Left cyl. spark but no fire!

[Devildog 8994]

My question, yesterday was screwing around in the woods, after about 20 min. left cyl started cutting in and out only one time. blipped throttle cleaned out!

NO PROBLEM !!!!!!!!!!!!!!!!!!!!!!!!!

This morning its only running on one cyl if you let the rpm die down it dies!!!!!!!!

MY left cyl is dead unhooked tors,checked spark,plug was damp when I pulled it.

I have spark with or without tors hooked up. The right cyl is running ok but it will bogg down and die. I pressume it because left cyl issue! BR8 plugs, 36 to 1 ratio mix,air filter clean.

 

Is this a good enough reason to pull the motor and send it off for a major overhaul? Porting, bigger carbs,upgrade the clutch! and some other tweaks?

I have owned it about 4 months it is a kick!!!!

 

 

99 T-5 pipes,pro design impellar,K&N filter,LSR Axle I have been replacing the things it needs for better reliability, axle,impellar,chain and guides,carrier bearings, needs a-arm bushings,new plastic,would like to put new radiator but the factory doesnt leak yet. any input would be appriciated!!!!!!!!!!!!!!!!!

 

Thanks,

run a compression check and get back with us. may have a hole in your piston.

Checked compression 145 LEFT 143 RIGHT seems to be alright to me I am going back out to the garage for some more fun. I will check back later. see if you guys have other suggestions~!!!!!!!

you may also have a cracked/deformed reed. this owuld cause the air to flow out of the intake port and back through the carb; where it should be going up through the transfers and into the combustion chamber.
