QuestionJim,
Kevin again regarding my TR6. Thanks for the quick answer to my question about quick reving in mildly cold weather. In answer to your first point, I have seriously considered moving to a warmer climate - not going to happen (so I am told).
I probably wasn't clear enough in my first question. I just picked up this Triumph. The first couple of days it started great (it was in my heated underground parkade and the weather outside was 10 degrees Celsius) with no fast reving problems. This morning (the temperature had gone below freezing), when I started the car, it started great but immediately reved to 6000 rpm (i.e., in about 2-3 seconds). I immediately turned it off. I have tried again a couple of times however, it continues to immediately rev to 6000 rpm. I am wondering if the cold weather is simply causing the choke to stick (the car is in my covered garage though is not heated) or there is a greater problem.
Thanks again, KEVIN
PS - I am putting the car in storage for the winter later this week.
AnswerKevin,
Ok, that's a bit different. Fast idle is normally 2000-2500 rpm... what you're describing is either:
a) throttle linkage sticking on one or both carbs
b) air leak somewhere in the system
c) carb pistons sticking in the up position
d) some other unspecified problem (have to say that or the lawyers jump on me)
Seriously, give everything under the bonnet a good going over. Oil up the carb linkage, making sure everything moves through it's full range smoothly. Top up the dashpots and make sure the pistons are at the bottom of their travel. It's not a bad idea to check the diaphrams in the carbs to make sure they're not split/torn.
If you can get the car to idle at a reasonable rpm then check for vacuum leaks. One simple method is to take the can of lubricating oil with the tube attached and gently spray around the different gasket flanges. If the engine note changes then it means you're pulling air past the gasket.
I hope you get a chance to enjoy your last week before storage.
Cheers,
Jim
