Got my '76 TR6 3 weeks ago & have replaced the plugs & coil wire. Parts take a while to arrive out here on the far East coast. Points were just okay & the new wires with all the rest of the usual ignition bits will be here soon. Car does not miss & pulls okay uphill, etc but just feels underpowered. Backfires occasionally. The timing was off 28 deg & we reset to 4 deg BTDC & it would run but not drive - sputter, sputter. Reset to about 9 deg & it runs & drives again almost same as before - not good, but driveable for a weekend spin. This seems like carb trouble but can't be sure till all ignition bits are in and I could be premature in thinking carbs before ignition. Nobody around here knows anything much about Brit cars unless they read my shop manual - I can do that myself. The air valves are free floating but don't appear to be quite in sync. Thinking of buying a rebuild kit & wonder if a Grose-jet needle and seat is a better way to go with the rest of the kit. Will have access to a Unisyn and needle valve adjusting tool this weekend. Should I mess with this if the ignition parts don't arrive or just leave it? The car has pretty good compression - down about 20 PSI in 2 cyl - what the hel*; it's 28 yrs old right. Any advice would be appraciated. I had SU's on my old '67 TR4A & never had a moments trouble so this is new to me. Thanks.

Thanks for responding. The plugs were basic black; not too dirty but nowhere near light colored. My buddy was on the timing light so I can't say whether it advanced or advanced smoothly - didn't think to ask. Will check with him. TR6 conked last nite & had to tow it home & so far cannot restart. Still waiting on ignition bits but will install the new points I have & see what happens. I have spark and fuel but only have 2.5 lbs pressure on fuel line according to vacuum tester. Also suspect dirty gauze in fuel pump & will pull the pump if it won't start with the new points. Have the Unisyn but will wait on ignition bits before fooling with that. Ain't sports cars fun!!
