Re: The beast comes to life!!!!

Fatty, Most fuel pumps have a couple of check valves to keep the fuel moving to the carbs. I did not like the fact that your site glass (or sediment bowl) kept going nearly empty.

The reason I suspect it is running on two cylinders is from the sound and the lack of churning of the water in the barrell. You can put her in gear at idle speed w/o issue, as long as prop has clearance. Revving her up in gear will empty the barrell very quickly.

Should the water churn even in neutral? I don't like the empty bowl either. Do you think the motor in this video is running on 2 cylinders as well? I don't see much churning there either. I hope mine looks better that his. LOL!!

big motor and full throttle in a water barrel w prop is a sight to see...and run from but...you could just take off the prop.

Re: The beast comes to life!!!!

Well, it is hard to tell how much churning is going on from the video, due to the angle of the camera, and since the motor runs so poorly. If I remember correctly the exhaust on my Fattys used to churn the water up. In your video, you can see the exhaust passage clearly. I never remember being able to see that, on my motors, due to the churning.

You could do a cylinder drop test to verify its running on all four, if its not hook a timing light to each wire and see if your getting consistent flashes.

Ok. Well here's part of the problem, besides the cracked primer bulb. This little 2 cent part...you've heard it all before! Where can I get one of these???

Got it, thanks! Does the little fuel filter screen bag just pull off straight down? I want to clean it out before the bowl and gasket go back on.

Yes, the screen bag just sits on the pump, supported by the glass bowl. A fuel pump kit will have a replacement for it.

Re: The beast comes to life!!!!

Ok, I have everything I need to give it another test run in the garbage can this Saturday. I will post video to youtube as soon as possible to show the engine running with improvements made since the last video. A cork gasket in the fuel bowl may be better than the rubber one, but we'll see....stay tuned

Re: The beast comes to life!!!!

Just so you kow, My Fatty would ofter start on two cylinders. After running a while or if I reved it up a bit, you would hear the other cylinders kick in. You have both sets of points clean and set properly, right? The second timing mark, between the distributor pully and the block was rubbed off on my motor...hardly visible.

Re: The beast comes to life!!!!

That is interesting Chris. I haven't even looked at those components yet. I saw the engine running before I got it and it ran well, so I figured I could bring it back to this stage easily, but of course it may have been out of adjustment then too. I realize that. In the back of my mind I always knew there would be the time where I got to this point (excuse the pun) so I'll research the gaps and check and see their condition on Friday evening. Timing marks and positions of the flywheel while adusting gaps is needed information. Is that in the sticky's?

Re: The beast comes to life!!!!

Not sure what is in the stickys. Proper way to time the beast is as follows. Turn flywheel until timing mark on pull starter and block align with mark on flywheel. Remove distributor pully cover. Adjust throttle until timing mark on distributor pully base aligns with punch mark on black pulley support bracket. Timing mark on distributor pulley should align with timing mark on pully base. Adjust rod that opens carb to just touch carb roller. Points should be clean and gapped to .020. Now rotate flywheel 90*, and second set of points will be exposed. Look for another timing mark that matches distributor pully, and align them. Points should be clean and set to .020. That it. You may use a ohmmeter to set point oening time (as timig marks match, circuit should open), if you like.

Re: The beast comes to life!!!!

Chris,
Wow, cool. It looks like I may actually be able to do this procedure. You made it sound fairly easy. I'm not a mechanic by trade, but I am smart enough to follow your direction. THANK YOU SIR! By the time I'm done tuning this thing, maybe I'll have enough posts to get out of the Seaman Apprentice rank :facepalm:

Re: The beast comes to life!!!!

Using the instruction I found the timing marks and adjusted the points and arm to roller to the carb. One of the points was loose and fully closed. I assume there could have been more of the issue. It is still amazing to me that the motor running on two cylinders could be heard on the video. But as is know by all, I am new at this (old but new at this).I am hopefull that this Saturday's test will be waaaaaay better than the fist one, although nothing exploded

Hittin' on all four now!

Hittin' on all four now!

Hittin all all four now (I think). Check out the vids. I adjusted the carb screws and then it would not start again. Where can I find the settings and proceedures for adjusting them? And when I pull the throttle to idle, it dies. So I'm sure there is adjustments that need to be made. But a definite improvement! Thanks for the help, I'll pay it forward, I'm trying to get other guys interested in this hobby.

Re: The beast comes to life!!!!

If I remember correctly, the low speed needles initial setting was 1-14 turns out from lightly seated. The high speed needles were 5/8 turn out. Pull up on the black pointer connecting the high speed needles and turn it 180 * and rest it on the housing. Now you can adjust the high speed needles individually. You will have to do that at full throttle. Just turn them alternately a little bit and listen for smoother and faster running. After you get them set drop the pointer on them and using it to adjust them the same, get the highest speed.

Re: The beast comes to life!!!!

Sorry, that was 1-1/4 turns open for the low speed needles. Adjust them by pushing down on the caps and using a flat screwdriver. Adjust for smoothest running.

Re: The beast comes to life!!!!

I think that I turned the low speed jets in opposite directions. My bad, lack of experience...Anyway, I am adjusting the entire group of needle settings and start from square one. Any further instruction on synchronizing and especially the second position for timing (there are no marks at second 90* spot). After lining up the marks on the flywheel and the block, they the distrubutor. I set the first set of points. The distrubutor tries to move while doing this proceedure, I just made sure it was aligned when tightening the points. But then to set the second set, there are no position marks, unless I shouldn't have gone clockwise approximately 1/4 turn on the flywheel (90*). I did not see how to make sure I'm set in the right spot to gap the points. Looks like one more time in the garbage can before the lake.

Re: The beast comes to life!!!!

Best you can do is just set both points to .020. Make sure the gap is as large as possible, hold the flywheel steady and adjust the points to accept .020 feeler gauge, but a .022 won't fit.
