I'm smelling gas when the Bonnie has been parked in the garage. It is also backfiring when I restart a hot engine. One loud pop and then it starts and runs fine.

I have TOR's and the standard rejet that goes with it. I don't know the new jet size.

I wondered if I'm running rich or if it's something else. Is there a chance I can do adjustments on my own?

I just re-jetted, tuned, and balanced my carburetors, and I haven't done anything that mechanical since I swapped out an alternator on my old Datsun back in the 90's. Now she runs smooth as butter. All you need is the right tools, a good manual, and free day to take it slow.

When I went to re-jet and tune I found that my system was far too rich on account of the Pilot/Idle screws being wide open, and I mean five or six turns out. That overly rich condition resulted in a lot of gas getting mixed in with my oil. I also got a back fire whenever I started the engine warm, but after the tune it disappeared.

Have you checked for any fuel leaks?

Thanks for the advice. Yes, I did check for leaks and found none.
The dealer service guy suggested I turn in the carb screws one full turn, but he thinks I need a special tool for that. Is that correct, or can I improvise something?

The dealer service guy THINKS you need a special tool?

I think he was referencing the 'D' Tool that removes the manufacturer's anti-tamper caps on the Idle screws. Mine was an earlier model, so I didn't have to deal with them.

Search the forums for some of the creative ways people have gotten the caps off or just check out newbonneville.com, I know they've got them.

The d tool adjusts the screws, you need to get the tamper proof cover off first, if so equipped

My 2005 T100 came without anti-tamper plugs, but with the idle mixture screws that require the "D" tool. It was about then that Triumph switched from the anti-tamper plugs with standard slotted head screws to no plugs plus the "D" shaped head. The tool is available at NewBonnieville.com. Some have fashioned a tool rather than buying one, but they are relatively inexpensive and you don't want to risk messing up the screws. You can also get tool-free idle mixture screws from NB. If you use a mirror and small flashlight, you should be able to see the shape of the screw head.

D-tool Use a spent M-16 casing & flatten 1 side. Works real well. :hammer:

I don't think I can get my hands on a spent M-16 shell casing, so perhaps I'll just pony up for the D tool.

Thanks to all for the advice!
