Hello all

Well i finally managed to solve the problem...i've had two full tanks so far with no problem...apparently the gases from the engine where returning to the tank instead of going out through the pipe..that's the reason why the tahk lid popped -up...it was a pressure build up. I found this because jut as a test i tried to turn on the engine with the lid of the tank open..and it worked...from there the solution was obvious.

It turned out to be the exhaust..but it was something strange...i ust took it out and checked that tha air could move around easy...and it turned out taht it was ahrd to get air trough the exhaust holes....i thought that was the problem but after cleaning and injecting compresed air to the pipe o ended with the same problem..but anyway..i installed the pipe again and then everything worked ok...

I mean..i don't recall taking out anything that plugged the exhaust..i didn't see any dirt or something similar that could cause the problem..and the air was flowing around exactly in the same way as before..apparently just taking out the pipe and installing it again solved the problem..kind of strange...but it worked...


Thanks for all your help. Hope this thred can help some other guys with the same problem..

By the way...i'm loving the magnum...great power.....very easy to start now that the problem is solved...it alwasy starts at the first try...the motor does not stalls and everything seems just fine...i'll keep testing for some tanks to see if everything's ok.

thanks to all

PD : Great support fro CEN. Thanks
