but the
added snugness of the bolt against the centre iron housing is making

it

somewhat
difficult to get the threads to line up on the front iron housing so

the

bolt screws
in.  I've got 15 of 18 in currently and am having to back 3 of them

out to

either
re-do the heat-shrink or remove it all together and do the RTV alone

trick.

        Brian,

          You might try running a thread die up the threads then

chucking the

 bolt in a lathe and turning a slight taper to the end of bolt. Then

back off

 the die to clean up and straighten the threads. This might make it

easier to

 start the bolt IMHO.

I didn't have a problem like this when I did my engine but Kelly's idea
sounds good if you do.
Being a bit less "formal", I'd probably just bevel the end of the bolt by
twirling it on my belt sander.   No die cleanup needed this way.

Just don't get carried away with grinding off threads. These bolt don't engage too
many threads to begin with.
