    I pulled off my intake manifold and it looks good as far as i can tell. I've inspected the leafs and they all look good, Everything is real clean and I found no pieces of junk in there or broken parts. I did notice an interesting issue in the lower port section (bottom most portion of the...

    1975 135HP Stator and Timer Base

    Okay, I pulled the Flywheel off last night without a hitch. (But I admit when that thing went "POP!!!!!", I thought I snapped something:eek: Everything looks okay underneath so far. What are some things to look for? I want to make sure everything is correct underneath since my timing is an...

    1975 135HP intake manifold bolts

    This is one of those, "how the %$!$ did I miss" this categories. Please look at the attached photo. I just realized that I have a bolt missing on my intake manifold. Right where I put the red dot. To the starboard, there is the timing pointer. To the port, a screw. Is this supposed to have...

    Two top carbs

    In a different post, a comment was made regarding top and bottom carbs being different on a 1975 135HP. The comment was in reference to the throttle WOT stop and that the bottom carb did not have one. So I looked at mine and they appear to be exactly the same carb bodies. By having a stop, are...

    1975 135HP will not idle less than 1100rpm

    I've been working on this engine off-and-on for a few years now and it just won't give me 100%. Seems to work great on the high end but just does not want to run at low rpm. Here are my current standings Just rebuilt both carbs, even added new orifices (all eight). Carbs looked great when I...

    Fuel Connector on Motor - 1975 135HP

    Does the Fuel Connector on the motor cover have a check valve? When I unplug my fuel line from the motor, some fuel comes out this line. Not a lot but at least what's in the line between the connector and the fuel pump. If there is a check valve, and it is not working, will there be any...

    1975 135HP Johnson Carb question

    I was rebuilding my carbs for the first time yesterday (Let the 'pros' do it up until now) and found something unusual. On one of the carbs, when I popped a core plug out, I noticed a gash in the bottom of the well. It looked like someone popped out the core plug with a screwdriver and left a...

    1977 25HP Evinrude temperature

    A friend was telling me that his tell-tale is sometimes cold and sometimes too hot (to the point that he is careful about just sticking his hand in the stream to check temp). That didn't sound right to me. I asked him if he'd checked the thermostat and his reply was that he didn't think that...

    Idle rpm on 1975 185HP

    An update on my engine. I took my boat back to the mechanic that performed a tune-up and carb job back in March to have him make sure everything he did was fine. He checked the timing, link-n-sync, and all and said everything is great but he raised the idle up a bit. The problem I have been...

    Electrical Component Bracket Mounting

    1975 135HP Johnson I have a question about how the Electrical Components Bracket mounts on to the engine. Mine is such a mess with different sized bolts extra washers here and some missing ones there. As well as an ill-fitting grommet that is really messed up. I bought new grommets and then...

    Fuel coming out carb throat

    1975 135HP Johnson Performing my link-n-sync after replacing some of the linkage and this time I had the silencer off. I noticed fuel collecting on the bottom of the carb throat in front of the choke plates. Not a lot but enough to be the culprit of my continual puddle of fuel under the carbs...

    1975 135HP Johnson Carb Linkage

    I received my box of new parts today ordered from BRP. Mostly linkage pieces for the carbs to replace those that seemed worn out or wrong. I have a question regarding the throttle-to-choke linkage. Looking at the photo of my carbs, you will see that the throttle and choke linkages are...

    1975 135HP WOT RPMs

    I have done all I can do for now with my motor and this is the final assesment. I got her out on the water yesterday. She still will not idle at less than 1100 rpm. After replacing the rectifier my tach read higher values and I believe they are correct based on my my latest tests. In my 1973...

    Right carb for 1975 135 HP Johnson

    It has been brought to my attention that I may have the wrong carbs on my engine. How can I confirm exactly what carbs on are this engine? Since the stern mount had a different ID (73 85HP) it is possible that I could have carbs from an 85HP on this engine. Is there a difference between...

    Bad Rectifier and Tach response

    1975 135HP Johnson Last night, I found out I had a bad rectifier. There was no voltage change between engine off and a high idle as read across the battery. I ran through the rectifier test procedure comparing forward and reverse voltage passing over each diode (Y-Gnd, Y/G-Gnd, Y-Red, Y/G-Red)...

    Grey Spark Plug Scum

    1975 135HP Johnson I pulled the plugs today and notice some odd coloration on two. The plug from cylinder 2 (top port) was coated with a thin layer of a wet silvery-grey scum. Plug 3 (bottom star) had some too. But the other two plugs were just wet. I am still going through all the...

    Other, other side of the coin opinion needed

    1975 135HP Johnson Well I finally got the boat in water and ran it for a real test. Started relatively well (Only three tries!!!!) and would idle with the motor submerged. Idle rpm was just under 700 while in neutral, when I put it just in gear the rpm's would drop to about 400-500 and the...
