Hi Grinder<br /><br />Just for testing, try to swap the output wire from powerpack between coils two and three and see if the problem follows coils. Cranck the engine with sparkplugs attached, but not in, grounded to block. If # 3 still misses, the new # 3 coil is badly grounded or the coil itself is bad. If # 2 now refuses to fire, there is an error in the new pack.

Grinder, G-Dane has good advice for checking spark problem.What is year model of 65hp?

Re: 65 hp evinrude

Thanks it's a 72 and has been a good motor started having problems all at once. I'll try that and let you know what happens.

Re: 65 hp evinrude

found out that the ground wasn't hooked up! hit the switch and it fired up. shut it down and went and hooked up the muffs, now only hits on 1 cylinder. I'm glad I'm already bald, checked the fire good spark on all 3. could it be the carbs? the original trouble started out not picking up speed. I ran it without the covers and it appeared to be getting gas in all 3 carbs thats when I was told to change the pack and coils. I would like to thank you guys for your help.

Re: 65 hp evinrude

Grinder<br /><br />I learned, when I work on these things ( and especially when something is new to mee, to be very carefull. First check if all components that should be grounded, are. It includes stator, power pack, and coils. Take a good look at everything. Then check the wiring, are all assembled carefully. Pull the connectors apart and press togetheragain a couple of times to get good connection. A trick when troubleshooting ignition is to save some old plugs to test with, grounded to block, instead of unscrewing and tightening the motors plugs, using time and wearing threads. Are you sure it is not running out of gas now, or you forgot to loosen tank air screw, if it has one. Check with a couple of spark plugs and see if it sparks.

Re: 65 hp evinrude

Sorry, someway or another i didnt get your entire message in the first hit. Yes - sounds like its not getting the fuel it needs now. I guess it is visible on the plugs too.<br /><br />If you squirt a bit of fuel in all carbs and try to start, you will see if if starts for some seconds on all, its a fuel problem

Re: 65 hp evinrude

Ok I'll do that but it may take me a little time to get back to you. it's raining cats and dogs here. I'm kinda of suspicous of the carbs. I pulled the drain plugs and looked in side. the high speed orafices are buggered up where someone has tried to take them out. I have a jet removel tool but it ain't gonna work on those. can they be removed with a easy-out or will i have to take them to a machine shop? I hooked a spark indicater and it has good spark on all 3. I keep thinking fire, gas, air and timing.

Re: 65 hp evinrude

Maybe you won't have to remove the orfices. Try a tip cleaner or just blowing them out with compressed air.<br /><br />c/6<br /><br />Hooty

Re: 65 hp evinrude

thanks guys, I'll try that Hooty and let you know what happens. MERRY CHRISTMAS All

Re: 65 hp evinrude

Oh boy, I just did a compression check on this thing and I got 127lbs. on #1 and 130 on #2 and 85 on #3. tell me something good. Roy

Re: 65 hp evinrude

grinder, remove the sparkplug on the cylinder with low compression and inject a small amount of two cycle oil .Rotate the flywheel by hand a few strokes to distribute and run the compression test again.If the compression increases one of two problems exist.Either the cylinder is carboned enough that the rings are stuck back in their grooves or the cylinder and or rings are wore out possibly due to lean mixture.If there is no effect on compression after oiling cylinder the piston may be fractured or the head gasket has failed.
