Rebuilding a model 7266

[WhyZed]

I'm rebuilding a D409 motor which is the same as the D601 in the sense that the crankcase & cylinder separate.
I didn't use or need a ring compressor to put the cylinder over the piston and rings.

I made sure the ring end-gaps were opposite each other, oiled it all up, pinched the rings (one at a time) with my fingers & it went straight on, no problem..

A ring compressor might help but it is not a required tool..

There is play up and down and side to side. I don't have another one to compare it too, but I would think that the amount of play I am describing can't be good for the longevity of the engine. I am measuring end play at the end of the crank. I put a dial indicator at that point and came up with 0.028, so if that is the correct place to measure it, it seems excessive.

Also, I found a source for lawn boy engine paint on ebay, but it is $11 + shipping for a 4.5 oz can. Anyone found a better source?

actually i just got through with the rebuild on my 7084, rustoleum engine enamel grabber green is so close its hard to tell them apart. just waiting to obtain some wheels!!

It went for $88. Maybe that's not too bad but it was more than I wanted to spend. There are listings for Stens replacement pistons on ebay for $30-40. Are they any good or is it worth the extra $$$ for the oem?

I restore vintage lawnboys, and stens pistons are dimensionally correct. Rotary brand pistons are junk.
