Starting issues with Turbo
Posted by: bmarsh52 ()

My 65 180 turbo is having starting issues after sitting for a couple of weeks. The car will not start except when given a shot of starting fluid into the carb. I know gas is getting to the carb because if I pump the gas pedal I can see gas squirting inside the carb. I have tried adjusting the choke as Matt specified in another post. I have also tried setting the choke lean one mark as the factory manual reads.

Once the engine starts on staring fluid I have to keep it at around 2,000 RPM until it warms up slightly. If I don't stay on the gas it will stall.

The gas always has Sta Bil added when fueling and once warmed up it starts and runs fine.

Another club member Fred Marx is having a similar issue with his newly rebuilt
150 turbo.

What should I look for?

Try gradually richening the choke setting- instead of one step lean, try 3 steps rich.

"Choke has to close for a turbo to start" was a phrase I heard 40 years ago, and it is usually true. When my 64 Spyder would not start, usually the choke was open slightly.

Plugs gaped at .030"?

Tried other fuel station premium?

BTW, does "couple of weeks" mean 2 weeks or two months?grinning smiley

Frank,

Not sure about the age of Fred's gas but I am sure it was premium. Both cars have Sta Bil treated gas.

Couple of weeks means two weeks for mine.

Will have to check with Fred on the plug gap but when the engine was installed it fired right up and we ran it for 20 minutes for break in. It has been a little over a week since it last ran as the starter had to be replaced. Will try closing (richening) the choke setting as you and Kevin suggested.

Thanks

I can leave mine for weeks on end and usually less than 10 seconds of cranking and it fires right up. No lifter noise either.

Bob, Frank,

We set the plug gaps to .030
Last Tuesday, it was 50° out and started up fine three times, Set the timing to 24°. Engine was warm and then stalled trying to reduce idle with idle screw and then starter failure.

If choke is closing fully I would look at idle circuit restrictions.
