My friend has had a derbi moped in his garage for 8 years cuz the throttle cable snapped and he never bothered to fix it. Now i replaced the throttle cable and put gas in it, but it still won't run. What should i do? The gas is getting to the carb. because when I give it gas while giving it clutch during start, it is audibly apparent that gas is making its way in. Besides cleaning out the carb. and getting a new spark plug, what else could be going on?
