On my 360 when I hit the throttle there is a hesitation like it chokes itself off for a split second before there is any response,can this be fixed by carb ajustment ? would that be an indication of being to rich or to lean and which way do I adjust the screws ? Thanks for the help !!

 

Turn the mixture screw in (while hot) until engine slows down. Then turn it out until the idle is fastest. Turn the screw 1/4 turn past the first point of fastest idle.

Make sure your air filter is clean and nothing is clogging or nesting in the airbox inlet. If it still hesitates, the needle is rich or lean. If it is lean it will cough a lot when cold then cough less when hot. If it is rich it will run fine cold and bog when the engine is hot.

You can richen the needle by putting small washers on it to space it back out from the bore (try .020 to .040 worth of shims). If it is too rich, I think you would have to change the pilot jet to lean it out some. Maybe you could get a leaner needle, I'm not sure. Or do some engine mods to get more power then you woulndn't need to lean it down.

 

I'll give that a try first , I am assumeing you're talking about the air pilot screw ? Also forgot to mention that I did clean the air filter changed all fluids and put new plug in and evrything is still stock no mods.

 

The best name for that screw is idle mixture, although pilot screw is understandable. It cannot be called "air screw" on this type or carb because it is not an air screw. We have already bashed each other up about this on another topic.

Another reason that the 360 hesitates is due to hot is fuel boiling in the carb. It has been solved with a heat patch on the bottom of the tank, and/or heat wrap on the muffler, and or heat wrap on the fuel line. That is what they tell me anyway. There isn't a lot of room in there, so do the best you can.
