I thought I had the fuel issue solved with my TT but today i took it out and I have found that every time I make a turn the truck will go a short distance and sputter. I richen the adjustment a bit and it will clear up.
Does not seem to have the giddy up either.
Sometimes it just starts sputtering going down the road or driveway. A minor adjustment on the carb and it clears up for awhile. I am going to get another carb ready and swap out again as I am about positive something aint right in this 1. I put in a new standard needle and seat. It is almost like it is sticking or the float is hanging.
But what I am noticing that bothers me most is since I got it out and running it is really running hotter than I am use to it being. when i stop and park,it is purkulating purty good.And not after running that much either. maby 15 to 20 minutes tops. I am thinking lean fuel?
Just needing some nudges as I want to try to get this thing to a point I can haul it to the cruise in at the end of the month maby.

Yea, a few more details. The tank was installed new in 2003 or 4. Clean as a whistle inside. Fuel pours out the carb when the bowel is removed. 93 octane fuel in it right now.
Carb was cleaned completely as in the ports drilled and new brass drove in and all.
new needle and seat. Glass bowel on bottom of tank like used on a tractor so i can see everything going thru. Nothing in there that I have found.Last week I found a tiny bug,I think beatle, in the inlet of the fuel bowel. I thought I found the trouble. Wrong.

Not sure but I took my engine pans off for cooling and I took the hot air pipe off during the summer, that helped. Also cleaned out the tank and installed an inline filter. Sometimes in the past I have seen where the float sticks, also check to make sure your fuel line is well away from the exhaust. All stuff you may already know. I am sure that the other guys here will have more to add.

Back when I had my '25 TT firetruck, it didn't have giddy up either! But it was all stock, this firetruck probably never made it to a fire before it burnt itself out! That said, it, like I understand many TT's, rode so rough and "vibraty" the fuel mix valve would rotate itself, until I managed to get a better needle valve/adjusting nut to keep it to stay put. Wonder if maybe yours is "self adjusting" too, without you realizing it? Does sound like maybe too lean, and maybe not advanced enough timing?
