ok buddy of mine got two mercury disstion da-211 neither runs . so he asked me to try to get them running, im like not a problem im always fixing peoples engines and I love it.
I start working on one n it has no spark long story short replace the coils, condensers , points , spark plug wires , new plugs champion j 6c then went to j8c. even swaped out the magnetic rotor from the other saw, cleaned the hell out the carb and saw itself. cylinders have 120/125 psi also. now I got spark in both cylinders but after I get it running ( which is a freakin nightmare) It will only run on one cylinder and it doesn't matter which one . after it gets hot I will let it stall then put the hot plug into the cold cylinder and the cold plug into the hot cylinder . when I restart it the cold cyl with the hot plug will run !!!!!!! n not the hot cyl with the cold plug BUT if I run it for a while like 5 min or more the other cylinder will start to kick sputter and eventually run absolutely fine !!! now the motor is hot both cylinders r firing she s idling perfectly and sounds like a ported snowmobile lol. I have my carb adjustment screw out about 2 1/2 turns ( which seem way lean to me cause the other saw I did not tough the carb is set at 3 3/4 out ) im running a synthetic oil at 32:1 ( no load on the saw the bar and chain r off just the trans is on) . now when I turn it off and let it cool and go to restart it I go through the same crap all over again it will only run on one cylinder till the motor gets ho then the other cylinder will eventually kick sputter and final catch on and all is well. the longer I let it cool the longer it takes for it to eventually run on both cylinders !!!!! im am completely stumped !!! I don't believe that this is normal cause when its sit overnight its a nightmare to start the next day ( like 20 min of pulling) my last hope is that maybe the needle n seat are leaking causing it to flood out ????
any I mean any advice would help !! unless this is how theses saws run
thanks for any ideas !
