More XR250 Problems!!

Hello again

i posted a thread not too long ago about some problems i was having with my xr. after much effort the problems were never rectified.

ever since i had taken the carb off cleaned it and put it back in there was an air leak. you could hear this when kicking it over and running. it cause the bike to cough, splutter and backfire and low revs and stall when idling.

i took the carb off and put it back on four times to try and sort out the seal. i even sealed it with heat proof silicon the makesure it was airtight. to my dissapoint the same a leak sound was there.

although it was not running at its best, it still went so i didnt hesitate to stop riding. one day i took it for a play in these swamp and when riding up a mountain. then rode it down a road. the bike was running bad as if the choke was on, loss of power and spluttering.

after that i took it home and it wouldnt start again. i checked the spark plug, it was black and smelt of fuel. i tried a new plug but no spark. there is power being generated from the engine because i checked it with a multi meter.

any suggestions guys? i am only at home for another three weeks and all i have to do is ride so i am very bored and frustrated at the moment. it is killing mewithout my bike running on these nice days!

cheers in advance

Thanks for your replys.

Do you think timing and valve adjustments would fix the problem of no spark? How do i check the timing chain and compression?

Cheers

thankyou very much Ol'89r, this should help me a lot.
