Well group found a NIB TT10 GP at West Wales models UK ( his last one) have several with Davis heads so I have a spare, if I get lucky may be able to find a Davis head for it that angled needle a nice feature martin

Martin,

That TT .10 is a nice engine.

It has a longer crankshaft thread than the OS .10 or Magnum .10 so you can use spinner.

Dan I lucked out, had he had 2 would have gotten both only one in stock, price very fair about 43UKPounds but you knock off 20% for the VAT tax over there, we do not pay it, do the math on the exchange rate and approx56 to 58 USD maybe 10 or 12$ shipping around $70 to the door, An OS10LA from Tower is $63 martin

I see your TT has a straight needle the one coming has that nice 45 degree offset to the rear

Dan Vincent

Hi Martin,

Yep, mine is a very early one so I would imagine an offset needle valve would be an upgrade to eliminate finger nipping.

If I remember correctly the guy who designed the Thunder Tiger 10 was an ex-OS engineer.

The Davis OS head is supposed to fit the TT and Magnum .10's.

AMB

Hi Dan yes the tts and OS10 are the same head fit but sadly they are out of production by Davis think he still has the OS10 LA head since the engine still out there but a no fit on the TTS orOS FPs martin

TT10 FUEL talked with Bob Davis today and asked if his ABC fuel can be use He said yes since ABC martin

Found the lost one on the shelf complete with the Davis head ( the one from the UK not here yet) appears this one for a virgin engine has the best compression yet of any of my TT10s
put a few drops down the carb compression 1 1/2 turns out on the thumb screw about 10 or 12 quick flips and off it roared. I was about to start turning the compression screw in. no need and no kick back just went off martin
