Triumph TR6 - Stalling

Tonight I attempted to make it to the local Cruiser Night which has been my goal for two years. About a half a mile away she stalled and three hours later I limped home. It will struggle to start and then go a couple hundred feet and stall. It would start easier after I left it sit for 30 minutes or so.

I just got it inspected and have only driven it about 20 miles with no problem aside from running rich. I pulled the plugs and all of them had a lot of carbon. I haven't got around to adjusting the mixture yet.

The carbs are getting gas and I checked the needle valves to see if they were sticking, which caused a similar problem before. I removed the fuel lines and connected a hose to blow into the carb to make sure they the needle valves weren't stuck. Most of the ignition parts are pretty new. I drained the tank a couple of years ago and put in fresh gas, but since I haven't driven it much, I wondering if the gas is bad.

I know 90% of the time starting problems are inition related but does this seems fuel related?

Mark,
Have you converted to electronic Ignition? A bad module will do that. As soon as it warms up it fails and as it cools it will work again.

I still have points. I did pull the dist. cap and scraped black crap off the contacts(?) under the cap. I could swap it out with an old spare cap to see if it helps.

Mark,

Since you already know it's rich and plugs are black, I would sort that out first and then look at other things if the problem still exists. In general engines will run rich cold but are less tolerant to the richness when warm.

It may not fix it but it sure would make sense to remove one possible condition before looking elsewhere.

That's just my opinion and how I would attack the problem.

Good luck.

Mark You have answerd you question with your mail. Yes bad gas, US gas goes off quicker than EU gas! dont ask me why but it is a fact so until you drain the c---p you have and replace with fresh you are wasting your time. Start affresh and we can help you. CP

I'll siphon it this weekend, change the plugs, and try to adjust the mixture. I'll let you know how it goes. For the yard equipment and snowblower, I use gas stabilizer, but I forgot about the Triumph.

Thanks for everyone's assistance!

Good call Clive.

It didn't sink in with me that Mark was essentially saying he had 2 year old gas in the tank.... with no stabilzer.

Mark... you're on the right track now. Get rid of that old gas and replace the plugs and check the mixture. The current mixture setting may be alright with the new gas.

Use that old gas in your lawnmower and when that quits running go for a ride in the TR.

Bad gas was the culprit; it was a nice shade of reddish/brown. Fresh gas and a new fuel filter, she started right up. I apologize as business travel has gotten in the way of my hobby.

Thanks again,
