Default Myrick 4hp

Picked up my new project on Thursday a 4hp Myrick starting working on her this afternoon it seems to be in pretty good shape removed then intake on it and what I can see of the bore it looks really good.
I have a couple of questions how do you remove the hot tube chimney I was try to remove the tube for burner and it was almost rusted through and it broke off I'm pretty shure I can get the broken pieces out by cutting it in pieces I hope also how and what do you lube the main bearings the cups are packed with grease at this time any info or tips would be greatly appriciated it looks like it has a brass rod also it's serial #1128.
Hope to get her running soon hot tubes are new to me so I have a learning curve ahead of me.
Ok I wanna really thanks two people Bill for working with me in getting the engine and finding someone to transport it to michigan and Butch for transporting hear and holding it till I could arrange to get it.

Welcome to the Myrick owners club There are several experts here but I am not one of them. I just happen to own a couple. The chimney is held fast with a set screw on the opposite side from the burner opening. Mine both have a square headed bolt there. Heat will likely be needed to get the set screw/bolt free and it should lift off with some wiggling to lose the rust. I lube the mains with the same 30wt oil I use in the oiler and rod.

Welcome to the club! Do a search for Myrick Eclipse here, I know there have been several discussions within the past few years about these engines. Lots of detail about proper, factory correct gas plumbing. See if they answer any of your questions. Also, search youtube. Lots of good videos showing these engines in various forms of restoration and condition.

Brass rod indicates an older engine, as does the crank on the flywheel spoke (vs the rim).

Engine looks like its in good shape, wont take much to get it going!

Mike

Thanks Guys Ive been looking at the fuel setups and have started building one. Need to put something under it to role it around the garage first. Removed the intake on it and looked into the bore with my scope and it looks suprisingly good in there still might remove the head and check the rings and a few other things there is a broken bolt on exhaust lever so far everything has come loose hope I can get it out with out to much trouble.
Would like to find the rest of the clutch assembly the outerarm and engagement coller.

Welcome! I also have a 4hp and I'm in the same boat of needing some help with the hot tube! I got mine out and had it loaded on the trailer to go to a show and figured I should try running it before I leave. When I tried starting it I noticed that as I cranked it over the burner flame looked like it was going out. The more I turned it over I realized that it was the compression blowing the flame out.

I didn't tear into it yet, but I'm hoping that I'll be able to get some help here on the stak to solve my problem.

Good luck on your project!

Adam,

Sounds like the threads around the hot tube and its bushing could be deteriorated. I also had the same issue, however not quite bad enough to blow the flame out. I made a new bushing using a 1/2 NPT SCH XXH nipple from McMaster-Carr. The ID of this nipple is small enough to drill and install the 1/4 NPT threads required by the hot tube. The OD is just the right size for the chimney to slide on.

Mike

It's running ya:not very well but she's running found out after it started the gasket for the intake gage was leaking but I feel better knowing it's running hopefully after dinner I'll try and restart it and hopefully it will run better. But I'll probably have to remove the piston to check the rings and rist pin.
Then it will take me a week to clean my garage up and find we're I sat all my tools at.

When I was learning to tune mine it seemed like either a too lean or too rich mixture would make it labor about the same but a too lean mix will make the exhaust bark very loud sometimes and firing very late sometime firing about the same time the exhaust valve opens. While a rich mixture will also give weak hits but the exhaust note will be more subtle. What are you using for regulator(s)? How are you feeding it? Single or dual feed? A tube that is only marginally hot will also make it a tuning nightmare! Doing Paul Gray's burner mod was like a miracle cure for mine, plus it doesnt blow out in a breeze.

I,m running seperate tanks and a BBQ regulators on both lines the tube looks nice and red to me but this is my first hot tube engine the tube its self has some insulation in it also.
My setup is I hook up to a 30 inch 1 in pipe then up to my 3/8 pipe to the intake my valve isnt a needle valve just the more common brass handle valve.

Well after some thinking and luck she is now running and looks to run pretty good but I could be wrong since this is my first hot tube engine. Found there was some kind of check valve in the end of my propane hose that was shutting off the fuel when it fired I removed this and she started right up runs but I can hear the vent hiss on the regulator hope this ok or might have to change something to keep it running so all in all a good night.
There are a couple things left to do anchor the fuel lines and straighten the fan shroud to keep it from hitting as it runs also can somebody tell me how to drain the oil from the crank area and how does the rod bearing get oil to it.
Thanks for all the help guys and any other suggestion would be greatly appreciated.

Dave- she is running nice. If you put a weaker spring on the governer weights, you should be able to slow it down. The down side of slower running is it is more prone to knocking if the hot tube is too hot. The lower rod end is oiled by a pocket in the rod above the bearing. The waste oil is drained by a small hole about 6-8 inches below the governer side main bearing on the base; yours is most likely plugged. Also remove the cylinder oiler and with a flashlight, roll the flywheel over near bottom dead center. You should see a small hole in the side of the piston, this is for the wrist pin oil tube. Poke a piece of wire in it to make sure oil will get to the wrist pin. Welcome to clan Myrick!

Thanks Paul love your website for the engines it really helped me out on some things was out in the garage finishing the fuel lines up still have to figure out how to mount the one inch tube to keep it stiff and not bouncing around also my fan shroud was pretty rough so I removed it to see if I could fix it I think I might have to find a tin smith to see if I can't have one made for me.
Thanks for the info on the drain and the rod I didn't empty the cranks area so you can guess I had a mess under it after I ran it and my small cart that I put under it didn't work to well.
I also wanna thanks the rest of the guys who gave me advice thanks Harry for a great site with out the sight I would of never could got my engines running.
