[TR] TR4 engine question

[David P]

Incorrect timing, crappy plugs, tired primary wires lead to ... wait for 
it.. carbon buildup. As to fresh engine.. head gaskets aren't what they 
used to be and coming from those tariff

countries sizing has long been an issue to proper fit. Dropping the head 
to the block can be an easily botched process, damaging a new gasket is 
common.. Old wiring harness' frequently leak voltage

all over the cars... generators make voltage as long as they are 
moving... DP  Or... depress the accelerator pedal fully at switch off. 
This will disrupt the air flow over the jet head and may work for some.
