One thing I have noticed is that my carb throttle plate was not always closing fully at idle because of insufficient spring tension in the accelerator linkage spring. The spring attaching tang was adjusted towards the carb side, so I backed out the nut towards the firewall side to increase the spring tension. It is now only about 0.5" from the firewall end of the threaded rod. Spring tension is better, but still not very far extended. But now I notice that I have taken away travel in the accelerator floor treadle. It is half way to the floor at idle! Is my spring too long? It measures 1.5" of coils and 3.3" end to end.
Here is a picture of the spring and linkage attachment. You can see the spring is not very extended.
I just had a thought. Is there any reason that I couldn't move the linage attachment nut to the carb side of the rod and move the spring tang to the firewall side of the rod? This would improve the range of movement of the accelerator treadle while keeping good tension on the return spring....
Two things you can do. You have the civilian-model tab on the carb stud. You could bend the rod spring tab toward the firewall and/or secure the shorter military spring. I have a few in stock. I could just toss one in the kit.
binthere: Thanks for the coffee, +79 and had to add rum to the cup.

Scoutpilot: I'm having problems with my eMail accounts. A couple of marketing bots have found a weak spot and I'm being bombarded with spam and junk. Contact me here if you need anything.

oilleaker1: Scout had the same. Google the name of the Bot and you can go in and delete it from your programs with the instructions.

wkwillys: I doing a full military resto on a 50 Willys M38; re-manufacturing the engine now. I'd like to have the carb freshly rebuilt by you if you do these. Carter YS, tag 637S G6, side draft with vent. Do you also rebuild fuel/vacuum pumps? Thanks. John

oilleaker1: WK, I've rebuilt two M38's and a M38A1. Scout is your carb guy for sure. They are difficult. (not a side draft carb) If you have a question, try me, I'll be glad to help, Oilly

wkwillys: Good morning Rick. I'm ready to send my Carter YS and my fuel/vacuum pump, but I can't seem to get my computer to show the Service Form so I can fill it out. What might I be doing wrong?
