I have an old Pope 2 stroke Ezi Start which I have 2 questions on this old girl. 1. Is this model have points of electronic ignition? 2. The mechanism as shown in the photo I assume to be some sort of decompression mechanism, I cannot see how this would work based on what is evident in the photo, maybe there is something missing? If anyone can shine some light on this it would be appreciated.
The Ezi Start is complete. It is a hilariously simple, and it used old technology.
It is friction operated - via the rubber tip touching the underside of the starter pulley. This would engage the head decompressor valve when cranking the starter. Simple - but effective.
This is unlike the Victa approach - that used a vacuum system.
Hope this helps. ------------------------------ Jack
Unfortunately the valve needs work, it's seized at the moment, probably with years of carbon etc, build up. The plan with this one is to get it running properly then pull it down and to a meticulous resto on it. One more question Jack, going by what you see in the photo do you think the governor linkage and flag look to be in the correct position?
Hi all, good news I freed the decomp valve ok and the mowers starts first time. I still think the governor is not quite correct as the thing will idle perfectly, but when the throttle is opened to accelerate the engine runs really hard, there does not seem to be any happy medium. Most anxious to try to find a diagram of the governor set up for this model. In my previous photo it looks to me like the governor flag is too far away from the flywheel to have any real benefit. Uneducated guess only. I will Google to try to find answers, but if anyone can come up with an original setup picture that would be great. Cheers, and Happy New Year.
If you can regulate the throttle by moving the throttle butterfly shaft, then this might indicate an issue with throttle springing.
This machine would have originally had a flexible Bowden throttle cable. Your images do not quite reveal the throttle set-up on this Walbro carby. Does it have a throttle spring to keep tension on the throttle?
Yes Jack it does have a spring at the end of the cable. I'll check out your attachment and i'll get back to you. Thanks again. I have a sneaky feeling that it's something to do with the governor flag, because as you can see in my original photo that the flag sits a long way from the flywheel?
Thanks Jack, that diagram has helped a lot. If you look at the governor linkage my original photo and then compare it to the one in the diagram you have attached, they seem vastly different. I'll take the cover off the carby and post a more detailed photo up at some stage. Thanks again, much appreciated.
OK guys, i've removed the cover and included 2 pics of the throttle setup. The engine will start ok but will only run an slow idle or flat out, there is no in between. As far as I can tell all linkages and springs are correct and the throttle works properly. The governor linkage I was concerned about seems to be the right shape (to me anyway) to clear the cylinder between the flag and the carby setup. (As in original photo). What I have noticed is that in the exploded diagram that Jack sent the throttle cable seems to be coming in from the front of the engine, but on the actual mower it is coming from the rear (fuel tank end)?
Update on this: I have actually made another governor linkage that when attached brings the governor flag closer to the flywheel. But on starting the engine the same symptoms persist, so I guess the governor linkage as original is ok.
Think I have it sorted. I put the original governor linkage back on and the only other thing I changed was the position of the "L" shaped piece where the knob on the end of the throttle cable attaches. I turned it upside down which moved the cable to the bottom of this piece instead of at the top changing the direction of momentum (if that makes sense). Still very touchy on the throttle but now I can get an even throttle response wherever I set it to. Thanks for the input guys, now the restoration starts.
I have not heard back from you on the throttle shaft test. If you can govern the engine that way, it would indicate a linkage or spring problem.
The obvious thing here is an incorrect gov spring. The gov spring balances out the forces exerted on the gov air vane to produce a full rpm range. This is p/n 7503-1-34.
