Using brake cleaner (easier on plastic than carb cleaner) and air you can begin by blasting out every orifice in the carb with brake cleaner then blasting it clean with air, then doing the same to each part as you reassemble the carb. Finally, you can remove the fuel inlet cap to expose the filter screen under it, and remove the filter screen. Now pull the white float, and float needle out. Use something small like the end of a paperclip to slide that out. You'll see a little pin holding the white float in place. Next you will remove the two screws holding the black bowl at the bottom.

You can turn it upside down at this point to drain out the excess gas. Remove the fuel line, then pull off the carb. Remove your K&N Filter, loosen the carb retaining bolt, remove the two screws holding the black throttle cable/slider assembly to the top and remove the assembly. If you carb still doesn't work after all this it may be time to retire that carb for the weekend and send it off to an expert.Ĭarb Cleaning - Cleaning Comer carb is a simple 10 minute task. Finally, check the internal filter screen on the carb for debris. This is a good item to replace regularly. The float needle can form a ridge after a while (like a month) and stop working correctly. The other common reason that makes a carb not work is a bad float needle. One is your gas cap, is the vent working in it? Sometimes a gas cap vent will lock up essentially locking your fuel supply system so the engine starves of fuel. If these basics are covered and it is acting funny there are a few things to look for. If you have covered these basics then there really isn't much more you can do for the carb. Have it secured - so many people forget to tighten the retaining bolt and the carb falls off.

Jet it properly - we'll discuss this in detail below, but make sure you have an appropriate jet for the conditions.

It is a good idea to take it apart and clean it before every important session like qualifying, heat races and finals.

Keep it clean, there is nothing worse than some debris in the carb affecting performance.

And I will cover all of these things in detail below: You'll read all sorts of internet lore about tilting it one way or another, or spacing it off the engine on the manifold a quarter inch or so, etc. Tuning it consists of changing the jets and that is about it. The basics - The Kid Kart carb made by Dellorto is a very simply float style carb. These basics should significantly improve the tuning you do throughout the weekend so your jetting is perfect for the main event. Kid Kart carbs and tuning tend to be the weakness of most teams.
