I'm excited to say that after 36 years in hibernation, my 1979 T140E Bonnie came to life this afternoon!! Yay!
I just installed a Pazon EI system, rebuilt the carbs, changed all the fluids, new battery, plugs and plug wires, and with a small shot of starter fluid VIOLA!! It came to life on the second kick!
After warming it up gently, I set the timing and adjusted the MKII Amal carbs. It idles quite nicely around 800-900 rpm, though the left cylinder does seem to be burning a little richer than the right. (as evidenced by more smoky exhaust only from that side)
After shutting off the engine and letting it sit for a few minutes, it starts immediately on the first kick without any issues.
Unfortunately, if I let it sit for 30 min and try to start it (using the cold start plungers on each carb and cracking the throttle about 1/3 open), I get absolutely nothing. Hit a short blast of starting fluid in either cylinder again and it starts immediately.
Questions for the group:
- Any ideas why cold starting is so hard without starter fluid? I don't want to continue needing it as its hard on an engine. I've seen a few docs outlining how to ream out the pilot jet on the carbs which I didn't do when I put in the rebuild kit. Wondering if that might be a problem for cold starts when the pilot circuit might be most needed for supplying initial fuel for ignition?
- Any thoughts on how to even out the left cylinder that has a bit of a smoky exhaust?
Thanks in advance for your help to a newbie!
