RE: 4 stroke Engines
Mr Stockton,
I really don't know much about the TT .75, but it seems to have a reasonable price and it is as light as the Saito .72, which I do own.
Previous knowledge about the TT .91 reveals the following:
1. It was a real elephant weight-wise... not true of the new TT .75.
2. It had all sorts of issues people began threads here about, involving the choke mechanism and assembly, which the engine cannot be run without... I don't know how and if it applies to the TT .75.
3. It is dead reliable and last very long, with no other problems I can recall.
4. It has a nice actual purchase price.
Maybe it is time for you to begin your own thread here, asking specifically about this engine...
