    Fuel delivery diagnosis question

    I have a 1971 1150 inline 6. Ran good 6 months ago but the other day I had a hard time cranking the motor. I have clear fuel line going between the carbs. I finally got it cranked and it back fired and sputtered indicating misfires one 1 or 2 cylinders I'm sure. I noticed the top carb wasn't...

    Trouble syncing a 1969 6hp Johnson

    I only have the serial number of this motor so I'm guessing the year here. Looks like late 60's early 70's tho. The specs say it needs to be on the starboard side of the cam follower when the throttle shaft begins to move. However, It seems that the cam follower is before the mark when the...

    Pressure testing for water in cylinders?

    I previously had a water leak. Pulled the covers and replaced with new gasket. Fired up in the driveway and no water out the exhaust. Took it to the lake for a test drive and it did good. I had no trouble hitting wot and it idled well also. No lag or sign it was bogging. I checked the plugs and...

    Choke wiring question

    The choke was removed from my 1971 115 when I bought it. I'm planning on adding the choke now and need a solenoid to go before the choke solenoid. I have the choke solenoid and was wondering what the disadvantage would be to hook the choke solenoid up to the starter solenoid so that when you...

    throttle cable slack question

    without moving the shifter, I can move the throttle linkage 3/8". There's so much play that at WOT, the second carb pickup is just hitting. It's completely missing the top end of the throttle. Can the cables be adjusted to fix this? I've searched this issue but came up with nothing that...

    '71 1150 dies when cowling is on

    1971 1150, while on muffs, idles fine with cowling off. When you put the cowling on and idle her up, she sputters and dies. Lakes are so low here right now I can't put in to do idle adjustments in gear. I opened up a little at a time til I hit half turn more on each carb. Does better but still...

    Haha funny question

    So when I was putting the water jacket back on, getting in a hurry, I dropped a bolt and of course it goes down the exhaust tube lol. I remember there wasn't much of anything that blocks the bolt from going into the L/U, so that's where i know it is. Is it a big deal to leave it or will it cause...

    Symptoms of water jacket leak?

    I rebuilt my 1150 and cleaned all the surfaces very well. I used gasket sealer with new gaskets on all covers. I found a few bolts on the exhaust plate and cylinder block cover trickling water which I'm not too worried about. I'll torque those in and see what happens. However, I am worried that...

    Re: Just some pics of my '71 1150 I6 Rebuild. If a picture is worth a thousand words I'm especially proud of this modification. As I was trying to get the retainer ring loose from the badly corroded exhaust plate, the whole piece broke off. So I drilled the hole bigger to accept a 1/2 - 3/8...

    Re: Just some pics of my '71 1150 I6 Rebuild. If a picture is worth a thousand words This is how you tighten 1 of the nuts on the rod bolt. You can access it thru the transfer port. Don't tighten all the way, just snug, then rotate crankshaft to access the other side. Be careful not to...

    I've been told before by some that you can't insert pistons before attaching to crankshaft. Baloney, and here's proof. 1. picture of 4 pistons attached to the crankshaft. 2. picture of #1 piston connecting rod before cage bearings. 3. picture of half cage bearings assembled. 4. picture of...
