succesfull break-in ?

[Eelco]

How can one see that the break-in procedure has been carefully done ?
And how short will the lifetime of the engine be if it is not ?

Using a compression gauge will give you an idea of what kind of shape it's
in, although I dont see it mentioned often.

the compression guage tells you what you can find out for free. Sure, it
gives you actual numbers, but just rolling the flywheel with your finger
will tell you how much compression and leakdown you have.
As for the break in, if you can get it running properly then you should be
ok.
the 'sticking' problem you mentioned in your earlier post is not uncommon
with new engines. The piston and sleeve are so tight that if the engine
stops at Top dead center, the cylinder may cool and shrink around the
piston. It should be avoided, but its not the end of the world. Put a dot of
magic marker on the flywheel when the piston is at bottom. When you stop the
engine, turn the flywheel to bdc before it cools too much.

Trying to free the piston by yanking the pullstart was a bad idea. You'll
break something. remove the glowplug and turn the flywheel when necessary.

Life expectancy? some of the best tuners in the world may know, and possibly
Kreskin, but for now assume that you'll destroy your 'Newbie Engine" between
1 and 2 1/2 gallons of fuel. There are way too many variables for an
accurate prediction now.
