The photo shows the cam in place. It is the one closest to the sprocket. I am trying to build up the lobe with some JB weld. I am pretty sure it will not hold up over time, but I plan to file it down to the point where the dwell is correct just to get an idea of the correct profile that I will...
Hi, I need to modify the dwell on a cam on my Scuderi cycle engine that I built. I need to have the intake valve stay open for about 10 degrees longer so I would like to build up the lobe a bit. I no longer have access to a milling machine or lathe so making a new cam is not an option.
I was...
John,
I looked at that mixer, and it should work just fine with a bushing that they also sell. It is almost an exact match for the one that I made. Thanks for the information.
John
Can any one recommend a finished carburetor that will work on my 1/4 scale Galloway engine? The mixer that I made for it is very unreliable and I am thinking of replacing it.
Thanks, John.
Jason,
Thanks for the input. As I am using a vapor carb I guess the viton rings and oil in the fuel is not n option. Growing the piston as you explained may be my best option. How long does the piston have to stay at temp? I no longer have access to a lathe, so turning new pistons cannot happen...
Hi,
I have completed Jan Ridder's scuderi cycle engine. As of yet it will not run except for a few "pops" here and there. I am fairly sure that the problem is low compression. This engine uses no rings and relies on a very close and smooth fit between the piston and cylinder. He suggests no...
Hi Tom,
The inside jaws I have measure:
length-2.467
height-1.735
width-.738
groove width-.310
This should be enough information to start. Thanks for looking, John.
Hi,
I'm just taking a long shot here, but I am looking for a set of outside jaws for my Buck chuck. It is a 6" adjus-tru, 3 jaw chuck model 3634. Nothing on E-Bay and I really don't expect to find them. You never know.
Thanks, John.
I was thinking that it might be possible the new gears may have been machined to a higher standard than the originals. Just a thought, but if it's true it might make a difference.
Dave,
I was not very clear. I'm talking about the twin gears on the the feed reverse mechanism. They normally have plain bearings. A vendor on E-Bay is selling replacement gears with ball bearings instead of plain as an upgrade to make the gear train quieter. I was thinking of replacing mine...
