I have a mystery going on in my TR6, and I would appreciate some advice.
I have a 74 with 70000 miles. I've never had any engine problems. The other day I put about 100 miles on it, I was going 70 on the freeway, got off at an exit and when I started again the engine was fine up to 2000 RPM and then would sputter and fight going over 2000. I couldn't go more than 15 MPH.
I replaced the spark plugs. I checked the vacuum hoses and they all look attached and ok.
The contacts on the distributor cap look a bit worn, and I plan on replacing it. The distributor points look ok.
A previous owner put a booster fuel pump on the line from the tank to the primary fuel pump. This pump comes on when the key is in the auxilliary position. I'm not sure why this was added. I checked the filter in the primary fuel pump and it looks ok. I haven't checked the fuel filter yet.
The carb damper oil pots seemed ok, there was oil and pressure when pushing the needles back in. I have never tuned the carbs in 6 years (15000 miles). The air filters are a little dirty, not clogged.
I am running out of ideas. Any advice on what to check next?
Thanks in advance.
