Engine takes 4evr to start and fuel comes out of carby

[crazy-latin-steven]

Hey guys another problem PLEASE HELP . Recently my orion 125cc doesnt want to start properly it takes for ever like 30-60 mins or more. I have petrol in it with the fuel tap on, keys on and kill switch on. I tried to start it and i heard a weird noise coming from the carby so i took off the air filter and tried to start it with the kickstart. When i kicked it petrol shot out of the carby and it does it until it starts. When its hot its easy to start so whats wrong with it???

i had the same problem, i was told that its because of a back flow of air from the intake valve/valves closing, if the engine doesn't start.
also, usually only occurs with engines that have rather "lumpy" cams

adjust the valve clearances

sidney is spot on check them 2000th to 3000th intake and 3000 to 4000th ex

sidney is spot on, if fuel is blown back out of the carbs, your valves are open when they should be closed thus making it hard to start...

All you need to buy is a set of feel gauges! costs around $15

Here's a video on how to check them:
