Gus's Rupnow Hit and Miss Engine.

[Swifty]

When I first ran my engine, before I had made the governor, it ran as fast as it liked and I ended up shattering the ball bearing on the end of the push rod for the exhaust valve. I replaced it with a slightly larger one that I had on the shelf.

Yes Gus--Be shure and bolt that engine down to something solid.----if it starts up you will be chasing it around your apartment. That type of carburetor depends on having a hit and miss mechanism to control the revolutions of the engine. If you start the engine with just that carb in place, and no hit and miss mechanism, be aware that there is no throttle on it, and it may rev out of control. If you are going to build the hit and miss mechanism, you're fine. If you don't plan on building the hit and miss mechanism, you need a different more complex carburetor. I have a set of plans for the more complex throttled carb that I can send you.---Brian

Hi Brian,

Thanks for the expert advice and carb drawing. Will run on your carb. Please send drawing. Will miss end September dateline to spin engine. 28/29/30 Sept in Northern Malaysia . Taking the darling boss to Yokohama 2--7 October. TokyuHands is just next to Hotel !!!!!. Will be nothing much to buy as I have almost evrything I need. So Just window shop and buy nothing.

Plan to put the H&M mechanism later after I cut the mitre gears.Now planning murder. If I have to make or buy a real Dividing Head with Divider Plates.So be it. It takes a week to practice/goof and cut a good pair of mitre gears ,will do it.

Been a bad day. Missed 4 good bites.Rod bent but fish spit out bait.

Mopping up done 99.99%.
Valves lapped. Believe got it done right with a circular band around the valve and seat..
See foto.
The Viton Piston Rings not received. Put in C.I. Pistons Rings. Luckily .I bought two extra
rings.

At long last, mounted engine on a plywood base. will wire up ignition tomorrow.
Fuel tank will be done tomorrow morning. Come Friday 27 and 28 ,hopefully will see engine started and spinning. Cleaned all the gunk,buff the engine base and frame for a foto shot. See foto.
Hopefully with the experience gained from starting the Webster,the H&M will be easier to start.

Hi Paul,

Went to usual fishing tackle shop. Slyly asked Doris for the smallest Shimano Reel bearing she has in stock. Got one slightly bigger (foc)but ID 5 mm and
OD 8mm. Hope this will do. I was too lazy to walk over the 1 km stretch bearing shop.My H&M is the only engine with Shimano Bearing!!!.
Should spin engine this friday.Will make new petrol tank. Please advice your petrol tank location works well for fuel delivery?? Carbon Copy tour tank.

Gus--Just set your tank up so that when it is full of fuel the fuel level is 1/2" below the centerline of the carburetor.

Hi Brian,

Thanks for the info. This will cut time wasted.
Will be using the prescribed carb for H&M. May buy a O.S. Carb for the Vroom
Vroom to run in engine. Later will the H&M going.

With the engine completed and engine on my P C desk,Its so relaxing with a sense of accomplishment..

Gus, I'm looking forward to seeing yours start, my fuel tank works well in the position it's in. If I put it higher, it would interfere with the exhaust mechanism.

Gus--a hint about cylindrical gas tanks. I had one of those cheap halogen pole lamps that set behind my easy chair. The electrical components burned out, but the column was about 48" tall, made of beautiful polished 1" brass with about a .045" wall. I tried to make it into a gas tank by soldering ends into a section of it, but failed miserably---I couldn't get the solder to stick to it. Then someone told me those brass lamp poles are sprayed with a clear lacquer to keep them from tarnishing. Once I sanded off the lacquer (inside and out) I was able to solder it and make many beautiful gas tanks.

Gus---Leave them slimy old fish alone and post a video of your engine running. I can almost hear it from here!!! When are you coming to Toronto??

Hi from England

Gus, excitement is mounting over here too have you got your "o" rings yet or are you going the old fashioned way ?

Can't wait for the first "pop" preferably followed by many hundreds and thousands more,.

Shimano bearings, impressive, They make great derailliers for cycles, best in the world, but I didn't know they made fishing reels

ABUs and Mitchells tend to be the hot ones in the U.K. But that's inland freshwater fishing (the odd trout happened to land on the hook, purely by accident )

Regards Mark

How's the fuel tank looking Gus?
