ok, my scrambler 400 is a 2 stroke model. it was running way too rich on the oil so i had to adjust the oil injection system. the person before me had it adjusted incorrectly and it was just pouring the oil in. well i got it adjusted but now the atv will not run quite right. it wants to stumble when you floor it. takes about 4 seconds before it will kick in. Does anybody know exactly how to adjust this thing. i have been working on it for over an hour and i am getting very frustrated..lol...

Thanks,
Justin

 

update! today i messed with it a little more after adjusting the oil injection system and it backfired and blew the muffler pipe off up close to the motor. i had to put it back on. does anybody have a clue what in the world is wrong. i am at my wits end with it.

 

The pipe and muffler packing are full of oil, clean them out, and repack the muffler, the plug need replacing and the air filter cleaned or replaced.

good luck..................handycap

 

Forgot, also pull cover on thumb throttle and adjust the safety cable break switch. Adjust gap to about 1/8th inch when throttle is closed.
