    Are all the old points coils the same regardless of hp? I'm fairly certain the coil i put in was from a 9.5hp. Obviously the same dimensionally. But would there be any difference in the spark?

    You do? I've always had luck just popping them out and if needed snipping the end of the plug wire and putting it back in. But then again. I've done say 6 of these older Johnson/Evinrudes with the points ignition so I may just be getting lucky. Are those adjustable spark gap testers suitable...

    Yeah I'm familiar with servicing these ignitions. (How to set points, install parts etc). Though when a spark appears good when tested but cuts out when ran I don't have the experience to know what that indicates. But it makes sense those two longer coil screws I always wondered why they were...

    Ohh it is very sketchy haha. It seems to hold up just fine to the power for now. So I'm gonna ride it out till winter then dig into that.

    Okay update time. Pulled the flywheel. Found one of the condenser wires rubbed through along with the wires going into the back of each coil. Replaced the condensers as I have some spares. Same results only really running on one. Tried to inspect the plug wires but I can't for the life of me...

    I'll get some good ones in the daylight tomorrow. It's likey not a 73 going off the ignition not having the coils on the block. It's 69-71 I'm thinking.

    So it seemed to clear up in the tank. So I ran it this evening out on the lake and it was doing well pushing my 14ft Crosby sled with 470lbs of people in it up to 19-20mph. Getting on plane easily. Then after a few runs it was dropping out that cylinder periodically then towards the end it...

    Started with cleaning the carburetor. Replace some crappy looking lines. And it'll start and run in a bucket fairly decent. You still occasionally here the 1 cylinder dropping out. I fired it up on each cylinder independently and it does run on both independently however the top cylinder...

    Yeah that's 100% my bad I expected it to be on the end of the jet. It was on the side I was covering it with my fingers the whole time. I'm fairly confident the heads never been changed. Just kind of going off context clues but paint matches perfectly there's no signs it's ever been off. I...

    I'll end up pulling the flywheel. Someone changed both plug wires so connection to the coil is definitely suspect

    Recently picked up a 1969-1972 18-25hp engine (still nailing down the specifics). But for sake or discussion we'll assume 18hp. I got a bit to mess with it after work. Seller said good compression and spark. Compression is good and even. And it did indeed have spark on both cylinders. It did...

    Took the carb off. and I see the main jet but theres no numbers on it indicating size. Am I looking for something in particular?

    18 or 25? Anyway to tell?

    There is the plug but it's all banged up? Like it was replaced and hammered in very poorly. Can't read anything on it. So what would I be looking for jet wise?

    18 or 25? Anyway to tell?

    I didn't think of that good idea. And I'll take some when Im home from work today. Photos of the power head? I know it's got the bigger carb that started in 68-69? (Going off parts diagrams) But still has the coils on the timing plate. So pre 73?

    18 or 25? Anyway to tell?

    So I recently acquired an old evirude. Supposedly a 25hp. The transom tag would indicate a 73 25hp. However the cowling is definitely the 60s-71 cowl. Not the square style of a 73. The welch plug is jacked up and illegible. So either it's a 73 with earlier cowling. Or an earlier motor with...
