Re: Boat complete Restoration

Hello recelect! Looks like you are doing some headway. The water pump impeller is a big issue. Do not run that motor again until your pump is fixed. I hope you had enough of it left to cool the motor when you test it earlier. Since the compression on #4 went up it kinda tells me that you had a stuck ring. There are several reasons for a ring to be stuck, some not too bads and some soon to be bad. Hopefully those rings was just gummed up.
Once you fix your water pump then you can fire it up again. You can probably work on that trailer and get the boat in the water even if it is not finished forf a quick test drive. The motor can behave way different under pressure than when you have it on muff or a barrel full of water. BTW, when you have your motor in muff or in a barrel full of water avoid reving the motor. Although you might be able to get away with the occasional rev you can end up doing some damage to your motor. Best off is to take someone along with you to the lake and let them drive, in a day with little traffic, while you do any adjustment or measurement that requires reving your motor for a period of time.
Some pictures from the project would be nice...

Good luck!

Re: Update on Carb and motor

Re: Update on Carb and motor

So, If anyone has been reading this thread, then you know I was in desperate need of a new carb Power piston that I could not find, or another carb. I was also advised to get the motor going before I do anything else, so that is what I spent the weekend doing. mind you, here is colorado on friday and saturday it was near 70 degrees out, which was awesome to work in, then today, the day that I am ready to fire her up, it is 30 degrees, snowing, and the wind is ripping roofs off buildings.... But, being the impatient guy that I am I braved the weather to get her up and running!

so with that; last week I took a chance and ordered a carb off ebay. It cost me 30 bucks but I already had a carb kit and really did not want to buy a new carb. It arrived yesterday, saturday, and I spent sunday morning re-building the thing. Now the "new" carb was close, but not quite the same thing. there was suttle differences between my carb and this new one that made putting the throttle linkages together a tad difficult. I was planing on using the best peices off the 2 different carbs to make 1 awsome carb, but I found that the only peice I could use off my carb was the top section. This was allright, except when I went to put the carb on the motor, the throttle linkage on the new carb was different and would not clear the intake.
But, this did not stop me. I just happen to have an incredibly handy cordless cutoff tool that made quick work of cutting the linkage to fit. once I did that, She bolted right on!

Next was hooking everything else up, fuel, choke wires, pcv, etc... and then to try to fire it up. I cranked and cranked, and cranked to no avail. Opened the fuel filter up, spewed alittle fuel out, closed it, dumped alittle fuel into the top of the card, cranked, and she fired like she was new. I am not going to lie, I was pretty excited. The first time I started this motor it ran like crap, after I found the carb was in such bad shape, I new I would have to re-build it, which I have never done before... to say the least, I figured I would have to find something I did wrong during the re-build and start over... but I was lucky. she fired, the choke opened and she came to a nice steady idle. I "floored" it and with no hisitation at all she reved up in RPMs. I am just really impressed that it ran so well.
I also figured there would be alot of black smoke but there was hardley any, especially after she warmed up a bit. There is no doubt that this motor is good and the rest of the refurb can continue! Next is paint! soon as I get new paint on her, I will post more pictures!

If you put enough pressure from the pump to fill the bowl, and still needed to pour gas in it; the passage from the bowl to the accelerator pump may be still clogged. Or not primed yet.

Re: Boat complete Restoration

Connect a vacuum gauge up to a running engine should be steady at idle. I'm sure theres a web site that will show the different "Interpretation" that can be made.
You'll get more info over in the engine forum.

That is not the test i was talking about. I got my terminology wrong, I meant a leakdown test. Dont ask me how I mistake it by the vacuum test... This is the test I am talking about:

Sorry for the misinformation, hiding under a rock now....
