About four weeks ago set up fast idle and curb idle. I got it dialed in perfectly and worked fine. Then yesterday after sitting for a week fast idle gone and had to feather the throttle to avoid a stall. The carb was never touched. The battery is weak and need to replace soon, would that have...

OK, got fast idle set right and set curb idle with solinoid.. However when I hit the gas engine revs up off the pedal and doesn’t drop. The plunger doesn’t retract automatically have to pop with screwdriver to release. What’s up? Choke issue ? I’m baffled.

Need advice how to set up, hopefully with illustrations, properly these adjustments. Problem is choke works fine @ cold start (1500-1700 rpm) but as engine warms and I kick down on throttle it doesn’t disengage. I have to manually increase the throttle and release the fast idle screw. What’s up...

Help ! If by chance you’ve see my recent posts I was dealing with an internal fuel, which with advice of many you guys I fixed that problem.I carefully reassembled and put it on the car today. It started right up and fast idle perfect. Checked it and fuel was almost gushing where fuel line...

With the helpful advice and encouragement of you guys, repaired ( fuel bowl leak) my thermoquad, thanks again to all. But if it acts up think I ready for something brand new. Do not want to change the stock intake, which is a spread bore. Looking for something that will bolt right up and...

Have my Thermoquad apart and with a suspected internal fuel leak. What can I use besides gas to fill the wells to test for leaks. Thanks

Seems fuel bowls are dry on cold starts and restarts after a few hours.When cold have to crank for 8-10 seconds to fill, then it starts quickly. Holds steady idle (1000 rpm) and NOT running rich. No evidence external leak. So would think an internal leak, but plugs are clean and given not...

Had car out to local cruise in Saturday. Cold start fine, drove about 30 minutes to event, arriving @ 8:30. Decided to leave @ noon. Crank and crank no start. Carb getting no fuel, had more than 1/2 tank. Pulled fuel filter, clean.fuel pump working. Put one short shot of starting fluid in carb...

Does anyone have an illustration showing where this spring attaches? Also advice how to adjust choke pull down so as to have 5/32 opening on cold start. Problem I have is choke is closed at start. Any help especially photos or drawings most helpful. Thanks Charlie

Just finished a meticulous rebuild on the TQ which turned out very well. Set up the fast idle and curb idle per specs. Cold start extremely rough and idle drops quickly from 1700 rpm to 1000 ( fast idle cam in correct position) and ready to stall out if I don’t work it. Once warmed up idle...
