hmm is the smoke coming out of your pipe white?. and are you running a stock main jet if not what size is in there now?.

 

[PUDDKILLER]

yes ron iit smokes white alittle. its a stock jet. and its new gas. when it ran good. i took it out to the woods and it ran fine for 5 hr. then it started fouling the plug in like 20min. i put a new plug in it ran good for 10min then started bogging like it does. i had no air box lid and it was vary dusty that day. i check the reeds they are good .but now i put a new plug in it still bogging down

 

[03blasteryfs03]

what color was the plug

 

[ron89]

ok it sounds like its burnin gear oil that could cause it to foul plugs.

 

[PUDDKILLER]

sorry i havent pulled it yet. but i will right now

 

[PUDDKILLER]

what do you mean ( its burnin gear oil)???

 

[ron89]

your crank seal could be leaking or leaking from the 2 case halfs, and its getting into your crank case and its getting mixed in with your gas/oil and getting burned up.

 

[ruthless_one3k]

could be an air leak, the pilot jet clogged or maybe the float level is too low

Is the tors still on the carb?

 

[PUDDKILLER]

this is a new plug just ran it for 15min.

 

[PUDDKILLER]

just put a new stock jet, carb rebuild kit. yes the tors is still on the carb. remember it ran fine for alittle bit. and then started doing this.

i just had to ask this since you said it was dusty that day. did u try cleaning the air filter??? maybe its not getting enough air cuz its clogged???

i think i did..lol i took it out and cleaned it but you know its always 420 around here. maybe i didnt clean it good. ill try taking it off. and dude there was alot of dust. so if the dust got in the motor. what parts do you think it effected? it scare me to think some oil is in my caseing . when i put the piston in i saw some dark oil was in the case. but my gear oil is clear oil. so you think the was the 2 stroke oil ?

We are having the same problem right now out of a built 240 blaster it will start but as soon as you touch the throttle it kills it. Check your spark it needs to be a thick blue spark. Ours had a light blue spark it had just enough spark to start then it kills it when you touch the gas because it doesn't have enough spark to burn the gas so we had to order a new coil. If you got a friend with a blaster try switching out the coils and see if that is it.

[blasterboy805]

could be a crank seal leak clean yor carb and jets put race gas in it and it sonds like my blaster when its ot of gas or the jets are plugged

 

[ckjohneh]

im gonna say crank seal or carb problem. you may need to bump up a main jet size.

 

[PUDDKILLER]

ok it was the tors. i unplug the dam thing and it revs up. but i can hear a little tapping in the lower end of the motor.
