Re: 1957 Johnson 35 comp test

you best get a manual, before you really mess something up. the blue are the pressure relief valves, the yellow are the bypass for the release compression to get to the exhaust. the relief valves have springs on them and are very rarely the culprit in your problem.

you have been ask several questions in the previous post, with out answers to them, we cannot give you proper advice.

Sorry, I thought I had answered everything. I know F_R asked if the motor ran, I haven't tried to make it run since at this point I do not have a valid fuel source. I have the remote starter hooked up, which I used to do the comp test. What else did I miss?

I know that I need a manual. I am working on getting one, and I did get your link (Thanks TD) for a CD manual.

It seems like I may have PO'd everybody, which was certainly not my intention. I would like to apologize if I have not been clear in my responses or have missed answering something. This is all new to me and I may be a little over-zealous. Please let me know what information you need to advise further.

TD I am not sure what the reference to blue and yellow meant unless you are referring to a diagram in the manual.

I am waiting for a CD repair manual to arrive in the mail. I would like to remove the head in the mean time to see what I am dealing with, as was the suggestion. It looks like I will need to remove the rear lower portion of the power head housing (not sure if I am calling this the right thing) where the cowling attaches in order to gain access to lower head bolts. Is there a best way to do this? Is there anything I should be particularly careful of when doing this? Any special trick to removing the head? Should I just cover the thing with a tarp to avoid the temptation and wait for the manual.:redface:

As always any help is appreciated

i'm reposting pictures since it looks like it disappeared. the areas mark in blue are the pressure relief valves, activated the the rod coming from the flywheel. the area marked in Yellow and the ports that let the release compression in to the exhaust, the compression has to go somewhere.

clik on picture to enlarge.

i would try to get it running before pulling anything. don't get the cart before the horse. clean a the fuel, tank pump it up to make sure it will hold pressure.

wait for your manual. also take pictures as you go along, so you can find where that extra piece or bolt goes. Not being funny.

Okay. I found someone local that may have a good tank but no hoses. I will have to go and see if we can make it work.

Since I can see rust in the bottom of the tanks that came with the motor, are they worth trying to salvage?

Also, the LU drain plug is missing. I assume that I would want to fill 'er back up with gear oil first before really trying to start it. So three questions:
1. Can I borrow a plug from my '71 'rude?
2. Can I use the same Hypoid gear oil?
3. Do I fill the same way, from the bottom drain plug?

Thanks again.
