These bikes are notorious for balancing problems to do this takes vacuum guages connected to both carbs. the service manual shows how to accomplish this task. The hard thing to find are the brass adapters for the right bike. Once you have the tools everything else is fairly easy.The key to this is read the manual. This system is dependent on carb balancing and will not run right if this is not accomplished

If your plugs are light brown then your fuel mixture is perfect.

But you may have clogged idle jets due to having the bike sitting for a long time without STABIL in the gasoline, may also be clogged fuel screens or filter.

I have a kvf360a quad bike it is very hard to start and when i can get it running it is ok untill you stop, then it die's


First check your spark plug to see if it's not super dirty or melted, if it looks ok(brownish to light grey) it is most likely the idle jet in the carburetor is dirty. Your carb uses different jets for different things, starting, idling or riding. if one becomes dirty that activity becomes difficult. But if one jet is dirty, most likely the others are getting that way too. Have your carb cleaned or do it yourself if you have the ability and then change your fuel filter as well, since it's letting stuff get into your carb. Hope this helps.

Spluttering on sett off but ok at top end


on general principal probably lean low end. solutions could be...larger low end jet, carb adjust, better exhaust, slight timing advance, etc.
Start with timing and be sure that's perfect (including plug gap), be sure exhaust is in good condition with all baffles and mufflers in place and no major leaks, then adjust carb..

The is spluttering there is no adjustment on the carb. The spark plug and air filter are ok. Just before it runs out of petrol it starts to run normally


The carb is flooding, as it runs out of fuel it leans of and runs normally, get the carb pressure tested, or just replace the inlet needle under the metering diaphram, and try again.

Pouland chain saw won't start, seems to not be getting spark


1) How have you determined that there is no spark?
2) Have you used a type of spark tester?
3) What is the condition of the plug. Brown or dark brown is OK. Black or silver is NOT Ok.
*If you do not have a spark tester,
a) remove the plug, and with it connected to the wire,
b) find a portion of metal around the cylinder that you can ground it on, and then pull the rope.
c) If the plug is black, you may see spark, but you should replace the plug.

*** PLEASE NOTE ; if there is excess fuel in the cylinder or on spark plug,
it can catch fire, so be carefull to cover the hole with a heavy rag so that any fuel
cannot be exposed to spark plug durning test !!!!
Get back with me on how this issue works out.
thanks, rwvanlue
Basics to check:
1) Spark plug - brown or dark brown - OK
a) is it carbon or fuel fouled
b) is there spark

2) Muffler remove for inspection
a) exhaust screen clean or plugged
b) inspect cylinder wall/piston as the flywheel is slowly rotated
3) Check cylinder compression


Fuel starvation - 'lean fuel' condition
Basic things to check:
1) spark plug
2) spark arrestor in muffler
3) fuel lines and tank filter
4) turn adjustment needles out (counterclockwise) 1/4 to 1/2 turn
Chain Saws:
5) check impulse tube and intake boot for cracks or leaks
*if all of the above are OK and/or do not improve performance then:
Remove Carburetor
6) replace gaskets/diaphragms
a) use a spray carb cleaner to clean jets, holes, and body of carb
b) fuel pump diaphragm goes against the carb body,
then the gasket towards the outside
c) metering gasket goes against the carb body,
and the diaphragm goes towards the outside

Bike travells well until 6-7ooo revs it starts to splutter


Hi and welcome to FixYa,

Your description indicates that most likely the carbs are getting too much air. This could be verified if the sparkplugs have light brown to dirty white burn colors on the tips, a sign of a lean mix; too little fuel, too much air.

It could also be caused if the original airbox was replaced with open breathers such as most models of K & N or a leaking air box enclosure.

Good luck and thank you for asking FixYa.

Readjust the carbs.The bike has lean mixture (too much air).Check your spark plug's electrode color.It must be dark brown.Neither black nor white.
