March 8, 2016 at 12:53 pm #33110quote SteveAbe:yes i am running in a barrel .I pulled one plug wire at a time while running made very little difference on either cyl. It wont start when the lower wire is unhooked it will start when it is hooked and the top one is unplugged. I have that wrong it is the other way around i put a new pump in it thats why i tried to run it in a barrel It has always had 16/1 gas my grandpa bought it new. I always drain the carb when done it only gets used once are twice a year so i always drain it. With it being my grandpas im kinda anal about this motor i have 4 or5 other motors so im used to these older motors.Thanks for the tips i think i will pull the head and see whats up
OK, drain the gear lube and rotate the flywheel with the plugs out like Frank suggested. Try NEW spark plugs and a different compression gage.
Do a spark test also. Sounds like you drained the carb pretty well, so that should not be an issue. Running the engine in a barrel, not under load, makes it tough to evaluate it easily.Can you do a video of the engine running and post it? Maybe someone here will pick up on something. Remember, do the easy/basic stuff first. Try to avoid pulling the head until you have verified the compression readings with a different gage, hopefully you will find a simple solution.
We realize this engine has a special place in your life, I’m sure you will get her purring again.March 8, 2016 at 6:41 pm #33121No. Don’t pull the head. Like fleetwin says, don’t tear this thing down needlessly. Do the Sea-Foam trick first and get the rings loosened up. I don’t think there is anything mechanical wrong with this motor, if it ran last year. If the head gasket was blown, your readings wouldn’t be this high. The Fleetwins have pretty good and strong head gaskets (much tougher than the 5.5’s) What is the conditions of the coils? Are they still original? If so, there’s your issue. They may spark but it may not be strong enough to run this motor. "antique coils" can degrade, just from sitting.
March 10, 2016 at 8:57 am #33191Sorry guys been out of town just got back i will try a different comp. gauge tomorrow and let you all know. Thanks for all the help im sure we will get it figured out ill get back too you
March 12, 2016 at 7:43 am #33273ok guys i rechecked the comp with different gauge about 63 are 64 pounds. Had xtra head gasket so i toke the head off looked pretty good. I tried to wiggle the pistons around when at tdc seem ok. I took flywheel off after i checked the spark the coils have been replaced at one time one is red one is dark purple the spark was real good i have a plug that ive cut the electroded off and the spark jumps from the center of plug to the side of plug good 1/4 inch real blue so needless to say im going to put it back togeather see what happens. Question for frank would it be any better for me to get 1 of your timing tools too see if that will help? thanks steve

It has spark on both, so should at least run on both cylinders, even if poorly.
March 12, 2016 at 1:16 pm #33279Did you look closely at the mating surfaces when you had the head off for places where water could be leaking into the cylinder(s)? Any signs of water or rust in the cylinders? 65PSI does not seem too far off from normal readings. You mentioned testing spark with a home made tester, how about buying one/two of those inline spark testers (only a few bucks at HF), so you can monitor spark performance while running. Did you drain/refill the gearcase yet?
March 14, 2016 at 4:54 am #33413Put it back togeather started it in the barrel and it seems fine. Hope to run it monday on a boat will let you know.
March 29, 2016 at 9:42 am #34041sorry guys been busy ran the motor on a boat and it ran good dont know what the problem was but im glad it runs good.
March 29, 2016 at 10:10 am #34042It was just a little grumpy from being awakened from a big nap. 60 year old motors might do that sometimes. 😀 😀
If you didn’t drain the carb, last time you used it, that could create a little hard starting issue, as well. Running them for an hour or so, will clear it up and you’re good for the season. If it doesn’t clear up after a few minutes of running, then likely a tear down and rebuild of the carb will be needed.
You might want to double check the connections, where the spark plug leads go into the coils. Since you have two different coils on that motor, that’s all the more reason to double check the workmanship of the coil replacement. A good mechanic would have replaced them both, when the first one died. Then again, a PO could have installed a couple of good used coils on it too.
April 1, 2016 at 7:07 pm #34186How about your caps? Leaking caps = weak spark Often overlooked! AND yes check your D-shaft too.
