[Mg-t] trouble starting

[Lawrie Alexander]

Oliver,

The new fuels which have ethanol in them vaporize more easily than gas used 
to. The heat of the engine is transmitted via the manifold studs directly 
into the carburetors so you end up trying to re-start the engine with fuel 
that's not mixing with the air the way it should. This problem has affected 
lots of folks in recent years.

The cure I've found is to insulate the carbs from the manifold with spacers 
like the TF, MGA, MGB, etc. used. If you have 1-12" carbs you can use TF 
spacers and studs to replace the TD bolts (and new gaskets, of course). If 
you have 1-1/4" carbs, I have a local supplier of the correct size spacers 
which we had made up to solve this very problem on TCs and TDs. They're not 
cheap ($30 a pair, as they were custom-made in a small run) and you still 
need to buy 4 gaskets and studs and nuts, but they really do eliminate the 
problem.
