update my tractor

I picked up a TSC 241-like carb and used it as a refit on an old continental red-seal stationary engine as the mounting flange was correct .. It worked right out o fthe box with just minor mainjet tweaking..

EI? If you are having spark problems.. I suggest you check out the usual stuff first.. like ignition switch, wireing conenctions..etc, otherwise you may compound your problem.

I also suggest that if you go EI.. get the kit that eliminates the weak front mount coil, and instead lets you use a conventional round can coil. That takes all the 'resistor' questions out of the loop. Cost is more $$.. but as you said.. you just want it to be reliable.

There are ways to make your own round coil conversion.. but if you are going EI.. might as well not jurry-rig it..

Ya want affordability? Iff'n you can't do it, then have yer carb professionally rebuilt. DO NOT recarb with ZENITH. (my opinion only) The M/S is eminently rebuildable. $250 tops. Full kit is just $40 (cheap) Iff'n yer an electronically challenged shadetree mechanic, hire yer electronic conversions done. $250 tops. New points just $15 (cheap) Change yer weaksister ignition switch. $15 (cheap) will fixx yer weak sparkies.

The M/S is not hard to correctly adjust. Both Ford and M/S say to adjust both the side-pointing idlemix and down-pointing mainjet to 1-turn. That is just a starting point. Much to the dismay of gov't smog bureaucrats each and every carb must be individually adjusted to the its specific engine.

I set the down-pointing mainjet to 2-turns and LEAVITTT!!!! I then adjust the side-pointing idlemix for maximum idle rpms, NOT SMOOTHEST, max idle. I then adjust the behind the carb idle-speed to an incredibly SLOOOooow 400rpms. (ennythang under 500rpms is probably close) I do the idlemix and speed song'n'dance at least 3-times; always adjust for max idle speed, NOT smoothest. UNDERSTAND???

Remember the side-pointing idlemix is BASSACKWARDS; out for lean, IN for ENRICH. The last time I adjusted my eazy starting 6-volt 52-8N, my idlemix was 1/4-turn and idlespeed was 410rpms. Yours should be similar. Simple, eh?..... ..respectfully, Dell

I just can't IMAGINE what some of you guys do to your tractors to have so many problems!

(That being said, I have several other tractors that have EI, and even one that has EFI, however, that is because my son and I like to experiment with what CAN be done to old tractors, not necessarily what SHOULD be done to the poor old things!)

Almost certainly, there's nothing wrong with your carburetor that a kit and some detailed attention can't fix!
