Stromberg LF
Bought this LF off of eBay. Cleaned it up inside and out. Very little wear on any of the parts. Went to install it today and realized that the flange bolts threads are small then manifold holes and course thread. Spacing is correct. Is this the correct LF for a T, or did I not do my homework before I bought?

Re: Stromberg LF
Yes it’s for a T. Flange holes are coarse and 3/8”.
If flange holes line up with intake holes, you’re good to go

Re: Stromberg LF
Thanks. Won’t be able to get back to in until Wednesday night. I’ll let everyone know how it runs.

Re: Stromberg LF
Picked up some 7/8” long bolts today. 1” seemed they would be too long and 3/4” seemed to short. Found some at my local auto parts store.

Re: Stromberg LF
I need help setting float level. Starts but dies immediately. Actually, two free starts for a half a second.

Re: Stromberg LF
any number of things could be wrong, but at this point, with a car which will not run at all, your float level is almost certainly not the root cause of this situation
advice: remove acorn nut on top of float bowl. Using a dial caliper or height gauge, measure the "stick out" of the slotted/threaded shaft past the clamp nut (will be around 3/32" or so). Write that number down. Now, if you insist on working the problem via fuel height, you'll know what to set it back to when you're done.
There are two distinct fuel circuits; the idle circuit which has the adjustment on the side of the carb and is kept from turning under vibration by way of a little spring, and high speed adjustment which is the knob on top which rotates via linkage when the throttle lever is moved. That knob can be rotated/adjusted as necessary relative to the lever that actuates it. It consists of a very solid "notched" fitment to the lever. Use great care (and penetrating oil) freeing it up so as to ensure you do not break the screw
if fuel is not getting to where it needs to in a timely manner, you likely have some blocked jet orifices.

Re: Stromberg LF
I took every bit of the LF apart and cleaned all the orifices. Set idle and high speed jets to the the manual. 1/2 turn open on idle and 1/4 turn open on high. Three cranks choke ignition off. One crank ignition on fired right up for a second at a time. Played with idle screw both ways a few time. Same results.

Re: Stromberg LF
One final thing: the LF will not operate properly on the FORD style choke lever; it must have a Stromberg or equivalent control which will hold the choke plate in "choke", "rich", or "run" positions so that a properly rich mixture can be had at first and then slowly leaned out while the engine warms up

Re: Stromberg LF
Thanks I’ve already down loaded and printed a few months ago.
Such a simple fix. One little piece of the old fuel screen I missed was keeping the float needle from seating. I had disassemble and had cleaned everything and but Still missed it. Must not have had my readers on. Started right up and running very nice. Still raining out but should stop soon for a test run.

Re: Stromberg LF
Very pleased the way it’s running. Accelerated right up to 40 very quickly and no stumbling. Back it down to 35 and it ran perfect . Still getting a a little leak. I’ll clean up the needle again and try the light tap with the hammer trick to seat it.

Re: Stromberg LF
Lapped in the float needle with polishing compound today. Put everything back together. No leaks. I’m amazed how well it runs with the LF. With the OF being an upgrade over the LF no wonder they are so sought after. My T is not built for speed and I enjoy 30-35 mph. Next weekend I’ll check the new z head for clearance and get it installed. Lots of steep hill here in Western Massachusetts, hopefully the two will improve performance.

Re: Stromberg LF
Haven’t had a chance to install the Z head yet, but I am enjoying just getting out for rides. Cars starts as easily as with the the Holly G. Cruises right along at all speeds with no stumbling. One click ether way makes a big difference with the high speed needle. I think I have it dialed in. It’s been Definitely worth the time getting the LF installed.
