Model T Ford Forum: Forum 2010: I have a loper? help...
Top of pagePrevious messageNext messageBottom of page Link to this message  By James Chochole on Thursday, December 30, 2010 - 06:35 pm:

I started my T today with new plugs, Patterson coils, rebuilt coilbox and new generator. She started fine and ran smooth but when I advanced the spark she began to lope and sounded like she was firing on three cylinders? I pulled plugs and all 4 fired well...what gives? Anyone have an idea?

Thanks,
Jim Chochole

Did you let the T warm up?

Cold starts and the roller timers have thick oil on the contacts, hits some misses some til things warm up.

Still on battery or did you switch to mag?

Normally ignition is source of missing like that, but could be the carb setting too.

I always richen the mixture a 1/4 to 1/2 turn before starting a cold engine. After 30 seconds or so, as it begins to warm up, it will begin to lope. Leaning it out clears it right up. I couldn't say if that's what's going on with yours or not.

Do you have the pan bolt under the timer in correctly?

I added an Anderson timer from an older one and it didn't lope with the older- so no bolt issues. Could be carburetion- maybe I need to lean her out? I had it on mag and bat and loped on both.

I've noticed that letting the newly rebuilt engine on my Model T warm up good before driving off really makes a big difference in how smooth it runs.

If I get in too big of a hurry it sputters along. I'm learning to be patient when starting and driving my Model T.

Turns out- my bolt was indeed flipped nut-side up, and so I took it out and now it is nut-down. I was also running on a Milwaukee Short-Proof timer and changed to the metal-cased Anderson. So the contact post for a cylinder was immediately over the nut when I advanced the lever...this could fix the issue..Stay tuned as tomorrow is 55 degrees and I am gonna drive the T again! I hope this solves the lopery!

Thanks gents!
