Well I've reading and breaking my head trying to figure out what else to do since last week...I'm not sure what else to try so i turned to this forum for some guidance. I've had my Baja for a few years now. Last year I didn't run much until recently that i tried to start it and it wouldn't start so i checked the spark plug against the motor and i wasn't getting anything so i bought a new spark plug and still nothing. Comes out to be the coil that was done so i replaced it and got spark back but still wouldn't start....It felt really rough when puling to start, very jerky...removed plug and it felt smooth. Tipped the car over just to make sure i didn't flood the engine and nothing came out. Put the plug back in and felt hard to the point that the plastic part from the pull start broke so i ordered another one. I replaced it and this time i heated up the engine with a heat gun, it felt better when i pulled but still nothing.....i then heated the engine again and held the throttle open and BANG! it starts with a bunch of white smoke, i held it there to get rid of anything left in the engine but when i let go it slowly turned off. I tried it again holding down the throttle open and it turned on again but as soon as i let go same thing happened! I checked the gas cap to make sure the hole wasn't clogged up so that is good. Before i go into trying to break more things i wanted to see if there were any other suggestions i should try....everything that i did was based out of suggestions from other threads i read, at least i got it going holding down the throttle but if i was to go try to turn it on right now the pull start would be rough and jerky unless i heat it up and then hold down the throttle to get it going. Its a learning experience and a lot of reading after work but I'm not trying to give up yet. pheeewww! thank you to whoever reads or replies to this long thread.
