Picked-up a 1962 Johnson 28hp (RX-10) as a project motor a couple days ago. The previous owner mentioned it sat for several years, but ran good before. So I took a gamble. It was only $50. Plus it came with a good 2 wheel metal cart.
I tried to check compression last nite, but it was hard to pull. I sprayed some fogging oil in the plug holes, and it pulled a little easier. But I couldn't give it a good full pull. Maybe about 3/4 pull at best? Anyway the compression read 70psi on both holes.
I read somewhere to try pouring some marvel mystery oil in the plug holes and let it sit for a week or so. I'll give that a try and recheck the compression next week.
Anyway, in the mean time. My library has a service manual. I'll start looking at that before proceeding on to the usual things like impeller and carb rebuild.
Is this an easy motor for a newbie to take on? Is it a good runner? Again, for $50, the cart is worth that much. Appreciate any tips or advice.
