i got a 185 honda with approximatly 40 hours on a top end rebuild.i finally got it to stop smoking but it still fouls the plug with only an hours run,some times after 2 or3 hours i need a new plug. any ideas?

 

My guess would be that you might be running too rich and fouling out your plugs.

 

the carb center needle is on the 2nd groove from the top,should i go up any further?what else could be done?

 

You could try to put it at the top and see if it runs anybetter or longer but i wouldnt run it extreamly hard cause running it lean could hurt the valves. If it runs good and doesnt foul your plug anymore i would say your good to go.

How did you get it to quit smoking anyways???


What color was the smoke???

 

it just seemed to stop on its own.it still smokes a little,not as bad as it did.

 

Any new news???

 

What color is the smoke???

 

the smoke is a blue gray color,not sure why it stopped,i put the needle on the very top groove and it revs high,cant idle it down with the idle screw,any ideas?

 

well since the smoke is blue that means your burning oil. thats what is fouling your plug out. move the clip back to where it was. Sence you just got it, it probibly smoked before the valve broke if you bore it out like OLDKAWI said it will probibly stop fowling out your plug. or hone it out and get new rings. that should stop the fowling.

 

have worked on many old atc's in the shop. even after cleaning the carb and replacing all internal parts, some machines would still foul plugs. on a couple of machines we replaced the carb w/ a brand new one and had no plug fouling since. not exactly sure whats wrong w/ old carb but a new carb worked. this won't help you though if you are burning oil like your describing but just something we found that worked on a strong motor.
