Re: Johnny not starting up cold and dies when idle....

GL....have you checked the spark on the engine lately? Each spark should jump at least a 7/16" gap with a hot white spark. And what plugs are you running? I believe a QL77JC4 (Champion) is the recommended plug. Book says to gap them at .030 but you can get a better idle at .040.<br /><br />Yeah....questions may be "left field". But....humor me.)

What about the float levels in the carbs? If the floats are set to low ~~~ you know!<br />I do not know your engine, does it have four carbs? If so check the carb for the dry cylander.

Re: Johnny not starting up cold and dies when idle....

hey guys, thanks for all the advise on the motor. it really helped a lot. seems that doing everything everybody told me was good for the engine but it turned out to be the battery and the throttle cable. bought me a switch and put in a second battery and started the motor up with both batteries and she turned over and i adjusted the throttle cables a lil bit more and it did the trick. and for cylender 1 not being moist. i still havent found out what going on with that. but she fires. i think this motors ready to retire. she's pretty much way past her prime so imma use her for a few more months and scrap it. cause i dont think i or anybody else should even put this much effort into trying to fix it. i guess i'll just use this boat at the lake and grady white for the gulf. i'll keep you guys posted on when imma scrap this motor. thanks a lot guys.

Well.....at least ya' got it to run. Thanks for lettin' us know what happened. These engines are good engines and can be made to run well with a little effort. If the compression is still good....it might be worth that little effort to get her going.
