After charging the battery and doing some P.M. on the TR3, I attempted to start the engine today. It started and went right up to 4000 RPM immediately and stayed there! Seems that over the winter the Gremlins loosened the throttle shaft link and turned the back carb way up.

I loosened the little nut on the link and the throttle snapped back into position. After tightening the little nut I started him again and he ran fine after warming up.

However, when I watch the pistons while moving the throttle by hand, the pistons don't move exactly together, so I'm going to synchronize the carbs. But I can't find my Synchrohose, so I'm off to the hardware store to get some more hose.
 
John - sorry you lost that Synchrohose. I'll ask my local gremlins if they have any info.

I cranked up my 3 yesterday, first time in about 3 weeks. Finally got some relatively warm weather for a few days. After replacing the gland seals, etc. and lubing the jets with vaseline, I've about decided that the "tight choke" problem is due to a hidden kink in the inner cable, as well as my not knowing the correct (per factory?) placement of the connecting rod linkage to the jet levers. Still experimenting on that.

If I recall, someone suggested using the "synchrohose" technique to listen to the carbs by leaving the air filters in place, and simply lifting the dampers and listening up there. Have you given that method a try?

I told The Chief about that post, Tom, but he also wanted to watch the pistons to see if they rose together. You know how hard-headed he is.

I adjusted the rear idle a little, but they were very close according to the Synchrohose readings.

The pistons rose together, but the front piston dropped faster when the throttle closed. The front carb was a little low on oil. I don't know, but I wonder if the damping action works on throttle closing as well as throttle opening.

While messing around in there, the Chief Boffin detected a little throttle shaft play. I'll have to form a committee to allocate more funds from the Managing Director.
 
John, glad to hear you got it fired up from winter slumber. Doesn't sound like you're in too bad of shape. Could an uncentered needle cause the diffent rate of piston drop?

Got Old Yeller out for a spin yesterday. Did about 80 miles. Went pretty well, but have some fine tuning to do. There is far too much pinging (which I assume is the timing too retarded) and carb(s) are still too rich. So, I have some playing around yet to do.

Hope the Managing Director at Soggy Bottom coughs of the funds the Chief Boffin needs. Priorities you know.

Ed, an uncentered needle can indeed cause the piston to drop slowly and I considered that. But it runs O.K., so I am not going to mess with it, as there is another problem which warrants a new thread.

The Chief Boffin says that pinging is usually caused by too advanced timing, not too retarded timing.

The HSTRL Soggy Bottom Funding and Planning Committee, consisting of The Chief Boffin, Managing Director, and Lab Mascots Felix Holstein, Buster "Big Boy" Turner, and Annie "Ragtime Annie" Calico met last night to discuss funding for the TR3. After three hours of lively debate, the committee decided to change its name to the Planning and Funding Committee.
