CT Rebuild 375 (295) Robin Engine Won’t Run

[JodysCars]

This makes me nervous…I just received my 375 CT Rebuild today. They didn’t send me carb studs and mine where left in my core. I was just trying to find the studs online and ran across this post. Anyone know where I can find the studs or know the specs on them? I kept my flywheel and fan so they didn’t send me one.

Their add indicates they have a 6 Month Warranty on their engines. Have you brought this up? Is their warranty just blowing smoke?

The odd thing with the compression on this engine is that we don't know what it should actually be. It is a "375". Not sure if the 375 is CC, or just a motor designation for their re-worked 295. My understanding is that it is a 295cc engine bored for a 350 piston, and some head or block work. To get it to 13 HP, it either needs to have more displacement, better flow, or higher compression. CT should be able to tell you what "normal" compression is for this engine...but I don't think you can consider stock engine compression as "normal" as we aren't talking about stock piston size or stroke, and we don't know what was done to block or head, but I can't imagine anything lower than normal stock compression would be good. I would expect higher compression. I would be nice to know exactly what they do to the 295 so we can figure out what the compression should be.

The oil leaks look like "red" oil, similar to the assembly oil I use. I wonder if its leaking seals or if its just sloppy work.

Hope the new flywheel takes care of your issue.

Here is some interesting reading from 2018.

Well I got the replacement flywheel, installed it, reassembled the engine and installed it back onto the cart. Test ran it for about 30 minutes with no issues. I’m going to run it some more throughout the day and then do an oil change and see how the oil looks.

Right now I’m just doing some trial and error testing with a few drive belts. The one that was on the cart is a Dayco 0403-166. The replacement that I got locally is a 72054-G01 and it’s just slightly longer. Just trying to which belt works best.

I’ll report back when I do the oil change.

I think you will find the standard 72054 will probably be better for you.
