Ryobi gasoline powered drill/hammerdrill

[BigGG]

So I cut a new foam filter from a briggs & straton foam filter and installed it. Not perfect, but OK for testing purposes.

Took a few pulls, but it fired up. First few attempts, it would start then die. After about 5 times, it would run strong, then die.
Next 5 pulls it ran well and would idle without stalling.

Only thing I don’t like is it takes 20-25:1 fuel mix. Kind of an oddity as everything else seems like it’s 50:1 now.

Neat tool. I might try to find a Ryobi recip saw next.

I use 40:1 in all my 2-stroke engines. I think 2-stroke oil has improved since the 20-32:1 requirements were set. My Dad's old McCullough called for 30 wt motor oil at 16, maybe 8, to 1. I could be wrong, but I don't think the engine metallurgy has changed that much.
