It's funny that she would watch you torch yourself, it sucks that she is gone.

Many many tales of dogs alerting their hew-mons that the house is on fire while they sleep and other heroic deeds. Dogs are better than us in many ways and we should have them in our lives as much as possible.

Denny should have another dog, possibly two, and not of the exact same age.

I originally got a welder, watched a few video, never got an arc. After returning it, I learned the negative clamp was to complete the circuit not just to ground the machine...

Uh oh. Well, maybe you were a little too hasty. Are you going to get another welder?

Grounding is important (who knew?) and a lot of people have upgraded the grounding clamp that comes with a lot of the beginner/basic machines so that it gives a more positive connection each time.

So my next question is, is it safe to weld a plate that connects the green part and the red part? (I don’t know the right terminology) Or are they supposed to move independently? Working on mocking up the new engine mount.

Also, how thick should the steel mounting plate be?

The part in red is not hinged is it? It looks like it is just "vibration isolated" from the surrounding frame with rubber mounts, but I am not 100% what I am looking at. The articulating or pivot area looks to be north of the green line.

You are correct. Not hinged.

I believe I’ve seen maybe some up and down movement from those circular “bolts” but I may be wrong wrong.

The big block mounting plate that I bought from Go Power Sports in order to put a big engine on a kart that originally was built for a 196cc to 212cc was 1/4" thick steel and 90 degree bends on either side for additional rigidity. Once welded in place, ( by my local welding shop ) it actually helps stiffen the rear of the kart. You should buy one. It is several times stronger than just a flat plate of the same thickness and has 6 nice long slots for mounting either a 301cc or a 420cc. Very well worth the cost. Say good by to mickey mouse, and do it correctly. You won't regret it.

No it is not ok to weld the red part to the green part. It is designed to float for the suspension.
It looks like he fixed them together already by mounting the engine. It was just done with bolts rather than welding. What could happen?

Ive seen you speak on your history, is why I ask.

I looked and looked but got quickly frustrated by their garbage search results (which include 'everything but the kitchen sink'). Got a link for it?

Good thing I asked. @Hellion is right I did have it bolted together, although it was poorly done. But I also didn’t travel very far.

Then my next question is with about 101lbs between the engine and add ons (torque converter and gearbox) should I weld the plate to the red part or the green part? Wondering which is best for handling the load without compromising the rideability.

I did see that on the site. My issue is between the big engine and gearbox, I don’t have a lot of room front to back. That Gearbox is pretty snug under the engine and hate to spend the money and get something that won’t fit and would be more of a headache that something custom.
