Has anyone installed a roll pin to hold the spark rod lever to the adjuster rod and if so what size roll pin?

Yes and sorry do not recall size. Have had it in and out several times and it's doing its job. My hole was worn over sized so had to trial fit till I found one out the box that worked. If you used one, do not go past the lever on the bottom side it will jamb into the steering column.

I went to ACE. They had roll pins. It just a 1/16 larger. They work great.

Sorry I missed typed. The drill bit is 5/32.
I went to the garage to check my notes.

Steve your very vague in your descriptions, so you drill it out to 5/16 and install that size pin?

I tap it and put a machine SS machine screw though it. Easy to remove and replace. No more slack. Don

A roll pin is putting a straw into a hole where a dowel should be and reduces the shear by about 50% on a small hole and way more on a large hole. I would use a nail like a farmer before a roll pin on anything based on my experience. Yes they drive into a sloppy hole but a proper drill bit and pin secured will have more strength. Even a split pin is much better than a roll pin.

The timing advance and throttle doesn’t have much force. If you’re worried about safety, put a wire through the roll pin. Not a big deal. If you’re putting that much force on the timing advance and throttle you might need to rethink your driving habits.
