I have a TT .28. I learned a number of things on this site. One was that my TT has an air-bleed carb, rather than a two needle carb. Adjusting the idle/slow-speed air bleed screw is back-wards of a two needle. So, if someone tries to help you, and doesn't understand air-bleeders.... he/she is probably turning the idle screw in the wrong direction.

The other was that the little engine wouldn't suck fuel with hand turning at all. With an electric starter ( my electric starter is VERY similar to the $19.00 dollar one already suggested above) the fuel was easily drawn up into the line. She then started easily most of the time. regards, Rich

p.s. When you get the electric starter, you may find that you have to reverse the rubber "cone" so that it will fit the smalli spinner or nut of the little .25 engine. RG
