I just bought a 1969 TR6 Racing Edition (SCCA and street legal). It can start but I have to press hard on gas pedal to 3000 rpm to hold idle to warm up for a while ( at least 5 minutes) and can slowly reduce to above 2000 rpm. However at 2000 rpm or below he engines dies out. Tried to repeat many time to warm up but the engine dies out at idle of 2000 rpm. The last owner said that he had to clean out the fuel filler due to fuel tank rust. Should I have to clean the filter, or replace the fuel tank. Some one else said it could be due to carb diaphragm leak or dirty? I am not a mechanic or any with fixing. I need to know so I can deal with honest repair shops.
The rust in the fuel can raise a red flag. Check the fuel filter for contaminates including rust. If it does have rust in the filter then change the filter and I would have a mechanic inspect the tank first before replacing it. The rust could also come from a metal fuel line.
The idle problem could be the diaphragm or it could also be clogged idle circuit inside the carburetor. This would require a carburetor rebuild to fix the problem.
Other problems could cause this problem but I would start with this first.
Let us know how you make out.
Thank you TechHelp2
Your recommended steps comfort me about what to expect. I will bring it to the garage near by this week and I do not do the fixing. Can not wait to have the problem fixed and drive it when the weather warmer. Will let you know the outcome.
Have a great day.
