etc.

Hope this is of some help.
