TR4 Dieseling/reply

[John Howard <trjhhow7@home.com>]

Thanks for all your good suggestions.

I fear the problem is in the combustion chambers, where I probably did a
half-a.....d job grinding down the rough edges. Before I sink into total
despair, however, i will do what many suggest....try retarding the
timing and leaning the mixture. And maybe simply rely on the in-gear
shut-off if I can't rectify the problem. I can't face tearing off the
head at this point. 

I'll kep you posted
