I've replaced head temp sender, Trigger point & Pvc valve. My cold start valve also is bad. Just unhooked it for now. My little leech ran great for about 10 days after I got it back from the shop. Now its back to doing the exact same thing. Running really rich & backfiring with a nice black cloud out the muffler. I don't want to switch to carbs but this is beyond me & no wrench around here seems capable of fixing it. Or at least fixing in a reasonable amount of time. What do I have left to replace to make this work right. Aux air cooler? All my injectors are new in Oct & hasn't seen much use since then. I would love to get it fixed but am sik of throwing the $ down the drain. Carbs may be my easiest option even though I hate to do it! Please help
