Author Message   kevin tueken Member Username: tuetken Post Number: 5 Registered: 10-2007 Posted on Saturday, May 10, 2008 - 03:08 pm:    Hello, I have a 1973 Evinrude 2hp, model 2302, that I got from my grandfather. I am looking for what size spark plug it uses, as for the one in it has been missed place and I never wrote the size down. Also, what is the ratio for gas:oil that I should I run in it? Thank you!   Joe Reeves Senior Member Username: joereeves Post Number: 5993 Registered: 02-2001 Posted on Saturday, May 10, 2008 - 05:26 pm:    Mixture is 50/1. Spark plug is Champion J6C with gap[ set to .030 .

Top slow speed = seat gently, then open 1-1/2 turns. Setting the high and low needle valves properly: NOTE: For engines that DO NOT have a shift selection, obviously there is no NEUTRAL position. Simply lower the rpms to the lowest setting to obtain the low speed needle valve adjustment. (High Speed) Start engine (it will run pretty rough), shift into forward gear, take up to full throttle. In segments of 1/8 turn, waiting for the engine to respond between turns, start turning in the bottom high speed needle valve. You'll reach a point whereas the engine will either start to die out or spit back (sounds like a mild backfire). At that point, back out the needle valve 1/4 turn. Within that 1/4 turn, you'll find the smoothest setting. (Low Speed) Slow the engine down to where it just stays running. Shift into neutral. Again in segments of 1/8 turns, start to turn the top needle valve in. Wait a few seconds for the engine to respond. As you turn the valve in, the rpms will increase. Lower the rpms again to where the engine will just stay running. Eventually you'll hit the point where the engine wants to die out or it will spit back. Again, at that point, back out the valve 1/4 turn. Within that 1/4 turn, you'll find the smoothest slow speed setting. When you have finished the above adjustments, you will have no reason to move them again unless the carburetor fouls/gums up from sitting, in which case you would be required to remove, clean, and rebuild the carburetor anyway. Kevin this is info I found on the web that helped me get my new(to me)2 HP running good.Hope this helps.   Joe Reeves Senior Member Username: joereeves Post Number: 5997 Registered: 02-2001 Posted on Saturday, May 10, 2008 - 10:25 pm:    If you're going to quote one of my personal listings, list the complete article as follows. Do not plagiarize as, to put it mildly, that practice is somewhat frowned upon! (Carburetor Adjustment - Single S/S Adjustable Needle Valve) (J. Reeves) Initial setting is: Slow speed = seat gently, then open 1-1/2 turns. Start engine and set the rpms to where it just stays running. In segments of 1/8 turns, start to turn the S/S needle valve in. Wait a few seconds for the engine to respond. As you turn the valve in, the rpms will increase. Lower the rpms again to where the engine will just stay running. Eventually you'll hit the point where the engine wants to die out or it will spit back (sounds like a mild backfire). At that point, back out the valve 1/4 turn. Within that 1/4 turn, you'll find the smoothest slow speed setting. Note 1: As a final double check setting of the slow speed valve(s), if the engine has more than one carburetor, do not attempt to gradually adjust all of the valves/carburetors at the same time. Do one at a time until you hit the above response (die out or spit back), then go on to the next valve/carburetor. It may be necessary to back out "all" of the slow speed adjustable needle valves 1/8 turn before doing this final adjustment due to the fact that one of the valves might be initially set ever so slightly lean. Note 2: If the engine should be a three (3) cylinder engine with three (3) carburetors, start the adjustment sequence with the center carburetor. When you have finished the above adjustment, you will have no reason to move them again unless the carburetor fouls/gums up from sitting, in which case you would be required to remove, clean, and rebuild the carburetor anyway.   Larry Jones Member Username: nowgrn4 Post Number: 12 Registered: 05-2008 Posted on Sunday, May 11, 2008 - 10:08 am:    Sorry Joe.I did not attempt to plagiarize or claim I was the author of this non-copyrighted materal.I said I found it on the web somewhere and was trying to be helpful.It's none the less, A very well written explanation.I'm sure it's not the first time nor will it be the last that your wealth of knowledge is shared on the"Information Highway".
