Had a few minutes today and reran the norvel 074 AJs head starts easy running around 10500 top flight 8x4, idle good around 5k
good response no bogs on going to full throttle As far as the TT 07 goes I am told not a lot of power runs ok, Davis does not think
it would make a good conversion due to glow preformance, the TT10 is a whole different story little powerhouse, the idle on the 74 is not good with the 7x4. Andy you are on the money the 074 is getting better with each run and being very careful with the stock rod
and you are also right on the diesel set up 1/2 turn on the compression and ditto for the needle is the difference between running great or like crap the newbies would have some problems before they learned martin
